PPC remarketing: What it is, how it works, and why you should use it

You’ve managed to create ads for your clients that are getting engagement from prospects, which is a huge win. But what happens when someone clicks the ad, browses your client’s website, and leaves without converting?

PPC remarketing keeps your client top of mind, reinforces their value proposition, and prompts them to take action. Done right, remarketing turns missed opportunities into measurable results, allowing your agency to maximize your client’s ad spend and deliver better ROI.

It’s also one of the most reliable places to put budget. You’re spending on people who have already engaged with your client’s brand, not on strangers, and agencies are constantly making high-stakes decisions where clients need to see a return on their investment. The real question isn’t why agencies should care about remarketing. It’s why they aren’t already using it.

In this guide, we’ll break down how PPC remarketing works and share best practices you can implement for your clients so every campaign gets results.

Key takeaways

• Remarketing targets people who already engaged with your client’s brand, and 26% of users return to a website because of it.

• Segmentation decides the outcome: page-level behavior, time on site, cart abandoners, and repeat visitors each need different messaging.

• The tracking window should match the buying cycle, from around 30 days for quick purchases to 60–90 days for considered ones.

• Display, search, email, social, and video formats suit different clients, so match the format to how the audience actually buys.

• Frequency caps, converter exclusions, and accurate conversion tracking keep budget on people who can still convert.

What is PPC remarketing?

Pay-per-click (PPC) advertising refers to paid marketing campaigns across platforms like Google, LinkedIn, and Instagram–anywhere you pay to put a brand in front of the right audience.

Remarketing is a strategy designed to re-engage people who’ve already interacted with your client’s business. These potential customers might have:

• Searched for your client’s brand on Google

• Clicked on a paid ad

• Browsed a product page

• Abandoned their shopping cart

• Completed a previous purchase

By staying visible to these warm leads, remarketing keeps your client’s brand top of mind and nudges them closer to conversion.

But for ads to be effective, you need the right strategy.

Think of it this way: a potential client is looking for an auto repair shop they can trust. They land on your client’s website through a Google search and spend time browsing, especially on the brake repair and preventative maintenance pages. They like what they see, but they’re not quite ready to schedule a service. The idea lingers–a seed is planted.

The next day, they see your client’s shop pop up in a LinkedIn ad. That’s no accident–it’s remarketing in action. Because they’ve already engaged with your client’s brand, the ad doesn’t feel random or intrusive. It reinforces a connection, and your client is top of mind again. A well-placed remarketing ad is the nudge that turns initial interest into action.

Why remarketing works

The numbers tell the story. 26% of users return to a website thanks to remarketing. That’s over a quarter of potential customers coming back for another look.

Remarketing helps businesses reconnect because these aren’t hesitant buyers. They already trust your client and know the brand delivers. Without remarketing campaigns, many of those leads could slip into the bounce-rate abyss, potentially lost forever.

A happy customer will sometimes come back on their own, but why leave it to chance? People are busy. Between juggling work, family, and endless to-do lists, even the most satisfied customer might forget to return. A well-placed remarketing ad is often the only nudge they need.

Remarketing matters even more for clients with a wide range of products or services. Their customers might love what they’ve purchased, but they may not know about other offerings. Targeted campaigns introduce those additional products and keep the relationship going.

Relevance is what makes it land. 79% of consumers only engage with offers that reflect their previous interactions. Generic ads are disruptive and, frankly, annoying when someone is trying to enjoy their downtime. Remarketing ads are tailored to a person’s needs, so they’re much more likely to earn engagement.

What's the difference between PPC remarketing vs. PPC retargeting?

Both remarketing and retargeting involve re-engaging potential customers. While the terms are often used interchangeably, they do have different meanings, and they serve different parts of the sales funnel.

When we say retargeting, we’re talking about serving ads to people who have visited specific pages of your client’s website. Think of someone who checked out your client’s shop window, loved what they saw, and walked away without buying.

This requires setting up tracking tags on your client’s website that track website visitors along with specific rules for each type of visitor. For example, you might use LinkedIn to target everyone who lands on a certain landing page but doesn’t fill it in. The next time they’re on LinkedIn, they’ll see your client’s ad, reminding them of the benefits of their offer with a link back to the landing page. Google Ads, Facebook, and LinkedIn all have their own ways of tracking repeat visitors, whether that’s tags, pixels, or scripts.

Retargeting is a great way to get more people to become contacts, progressing these leads through the buyers journey and bridging gaps in your client’s marketing funnel.

Remarketing refers more broadly to a multichannel approach, in which prospects are nurtured through a combination of ads and other efforts like follow-up emails. Email nurturing sequences target a client’s potential leads or existing customers to build trust, drive engagement, and encourage repeat business. Say a lead downloads an offer from your client’s website. You use those details to follow up, keeping them updated on similar products or services and special offers.

The practical difference: retargeting works on custom audiences that are close to purchasing, while remarketing acts as a softer touchpoint across the whole relationship and builds long-term loyalty.

How PPC remarketing works

When someone visits your client’s website, it’s a sign they might be in the market for what they offer. The visit is a first step, but the context (traffic source, engagement, behavior) matters more.

Site visitors might not be ready to buy just yet, but they’ve entered your client’s orbit. Remarketing is how you keep them there, reminding them of the brand through tailored ads, email follow-ups, or a perfectly timed LinkedIn placement.

The ability to identify your ideal customer and remarket to that specific segment is extremely lucrative to high-volume agencies within a specialized industry.

By tapping into remarketing campaigns and smart audience targeting, your agency will boost conversion rates, stretch your client’s ad budget further, and keep them top of mind when it matters. Close the loop with PPC report automation so results are summarized for clients automatically. Pair that with marketing attribution models to better understand which touchpoints are driving conversions and how to allocate your client’s budget more effectively.

Here’s a closer look at how PPC remarketing works:

1. Audience tracking

A remarketing tag (or pixel) is installed from platforms like Google Ads, Facebook Ads, or LinkedIn Ads on your client’s website or app. This pixel tracks visitors and adds them to custom audiences based on behavior cues like:

• Pages visited

• Time spent on site

• Actions taken (or not taken)

• Previous purchases

2. Audience segmentation

Next, the audience is broken into specific groups so your agency can tailor the messaging they’ll receive. Segmentation is where remarketing is won or lost. How much time someone spends on your client’s site, how many pages they view, and which specific pages they visit all influence whether you take a nurturing approach or go in with a more direct message.

Start with the behavioral segments almost every account needs:

• Cart abandoners: They were this close to making a purchase. Messaging may include ads reminding them of their product, a discount code, or a nudge built on urgency.

• Past purchasers: Upsell or cross-sell messaging works well here.

• Page-level behavior: Create different lists for visitors who browsed your client’s pricing page, blog, or service pages. Each has a different intent and requires a different follow-up.

• Time on site: Someone who spent 5+ minutes on your client’s site is warmer than someone who bounced after 10 seconds.

• Repeat visitors: These users are showing deeper interest. Serve them content that builds trust and moves them closer to becoming paying customers.

We use broad targeting with automated campaign optimisation over time, which hones in the targeting and bidding to reach the right users at the right time. With eCommerce activity, usually catalog ads work best, both from an Acquisition and Remarketing standpoint. Promo offers are essential for capturing user attention and driving demand for products.

Take a client in the fitness industry selling gym equipment, supplements, and fitness gear. Their audience splits into several segments, and each one needs a different ad.

• First-time buyers: These customers made a recent purchase, like a set of weights or a yoga mat. They’re still getting to know the brand, so remarketing ads here should focus on reinforcing trust, perhaps promoting blogs on how to use the product they just bought or introducing complementary items to encourage a second purchase.

• Frequent buyers: Loyal customers who regularly buy from the brand, think monthly orders of protein powder or new workout gear every season. For them, remarketing tactics should lean into exclusivity. Ads might highlight loyalty rewards, early access to new products, or special offers that make them feel valued.

• ‘Lost’ customers: People who haven’t bought anything in a while. Maybe they used to be frequent buyers but drifted away. For them, you need a more enticing approach: time-sensitive offers or incentives like “We miss you! Here’s 20% off your next order” could rekindle their interest.

The more precise your segments, the more relevant and effective your client’s ads become. Precision is what makes ads speak to people as individuals, and that leads to more conversions and better customer relationships.

3. Targeting and creative

Using this information, messaging is highly personalized based on past behavior. These customers may be served paid ads, or receive a specific email nurturing sequence to encourage specific conversion behavior.

• Dynamic remarketing ads show the exact product the person viewed.

• Seasonal offers are sent to past customers.

• Urgency-driven messages (“Only 2 left in stock!”) are effective levers.

4. Ad placement

From here, ads follow users across:

• Search networks: Google Search ads are triggered when they search related terms again.

• Display networks: Banner ads are displayed on other websites.

• Social platforms: Ads may appear on Facebook, Instagram, LinkedIn, or TikTok.

Facebook advertising is important for businesses as the Meta company (and thus Facebook or Meta Ads) enables business owners to advertise across all Meta platforms. Additionally, it's a great way to remarket to your audiences in a place that feels natural to them.

5. Conversion tracking and optimization

As the remarketing campaign rolls out, your agency measures performance by tracking clicks, conversions, and ROI for each audience segment. Importing offline conversions from the client’s CRM into Google and Facebook will improve remarketing targeting quality by focusing on high-quality leads.

Some common optimizations include:

• Frequency capping to avoid ad fatigue.

• Adjusting bids for high-intent audiences.

• Testing ad creatives for better CTR and conversion rates.

Advanced measurement tactics like incrementality tests, holdout groups, and geo-split testing will also help agencies to prove that remarketing is actually driving net-new conversions.

Remarketing ad formats

Different formats do different jobs. Here’s a closer look at the main remarketing ad formats, and why an agency might choose each one.

Display remarketing

Display ad remarketing is one of the most popular forms, and it involves using Google Ads to target users who have already visited your client’s site.

Standard display shows generic remarketing ads to users as they browse other sites in an ad network (like the Google Display Network). These ads are great for maintaining brand awareness and fostering a renewed interest. The goal is simple: remind users of your client’s business without being too specific.

Dynamic remarketing personalizes your Google Ads by showing site visitors the exact products they viewed previously. So if someone was eyeing a pair of shoes, a dynamic remarketing ad campaign will remind them of those shoes, making it far more likely to convert them into buyers. Dynamic remarketing is costly but highly effective for ecommerce businesses, as it delivers a tailored experience​.

Search remarketing

Search remarketing campaigns target past customers, such as those who’ve previously visited your client’s site or made purchases, by showing them ads when they search for related keywords on Google.

These Google Ads appear at the top of search engine results pages (SERPs), which makes them highly visible and effective for capturing attention, provided you have the right target audience size and an ample ad spend budget.

For example, a client with 35,000 active site visitors each month sees great success with search ads because their traffic volume is large enough to support it. When you’re dealing with big numbers, even small conversion rate improvements add up to significant gains.

Search remarketing isn’t for everyone, though. If users are already searching for your client’s product or service, they likely have intent to buy and may not need much extra persuasion, so the spend can feel redundant.

Email remarketing

Email remarketing involves sending tailored messages to users who’ve engaged with your client’s business before, whether they’ve left items in their cart, made a purchase, or signed up for a newsletter. The real power here is personalization: address customers directly, send product recommendations based on their behavior, or reward loyalty. It’s perfect for boosting repeat purchases and nurturing long-term customer relationships (provided you have an effective EDM strategy!)

If there’s one email remarketing tactic that consistently delivers, it’s shopping cart abandonment reminders, and they’re worth including for every ecommerce client. When someone adds an item to their cart, they’re already so close to buying. They’ve scrolled, compared, and clicked “add to cart.” They just haven’t hit “buy” yet.

One mid-sized online retailer was skeptical about cart abandonment emails, assuming their customers would come back on their own. As soon as automated reminders started going out, their sales began rising. A well-timed message like, "Looks like you left something behind," was enough to bring customers back to complete their purchase. Add a small incentive, like 10% off or free shipping, and those potential customers soon became buyers.

Don’t stop at the one-off conversion. Post-purchase emails offering a discount on the next order build customer lifetime value and loyalty. A “Thanks for your order—here’s 10% off your next one!” goes a long way in getting customers to return, whether they come back for new products or use the discount on something they were already eyeing.

Social media remarketing

Social media platforms like Facebook, Instagram, and LinkedIn offer wide flexibility for remarketing campaigns. They enable you to serve ads to users who’ve visited your client’s site, interacted with their social media content, or even engaged with specific posts.

The best part is the diversity of formats: videos, carousel ads, stories, or simple posts, all available to capture attention.

Social media remarketing ads are ideal for brands with strong visual elements or businesses that thrive on direct customer engagement. You’ll create ads that stay visible in a space where your client’s audience spends a lot of time, making it easier to re-engage them with new products, promotions, or content​.

Video remarketing

A video remarketing campaign involves showing video ads to users who’ve previously interacted with your client’s brand. Video ads are ideal for platforms like YouTube or when integrated within social media feeds. Video remarketing is highly engaging when done well, because it’s hard to ignore a compelling story or product demo.

This type of remarketing works best for businesses that showcase their products or services visually. It’s great for building brand awareness or delivering a strong message to bring users back to your client’s site​.

Google Ads remarketing features

Google Ads offers a powerful suite of remarketing tools that help you stay connected with your client’s potential customers long after they’ve left their site. With Google Ads' flexible remarketing options, you can build campaigns that feel timely, relevant, and personalized without coming across as pushy.

At the heart of it all is the Google Ads remarketing tag–a simple snippet of code that tracks user behavior on your client’s site and helps you build targeted remarketing audiences.

Here’s what you can do with it:

• Standard remarketing: Show ads to past visitors as they browse websites and apps on the Google Display Network. Great for keeping your client’s brand visible while they surf the web.

• Dynamic remarketing: Take it a step further and create personalized ads featuring products or services they viewed on your client’s site.

• Remarketing Lists for Search Ads (RLSA): Customize your client’s search ads and bids for users who’ve already visited your client’s site. This way, you’re prioritizing people who are already familiar with their brand when they’re actively searching on Google.

• Video remarketing: Re-engage users who interacted with your client’s YouTube videos or channel. Whether they watched a product demo or skipped halfway through, serve up relevant video ads as they continue exploring YouTube or the Display Network.

• Customer match: Upload your client’s customer email list and reach those users across Search, Shopping, Gmail, YouTube, and Display. It's a smart way to re-engage existing leads or upsell current customers.

• App remarketing: Target people who have used your client’s mobile app but haven’t taken a specific action yet, like completing a purchase or signing up for a service.

Best practices for effective PPC remarketing

PPC remarketing gives your client a second chance at customer acquisition. It’s a key part of smart PPC management and should be baked into your clients’ broader strategy, not just tacked on as an afterthought.

Here’s how to make it count.

Match the remarketing window to the buying cycle

The length of time your client’s tags and pixels track site visitors is crucial, and it isn’t a one-size-fits-all setting. Different industries mean different buying cycles, so the time window you set should reflect how long your client’s potential customers take to make a decision.

Consider technology-based products. High-ticket items like sound systems or gaming PCs require careful research and comparison shopping, which is why a 60-90-day remarketing window is ideal. It gives buyers time to consider their options without forgetting about your client.

A homeware brand operates on a shorter timeline. Buying a new set of plates or a throw pillow is often a quick decision, made in days or weeks. A 30-day window makes more sense there, keeping your client top-of-mind just long enough to prompt a purchase before the ads lose relevance.

These differences show up in the results. One rural equipment retailer originally had their window set to 30 days. But for a farmer investing thousands in a baler, the decision takes time, and they were losing leads right when buyers were ready to convert. After extending the window to 90 days, they saw a significant boost in conversions.

Write ad creative that earns a second look

When it comes to ad creative, don’t be afraid to take risks. Not everyone fits the profile of the audience you’re targeting, and that’s okay. The worst thing you can do is play it safe and try to appeal to everyone, as you’ll almost certainly end up just blending into the background.

Here are some tips to help create targeted ads that help your client stand out and make an impression:

• Match the message to the moment: Reflect what the user last saw, whether it was a product, a service, or a blog post. Continuity builds trust.

• Add urgency: Limited-time offers or low-stock notices can tip someone from “maybe” to “yes.”

• Use dynamic ads: Dynamic remarketing delivers customized ads that showcase the exact products or services users previously viewed, making your client’s ads feel relevant and timely.

• Keep visuals fresh: Avoid ad fatigue by rotating visuals and copy regularly.

• Test, test, test: A/B test different headlines, images, CTAs, and ad formats to see what clicks with target users.

Don’t be stingy with free value

It might sound controversial to invest in remarketing ads that lead to blogs, eBooks, or other "free" resources when your client’s primary goal is conversions. But your remarketing campaign shouldn't only be about getting an immediate sale. Customers appreciate a brand that offers genuine value beyond a sales pitch, and those interactions have a lasting impact. If a customer engages with a helpful or entertaining piece of content using TikTok ads for example, they’re far more likely to remember your client’s brand down the line, even if they don’t convert right away.

Content engagement also tells you who is worth pursuing. If website visitors take the time to read a 1,000-word blog post on "Guitar Tips for Beginners" from start to finish, it’s a solid sign that they’re highly engaged and genuinely interested in buying an instrument. That lead is far more valuable than someone who briefly browsed the site.

Many consumers experience ad fatigue, so offering something for free is a subtle reminder that your client’s brand values engagement and education. Over time, this approach builds trust, authority, and brand loyalty. It might not feel as immediate as a discount or free shipping, but it pays off in the long run.

Enhance the initial purchase

For stores that sell a variety of items, enhancing the initial purchase through targeted upselling and cross-selling is a remarkably effective strategy.

A customer just bought a shiny new smartphone. That’s not the end of their buying journey. It’s an opportunity to offer complementary products, like a phone case or screen protector. These add-ons are cheaper than the main item but highly relevant, providing value to the customer and a way to increase sales.

The strategy taps into the sunk cost fallacy. Once someone has made a significant investment, whether it's in a phone, a laptop, or high-end kitchen appliances, they’re more likely to justify spending a bit more. If they’ve already spent $1,000 on a new phone, what’s an extra $20 or $30 for a case to protect it? That mindset is the perfect opening to introduce related products that complete the purchase experience.

Bid according to segment value

Your bidding approach should reflect how valuable each audience segment is. Here’s how to make the most of your ad spend:

• Use target CPA for conversion-ready segments: For high-intent audiences (like cart abandoners), targeting Cost Per Action ensures you're not overspending on conversions.

• Maximize clicks for cold-to-warm audiences: If you’re just starting to warm up your client’s site visitors, a Maximize Clicks strategy can drive traffic efficiently. That said, for warm remarketing audiences, Maximize Conversions (with a CPA cap) is usually more efficient once there’s enough conversion volume. Maximize Clicks will sometimes bring irrelevant traffic if left running for too long,

• RLSA for strategic search re-entry: Remarketing Lists for Search Ads let you adjust bids when previous visitors search again, giving you a second chance to close the deal. It’s also worth noting that Google Search remarketing lists require a minimum of 1000 active users before ads can be served, which is important for smaller audiences.

• Adjust bids by segment: Someone who visited a high-value page deserves a higher bid than someone who bounced in 3 seconds. Prioritize accordingly. A dedicated PPC dashboard helps you monitor these audience segments and adjust your strategy in real time.

Common PPC remarketing mistakes to avoid

Remarketing is a wildly effective tactic–but only if done right. Without a thoughtful strategy, you risk annoying your client’s audience or wasting ad spend.

Take one client as an example: a big spender with a great service, a stack of leads, and an ample ad budget. They had it all except for one massive oversight. They were running the same ads for everyone, first-time visitors and existing customers alike. Giving a loyal customer the exact same pitch as a stranger is awkward, and it’s a money drain. Previous customers are hotter leads, and when ads aren’t tailored to them, budget goes on messaging that doesn’t hit the mark. They already know the brand. They want to know why they should buy again.

That scenario plays out time and time again. Here are the pitfalls to steer clear of:

• Going too broad: Targeting everyone who lands on your client’s site with the same ad is a fast track to irrelevance. Segment your client’s audiences based on behavior–like pages viewed or time on site–for more personalized, effective follow-ups.

• Ignoring frequency caps: Just because someone clicked once doesn’t mean they want to see your client’s ad 47 times a day. Set frequency caps to avoid ad fatigue and putting people off by being overly persistent.

• Forgetting to exclude converters: Nothing’s more awkward than continuing to advertise to someone who already bought from your client. Exclude converted users from your remarketing lists to save budget and avoid confusion.

• Using generic creative: If a client’s ad copy or creative doesn’t reflect what their visitor actually looked at, it won’t resonate. Use dynamic remarketing when possible, or tailor ad content to align with their past activity.

• Not tracking conversions properly: Without accurate conversion tracking, you’re flying blind. Make sure your client’s tags and goals are set up correctly so you can measure what’s working, and what’s not. Using a well-designed PPC report template will help you visualize this data clearly and spot trends.

• Running the same stale ads: If your client’s remarketing ads feel outdated, they’ll get ignored. Refresh creatives regularly to keep things fresh and avoid banner blindness.

Maximize your marketing strategy with smarter remarketing

Remarketing isn’t only about giving customers a second chance. It’s about making every interaction count, from bringing back cart abandoners to keeping loyal customers engaged. A simple, well-timed nudge brings people back ready to convert.
