The Benefits of SEO: What To Tell Clients About Their ROI and Beyond

ROI Benefits of SEO

There is little doubt in a digital marketing professional’s mind that SEO is one of the most important aspects of any inbound marketing strategy. But every now and then, there’s a client that is just looking for quick results and is hesitant about investing in SEO. How can you outline the benefits of SEO? What impact can SEO have on your client's ROI beyond the organic metrics? 

This article will outline the direct benefits of SEO to convince your clients, and discuss how your agency should include the complete picture of SEO ROI in your next SEO proposal. We'll also talk about some tangential benefits that many business owners don't think about but should consider!

In this post, we’ll cover: 

Search engine optimization is essential for a variety of reasons. First and foremost, it can tremendously impact your client's website traffic. By optimizing their website for search engines, your agency ensures that they appear as high up in the search results as possible. This, in turn, leads to more website visitors, leading to more sales and conversions.

But measuring SEO ROI isn't just about more traffic–it's also about better quality traffic. By appearing in the top search results for targeted keywords, you're not just attracting any old visitors–you're attracting visitors who are specifically interested in what your client has to offer.

What to tell your clients: These people are far more likely to convert into paying customers because they are actively searching for a solution to a current problem they are having. This is why SEO will positively impact your bottom line in the long run. And it will keep doing so without necessarily putting in any ad dollars!

Beyond that, SEO can also have many other benefits for your client's business. For example, SEO builds brand awareness and credibility. When potential customers see your client's website appearing in the top search results, they'll start to associate your client with being a leader in their industry, which is essential for any business that wants to succeed online. And as we all know, trust is one of the most important factors when making a sale.

We’ll get into those additional benefits, but first– let’s help you explain the basics to your clients. This will help them understand their client SEO reports down the line, so they understand the total SEO ROI impact your agency is making.

Core Benefits of SEO

The baseline for any SEO program starts with organic search metrics.

  • Traffic: The first and most obvious metric is traffic.

  • Rankings: Of course, traffic means nothing if those visitors aren’t coming from searches that match what your client has to offer.

  • Backlinks: Quality backlinks continue to be one of the most vital ranking factors, but quality backlinks can also drive referral traffic from relevant websites.

  • Conversions: Once you have increased your traffic AND the quality of that traffic, you should see an uptick in conversions (leads, sales, etc.).

  • Revenue: Finally, the ultimate goal of any business is to make money and generate a positive return on investment.

To successfully execute an SEO program for any client, it's essential to regularly track and measure these data points. That should be a given.

But it's important to remember–especially when trying to sell SEO services to someone who isn't already on board the SEO train–that SEO ROI goes well beyond the core metrics, and there are several reasons why.

What to tell your clients: Tracking core SEO metrics is important for measuring the direct impact of SEO on ROI, but it’s only a piece of the puzzle. It’s important to keep a view of the other benefits that SEO provides to a business. 

Why Clients Should Embark on an SEO Journey

In today's fast-paced digital world, everyone–including your client–wants everything yesterday. But some clients fail to realize that while it takes time to see ROI results from an SEO program, the benefits of those hard-earned rankings last much longer than any other marketing initiative.

What your clients should know: 

1. Good SEO Takes Time, but the ROI Benefits Are Long-Term

One of the most common misconceptions about SEO is that it's a quick fix. Many business owners think they can just throw a few hundred dollars at an agency and see results overnight. Unfortunately, that's just not how it works.

Although fixing your clients' load time, or fixing technical SEO issues can be quick, and can make an impact on the overall user experience and rankings.

Good SEO takes time–usually several months, sometimes even longer. And not every client has the patience to wait for it to kick in. But once your client ranks higher in the search results, they'll begin to see a steady stream of organic traffic coming to their website day after day, month after month, year after year. And as we mentioned before, that traffic is typically higher quality (as long as you have your keyword targeting done right) which means it has a good chance of converting into sales, revenue, and positive ROI for your client.

Agency Tip: To overcome this objection, include some examples from past clients and show the growth of their organic results over time. That way, they can see for themselves the slow climb up the mountain–but be able to picture the view from the top. 

2. SEO is an Investment, Not a Cost

Another common misconception about SEO is that it's a cost that takes money out of your client's pocket with no guarantee of any return on investment. But if you look at SEO from a long-term perspective, it's easy to see that it's actually a strategic investment in the future of the business.

Yes, there are upfront costs associated with hiring your agency. But those costs will be more than offset by the increased organic traffic, revenue, and ROI your client will see down the road.

And although they are right that there is no “guarantee” of success in the SEO world, a properly executed SEO strategy will drive results more often than not. 

Think about it this way–if your client spends $5000 on a PPC ad campaign, they might see a bump in sales for the month the ads run. But once that ad campaign is over, so are the benefits.

On the other hand, if they invest $5000 in an SEO program that delivers results over 12 months, they'll continue to see benefits–and traffic and sales–for months or even years down the road.

Agency Tip: Including a Cost/Benefit analysis comparing the ROI of paid demand generation vs. SEO campaigns can help put this investment into perspective. 

3. Search Engine Optimization Is Never One and Done

SEO is an ongoing process, not a one-time fix. To maintain and improve your client's rankings, you'll need to continue to work on their SEO. This includes regularly publishing new content, adding new backlinks, and ensuring their website is always up-to-date and provide the best user experience for their potential clients..

But the good news is that once you've established a solid foundation for your client's SEO program, the ongoing work will be much easier–and less time-consuming–than it was initially.

Agency Tip: Show quick wins early–such as obtaining a #1 ranking for a targeted keyword–and connect the dots between the increased organic presence, leads, and revenue. This will highlight the power of SEO to drive ROI long-term.   

4. Google Keeps Changing, but SEO Keeps Getting Stronger

Finally, it's important to remember that search engines like Google constantly changes its algorithm. And with each new update, there's always the risk that your client's rankings could take a hit.

But, despite all of Google's changes, search engine optimization has only gotten stronger over the years. And as long as you stay up-to-date on the latest SEO trends and best practices, you'll be able to adapt your client's SEO program to whatever changes come down the line.

Agency Tip: An SEO audit is an excellent way to show how well (or poorly) the potential client’s current website is perceived by search engines. They may not even realize their SEO shortcomings.

SEO Is More Than Just Rankings and Traffic: It's Also About Branding, Trust, and More

One of the less tangible benefits of SEO that many clients don't think about is branding.

Top rankings in organic search results give your client credibility. 

Studies have shown that, on average, 70 to 80% of people research a company or product online before making a purchase–so your clients must have a strong SEO program in place if they want to stay ahead of the competition and drive sales.

Percent of Customers Who Research Online Before Buying

Here are some more points in favor of SEO when setting long-term goals with your clients: 

1. Increased Remarketing Pool

Remarketing is typically one of the most cost-effective advertising methods within the digital marketer's toolbox. That's simply because the user already has expressed an interest in the content, products, or services provided.

SEO is a cost-effective way to increase the size of your client's remarketing pool. If you can solve a customer's fundamental problems using content or tools, they are more likely to turn to your client when looking for solutions to their more complex problems. Even if you give the target customer a fun way to interact with your client, once they've visited your client's site-they are ripe for remarketing.

Of course, the remarketing approach must align with the original content the audience consumes. Just because someone read a blog post your team created to support the client's SEO strategy doesn't mean that the visitor is ready to buy. Use remarketing to take the user through each step in the typical buyer's journey.

2. Improved PPC Click-through Rates

It's been over a decade since Google first announced that when a site has high organic search results, they are likely to see an increased click-through rate for paid ads on the same search engine results page (SERP). That still holds true today. 

Having both an organic and a paid result on the first page of Google increases the amount of virtual real estate your client owns on that page, and they help support each other by giving a sense of authority to the brand.

After all, if Google thinks your client's website is authoritative enough to rank in the top 10, why would the consumer disagree?

3. SEO Drives Local Foot Traffic (and Phone Calls)

This is one of the biggest benefits of SEO for a local small business. You may never see the clicks involved, but search engine optimization is well-known for driving traffic into a local office or retail storefront and phone calls for local service providers.

People searching for “dentist near me,” “buy building supplies,” or “best real estate agent” are close to the point of purchase. Your client's business should come up in the results list with the right local SEO strategy, including their location, hours of operation, and phone number.

These users might not even click on the link to visit your client's website, but they may pick up the phone or hop into the car. With the right SEO strategy and proper local schema markups, your client's website appears in these searches–and gets the foot traffic they need to drive sales and increase ROI.

4. Reduced Marketing Spend

The average cost per click on Google ads is between $1.00 and $2.00. And that's typical for low-competition keywords. Some of the highest CPCs can cost your client somewhere in the $40 to $50 range. For example, here are the five most expensive CPCs:


Average Cost Per Click (CPC)

All else being equal, every click your team can generate via search engine optimization (SEO) versus search engine marketing (SEM) is one less click your client needs to pay for if they want to maintain consistent traffic levels.

Although using paid ads to fill the traffic gap is common, your agency (and your client) can decrease its reliance on paid traffic sources as the organic strategy delivers.

5. Building Authority

A well-executed content marketing plan is a great way to build organic strength and an excellent way to show that your clients are experts in their field.

Think about it. If a user reads a well-written, informative piece about digital media analytics, they are likely to connect that source as an expert on that topic. This is especially helpful in some instances, such as law firm marketing, where restrictions prevent clients from claiming that they are experts. SEO content lets them prove it without ever having to say the words. 

This can help boost the client's authority among a variety of different types of readers, including (but not limited to):

  • Potential customers

  • Industry experts

  • Potential employees

  • Other publications (web and print) that source the material in their posts

What to tell your clients: If you are not paying attention to how SEO impacts the rest of your business, you might miss out on some growth and ROI opportunities. 

SEO Is an Investment That Keeps on Giving

Countless benefits of SEO–both tangible and intangible–make it well worth the investment for any business, big or small.

SEO is essential to any successful online marketing strategy, from increased traffic and sales to improved branding and trust.

If you're not already incorporating SEO into your client's marketing mix, now is the time to start.

Your clients–and their bottom line–will thank you for it.

What to tell your clients: Although SEO takes more time to get the ball rolling than traditional paid ads, once that momentum has been built, it becomes a snowball of ongoing ROI. Avoid any unrealistic expectations with your SEO clients.

The Many Benefits of Hiring an SEO Company

There are countless reasons to hire an SEO agency like yours to help improve a website's search engine rankings. Here are some benefits you should be highlighting within your proposal.

  1. Expertise and Experience

  2. Focus on the Right Things

  3. High-quality Content

  4. Enough Time To Do It Well

First, your agency has the expertise and experience to help the client's business achieve higher rankings on search engine results pages (SERPs). You keep your fingers on the pulse of the latest trends and changes in the SEO landscape and have the tools and resources to stay ahead of the curve.

Second, as an SEO agency, you know how to focus your efforts on the areas that will generate more leads and traffic from organic search. With an eye on SEO ROI, you know how to create a comprehensive strategy that targets the right keywords and reaches the right audience. And you track the progress of your SEO programs and measure your results to show exactly how much ROI your client's investment generates.

Third, you have the skills and experience to build a more substantial online presence for your client's business. Your agency understands how to create high-quality content that engages readers and helps clients stand out from the competition. And you know how to maximize the impact of that content by developing effective social media marketing campaigns that amplify that content to help clients connect with new customers. Your clients may be excellent plumbers, but that doesn’t make them good writers. 

Fourth, an SEO agency can invest the time and energy required to do things the right way the first time. Most clients simply don't have the time to do this for themselves, which can often lead to cut corners and less-than-ideal SEO practices that will not provide the same long-term ROI benefits.

Five Really Good Reasons Why Clients Should Never Stop Doing SEO

1. The Algorithms Are Constantly Changing - In a single year, Google typically runs over 600,000 experiments and makes around 4,500 improvements to how it displays search results. That’s just a little over 12 changes per day, every day (even on Christmas).

2. If They Don’t Do It, Their Competitors Will - If you want to help illustrate that fact, tell your clients to search for practically anything on Google. Pick a term. Any term. For example, a search for “Marketing Agency” brings up 1.7 billion results.

3. How People Use Search Engines Is Also Changing - Between predictive search, personalized results, image search, and voice search, how people use search engines is very different today than it was just a few years ago. And it’s not going to stop changing.

4. Things Break When You’re Not Looking - There’s an old saying that a watched pot never boils. But an unwatched website will break, even if it’s in small ways. From links, images, server problems, mobile-friendliness, and site speed problems, you’ve got to keep a watchful eye on the technical aspects of SEO or things will slowly but surely deteriorate. 

5. Position Still Matters - Out of the millions, or even billions, of results that show up for each and every search that is performed on Google, only a handful of them will ever get clicked. Every day that you're not focusing on your client’s SEO is another opportunity for their competitors to push them down in the results (and one less opportunity for you to move them up).

How to Measure the Impact of SEO, Beyond Organic Traffic

While SEO has a lot of benefits, it can be hard to measure the impact if you're only looking at SEO KPIs. Here are a few other ways to use various metrics and KPIs to measure the success of your SEO efforts:

  • Overall Website Visitor Growth: Look at the total number of website visitors each month to see if there is an increase since starting your SEO efforts.

  • Leads and Sales: One of the ultimate goals of SEO is to generate leads and sales for your client. Track this by setting up conversion tracking in Google Analytics or another analytics tool. This will help you see the total sales generated and how the trend aligns with the SEO growth, even if they are not directly attributed to keywords or organic traffic sources.

  • Increase Brand Awareness: Another benefit of SEO is improved branding. This can be harder to quantify but look at measures like brand searches as a proxy for improved branding.

  • Trust and Authority: As your client's website grows in authority, they will see improvements in how users and Google perceive their website. This can improve brand awareness and trust, eventually increasing sales and conversions.

  • User Engagement: Finally, SEO can improve user engagement on your client's website. This can be measured by looking at the time on site, pages per session, and bounce rate.

All of these metrics are available in the Web Analytics Dashboard from AgencyAnalytics.

By looking at all these factors, get a well-rounded picture of SEO's impact on your client's business, not just their organic traffic numbers.

Adding These Benefits To Your Next SEO Proposal

When trying to sell a potential client on the benefits and ROI of search engine optimization, it's essential to focus on more than just the numbers. While improved traffic and sales are undoubtedly major benefits of SEO, they're not the only growth areas clients will experience from investing in an effective organic search strategy.

Be sure to highlight the other SEO benefits your client may not be aware of, including those discussed above. By doing so, you'll not only differentiate yourself from other agencies pitching similar services but also build trust and credibility with your potential clients by showing them that you understand their business and what they need to improve their bottom line.

Remind your potential client that SEO is an investment that keeps on giving, with benefits that extend far beyond the shortened timetables of most digital marketing campaigns. Focus on the total impact an effective organic search strategy can have on their business–from increased brand awareness and trust to improved hiring prospects and industry credibility.
