15 Best Link Building Tools for SEO in 2026

Let’s look at an all-too-common scenario. It’s 1 PM at the agency, and you’ve just finished your second (or maybe third?) cup of coffee. 

You hear that familiar ‘ping’ sound and glimpse an email notification pop up on your screen. Immediately, you sense your client’s anxiety from the heading— “URGENT: Higher Search Visibility Needed!!!” Before even opening the email, one of the first things that come to mind is sending an updated SEO proposal emphasizing the importance of link building. That's one of the reasons that a backlink overview is pre-built into our professional SEO proposal template.

For your clients to succeed in the digital realm, a solid link-building strategy must be part of an overall marketing strategy. But what are the best ways to find link building prospects and acquire these links? After all, there are active and passive link-building strategies, both of which have advantages and drawbacks.

A passive link-building strategy is a process of acquiring links without actively pursuing them. This can be done by publishing high-quality content that other websites will naturally want to link to. 

You can also promote your client’s content on social media and through email marketing to increase the chances that it will get links from other websites. Using a passive link-building strategy, you improve your client’s SEO and visibility without investing additional time or resources going after backlinks. After all, even with the very best link building tool, link outreach takes a significant amount of time and effort.

However, sometimes, a passive link-building strategy isn’t enough, and you must go on the offensive. For example, if the website is relatively new or the content isn’t generating enough links on its own merits. 

After all, if people can’t find your client’s content, they won’t be able to link to it. Your agency might need to do something to get that link ball rolling. This is where a more active backlink strategy–pursuing links from other websites–comes into play. And to do this efficiently, your agency needs the right link-building tool. 

There are many link-building tools out there, and it may seem like a daunting task to pick one. Perhaps you’re looking to serve enterprise clients with many links needed to move the needle, or you’re controlling expenses for a smaller business and prefer a budget-friendly (or even free) backlink finder.

Regardless of your preference, we’re sure there’s an option for you!

In this article, we’ll give an overview of:

• What is Link Building?

• Why Link Building Is Worth It

• When and Why Your Agency Should Start Link Building Campaigns

• Quality Vs. Quantity: The Great Link Building Debate

• What Happens If You Do It Wrong

• What Are Link Building Tools?

• The Best Link Building Tools for Your Agency
  

As we head into 2026, link building looks different than it did just a couple of years ago.

Machine learning, AI-powered search results, and new ownership/feature changes at major vendors mean agencies must focus on quality, relevance, and measurement.

Link building is still one of the most reliable ways to build search authority — but the way we find, pitch, and measure links has evolved. Today’s best link building tools combine a large backlink index, smart prospecting, outreach sequencing, and easy reporting so teams can scale outreach without losing quality. This guide shows which tools agencies rely on, what to expect from each platform, and how to stitch tools together into a repeatable link-building workflow.

Read this if you want a practical shortlist and a battle-tested workflow for building editorial, high-quality backlinks that move the needle.

What is Link Building?

Link building is a commonly used SEO strategy that helps bolster your client’s web visibility by acquiring links on other websites. Not only does it establish brand authority for that brand, but it also ticks a checkmark for Google when they’re rating the trustworthiness of that website. The more ‘checkmarks’ a website receives, the higher the possibility of showing up favorably on search rankings. 

Of course, these votes of confidence aren’t just automatically tallied once your client’s link shows up on other websites. Content must also be credible and relevant for link building to be effective.

Google can't yet make a qualitative decision about a website. It can tell what it's about but can't tell if it's important or useful just by reading the site. One of the main factors it uses to determine importance is backlinks because these act as "votes of confidence." If it trusts the sites linking to you, you get a portion of those referring sites' trust. It's just that simple.

Jens Rhoades, Founder at Floodlight SEO

Let’s face it—Google’s algorithm is constantly evolving, and there’s no one way to guarantee a high search ranking. However (as you know), excellent and relevant content is the way to go. 

When it comes to link building, this factor is even more critical as other web sources will likely link to your client’s content if it’s credible and informative. It also makes link outreach easier when you are working with high-value content.

Rich, relevant content and trustworthy links are an excellent recipe for ranking success.

Rhoades further explains, “Link building effectively moves people up the rankings. Even with new changes to the algorithm which focus more on user metrics, backlinking is still the biggest lever in the SEO arsenal.”

Is Link Building Really Worth It?

Modern search systems still use backlinks as a signal of authority, but the emphasis has shifted: relevance, editorial context, and link quality now trump raw volume. That means your link programs should prioritize topical relevance, natural placement, and measuring business outcomes (referring domains, organic traffic lift, and conversions), not just link counts.

Link building may seem like extra work, especially when you’ve already got a lot on your plate. While it may seem time-consuming, link building often pays off in the long run and helps your clients stay one step ahead.

If you’re still on the fence about why you should build links for your clients, consider that:

Link Building Improves Search Ranking

It’s no secret that Google favors content that aligns with its E.A.T. acronym.

A high volume of backlinks from credible sources gives Google a thumbs up about your client’s content, which makes it more likely to show their website on search rankings.

And the data backs it up. The first website on Google’s search page has 3.8 times more backlinks than other search results. Putting in that extra effort to create excellent content and strategizing link-building programs will increase your client’s keyword ranking over time.

Following SEO best practices is the way to go, but don’t forget to remind your clients to remain authentic to their quirks and personalities. Showing personalization lets your client build a personal brand while staying true to themselves.

As Jill Robb, Chief Revenue Officer at Origin, says, “While an understanding of technical SEO is obviously required, the best link builders I know have great PR and content writing passion–not technical passion.”

Link Building is a Tangible SEO Metric

The great thing about link building is that it’s easily trackable and will show a substantial growth or decline. If you’re not sure what type of SEO metric to incorporate into your client’s monthly report, here are a few ideas:

• The number of new backlinks generated per month

• The number of unique domains linking to your client’s content

• Average monthly cost per link (for paid placements)
  

As Robb describes, “Historically, backlinks have always been included as an important part of SEO, with their importance only increasing in value as a quality metric. From an impact perspective, high-quality backlinks are key to moving the SEO needle.”

Over time, track historical trends to understand what keywords and links work best for your client. Not in the mood to manually track all that data? Use an automated SEO reporting tool to efficiently provide the information your client needs.

A Healthy Inventory of Backlinks Builds Credibility

Credibility is non-negotiable when establishing your client as an authority in their industry. Not only will it affect their search rankings, but it also trickles down to other key metrics such as conversion and referrals.

Backlinks build the credibility of a website to rank for the industry. As long as they are done carefully, with thought and relevance, it adds a lot of credibility to Google to rank for competitive keywords in verticals.

Peter Magee, Managing Director at Significant Digital

When reputable sources backlink to your client’s website, it reassures future customers that your client’s brand is trustworthy. In addition to increased website traction, this translates to real-life actions such as store visits and in-person booking appointments. 

As Matthew Cernik, Head of SEO at King Kong, adds, “The improper use of backlinks can cook a website. The list goes on: low-quality referring domains, keyword stuffing, unnatural backlinks, unrelated domains, poor anchor text usage, and poorly developed content. You can hurt your rankings if you don't know what you're doing.”

Link Building Increases Your Client’s Confidence

It’s great to build the client’s name through the internet and get them featured on relevant sites. They get excited to see a blog written and getting featured. As an agency, we like to see the growth in rankings, exposure, and traffic that the website gets from various keywords due to the backlinks.

Peter Magee

As your client’s backlink portfolio grows, so does their brand visibility. This exercise increases website traffic, word-of-mouth referrals, and brand recall.

On the softer, ‘people’ side of things, this reassures clients that their brand is meaningful and has the potential to grow further, leading to positive feelings towards their link building strategy and even the ROI of your agency’s services. 

Your clients are passionate about their businesses and love to see that customers love them, too. Often, your clients have built their business from the ground up, and aside from being a financial investment, it’s also an emotional one. Therefore, credible link building is a pat on the back for your client working hard in the background to grow their brand.

As Christopher Bailey, Website Design and SEO at D2 Branding explains, “Quality backlinks are essential to SEO to help build value for a website and grow the online footprint. It is important to not only focus on building quality links but also to monitor all backlinks to remove low-quality links.”

Bailey goes on to describe, “Diversity in backlinks is also important. A balanced mix of follow/no-follow is a smart practice! Backlinks build value. Value brings high-ranking keywords. And high-ranking keywords bring traffic.” 

Link Building Opens Doors to Networking and Collaboration

Collaboration is an overlooked tool that is mutually beneficial for both parties involved. Not only does it strengthen content relevance, but it also leads to new and innovative possibilities.

Beau Walsh, Founder/Creative Director at The Cultural North
notes, “Backlinks are tools that not only improve your search engine rankings but serve as a powerful networking tool to build relationships with other collaborators across the web.”

While link building is an online tactic, it may foster business partnerships in real life. For example, reaching out to a credible industry leader for a guest post may lead to an in-person panel discussion in the future. 

As Andy Hill explains, “An eCommerce business can send products for review by online publications and acquire links this way. A home improvement business can request links from suppliers and reach out to relevant website owners. There's no one size fits all.”

When and Why Your Agency Should Start Link Building Campaigns

As discussed, creating authoritative content is one way to increase the likelihood of securing those highly coveted backlinks and pivoting your client’s brand to SEO success. However, like most things, an active strategy is needed if you want to hone in on those opportunities.

Your agency may face particular situations where it’s a bit more challenging to rely solely on generating organic content that may or may not result in backlinks.

Here are a few situations where this may happen:

New Websites

If your client is starting a new website, you’re probably hyper-focused on building their social media presence, increasing brand awareness, and putting all those foundational logistics in place. It’s much more challenging to secure backlinks if your client’s brand hasn’t yet gained authority. 

In this case, actively pursuing backlinks can improve your client’s search ranking and open up valuable networking opportunities and alliances.

High-Quality Content With Minimal Links

We’re sure you’ve been in the situation where you created a top-tier piece of content that hasn't generated any traction. After you’ve done the heavy lifting to make that piece, it’s time to focus on disseminating it to the right places. 

In these situations, actively pursuing backlinks can bolster website traffic and give your content the visibility it deserves. Just one backlink can launch your client’s content in a significant way.

Offsetting Low-Quality Links

There’s no digital realm without spammy bots, unfortunately! This also spills over into backlinks, as many bot-like sites will create ‘toxic’ links for malicious purposes. 

To offset your client’s backlinks getting caught in the tornado of low-quality links, manually pursue backlinks to improve the quality balance. This will allow your client’s content to shine without being bogged down by unnecessary noise.

Competitive Metrics

If you’ve meticulously monitored the competition and noticed they’re gaining high-quality backlinks faster than your client, it’s a good idea to take a step back and recalibrate. That’s where actively pursuing backlinks comes in. 

This tactic adopts a more aggressive stance when trying to outperform the competition and uniquely position your client’s brand. It’s also an opportunity to strategically shift your client’s content above the crowd and into high-quality circles.

By incorporating active and passive link building strategies, you’ll position your client’s brand favorably and closer to SEO success.

Quality vs. Quantity– The Great Link Building Debate

It’s a common dilemma. On the one hand, you want to show your agency’s efforts by having an impressive backlink KPI when you send that monthly SEO report to your client.

On the other hand, securing those high-quality links can be a bit more arduous. Even if you secured one fantastic backlink in any given month, your client (or even the senior management they report to) might focus only on that singular number rather than quality.

So, the question remains: Is quality or quantity more critical for backlinks? Here’s the answer!

Prioritize quality over quantity. A large volume of backlinks is ideal only when they are high-quality.

Furthermore, don’t underestimate the power of just one credible link!

It can take only one website to tip the balance of the scales and make Google sit up and pay attention. It has to be a very authoritative site, but nevertheless, it's not always about quantity.

Andy Robson, Agency Director at Squidgy.

That one, targeted outreach will make a difference over a sea of low-quality backlinks. Take the time to strategize effectively and pursue suitable types of backlinks to make sure you're aligning efforts to keywords and link that support the right keyword search intent.

Andy Hill, Managing Director at Distribute Digital, further describes, “A poorly executed backlink strategy can either have no impact, improve rankings and traffic for keyword types with no commercial intent that does nothing for the end sales figures for the business or worse, it can backfire.”

What Happens If You Do It Wrong (AKA The Dangers of Bad Backlinks) 

The competition is stiff and can result in all types of tactics (both ethical and unethical) just to stay on top of those search rankings. However, taking shortcuts or trying to outsmart the Google algorithm certainly doesn’t come without consequences.

There are a few potential consequences of using black hat SEO techniques, the most notable of which is your website being penalized by Google. This means that your site will be downgraded in the search engine results pages (SERPs) and may even be removed from them altogether. 

To put things in context, a few examples of poor backlinking practices include:

1. Utilizing Link Farms

Link farms are websites that are solely created to increase backlinks, including some directories and websites that aren’t related to your client's content. Users may sometimes pay for placements on one of these websites to increase backlinks.

2. PBNs (Private Blog Networks)

A PBN is a network of websites used to increase the ranking of a website created to make money. These networks usually consist of expired domains that have preexisting backlinks. The problem with PBNs is that they're often low-quality, spammy websites.

3. Spammy Blog Comments

Blog comments are an easy way to get backlinks, but they're not always practical. This is because some blog owners will approve any comment just to increase the number of comments on their posts, regardless of the quality of the comment or whether it's relevant to the post. In addition, many blog comment sections are now moderated, which means that your comment may never even be seen by the blog owner, let alone approved.

4. Links from Sites That Have No Content Relevance

To avoid penalties through overt tactics (such as link farms), some users may attempt to acquire backlinks to more legitimate-looking websites that don’t necessarily have content relevance. This tactic may seem like a good road, but Google’s algorithm is intelligent! If there's no logical reason for your client's accounting firm to have a link from a blog about children's toys, Google will sniff that out.

5. Paid Links

Paying for backlinks is against Google’s guidelines. If you're caught paying for links, your website could be penalized. In addition, paid links often result in low-quality websites that aren't relevant to your client's content.

These are just a few examples of black hat SEO techniques you should avoid if you want to maintain a high-quality website that generates traffic and sales.

The SEO race to reach the top of search rankings is competitive, but don’t lose it by resorting to desperate measures.

What Are Link Building Tools & Why You Need One

Link building is one thing, but what tactics are involved? An effective strategy includes:

• Creating relevant and informative content that other credible sources find tremendous value in

• Reaching out directly to authoritative sources for backlinking and networking opportunities

• Collaborating with other industry leaders for guest features on blogs and other related marketing collateral 

But what if you need more support to keep track of those backlinks, streamline networking opportunities, and monitor competitor backlink performance on a larger scale?

That’s where a link-building tool comes in.

Think of link building as an agency-focused SEO tool contributing to your client’s overall marketing success. Depending on the link-building tool, there’s a range of capabilities that include:

• Keeping track of competitors

• Identifying broken links

• Creating alliances with other businesses

• Finding influential websites and contacts

• Identifying new opportunities to capitalize on

Not all link-building tools are created equally, though. Like most tools, some have specialization in one particular area, while another may have a broader scope.

From link analysis to competitor monitoring to outreach processes, there’s an SEO tool that specifically meets your client’s needs.
