The 16 Best Backlink Checkers – Free 

and Paid SEO Backlink Tools

Today’s search engine optimization relies on building high-quality links. It’s not just about how many people are linking to you, it also depends on the value of each link. If you’re investing in keyword research and great content writing, the last thing you want to do it blow your SEO with bad link building practices.

The only way to know for sure is by using a backlink checker tool that will track your links for you.

Take a look at the top 16 backlink checkers in SEO and use them to improve your strategy:


Official Site

To be fair SEOJet is much more than a backlink checker, it is full-featured backlink software. In fact, we integrate with several of the backlink checkers on this list to ensure you get the full picture of your current backlink profile.

What SEOJet does is take the backlinks that your site already has and gives you a roadmap (we call it a link map) for future backlinks you still need to get in order to beat out your #1 ranked competitors. So technically yes we do report on your backlinks but only so that we can give you all of the backlinks you still need to get in order to take over the top spot on Google.

Using real-time Google data SEOJet creates a link building plan that helps you build out a natural backlink profile that matches other #1 ranked pages. In essence, the software doesn’t just report on what you have already done in terms of backlinks, but what you need to do to get to the top of Google.

One of the coolest features inside of SEOJet is our Competitor Lock report. This report compares your backlink profile to your #1 ranked competitors backlinks for any keyword and shows you what you are missing. The report also shows you the backlinks they have that your site doesn’t have.

Obviously, since I built SEOJet, I am a little biased. Check it out for yourself to see how it can help you get to the top of Google quickly.

Rank Signals

Official Site

Rank Signals offers a lot of the same features as other link checking tools, but there’s one crucial thing that makes them stand out from the others: they differentiate between dofollow and nofollow links.

Their link explorer tool not only displays your link profile data, but also tags the links that are nofollow. Nofollow links are usually not picked up by search engines, so they do not impact your SEO score. It’s important you know which links are nofollow and dofollow because it gives you a clearer idea of the most valuable links in your profile. For example, you might have a hundred backlinks, but if only three of them are dofollow you need to find better places to build backlinks.

What happens to your links once they’ve been posted are out of your control. Pages move. Old content gets deleted. It’s impossible for you to keep up with manually. Rank Signals can help you easily identify broken or deleted links so you can correct any issues immediately.

Like other link analyzing tools, Rank Signals will also help you find spammy links that can ding your rankings. They offer link signals and metrics and will help you compare your link profile to your competitors.

Best of all, they offer a free (limited) backlink checker directly on their website – no signup necessary.

Majestic (Integrates with SEOJet)

Backlink Watch

Official Site

This backlink checker tool is probably the simplest to use on this list because there’s nothing else on the page. Just enter the URL of the website you’re investigating and wait for the results.

The information you receive in return is simple and straightforward. Backlink URL, anchor text, page rank, the total number of outbound links on the page, and whether the link is nofollow. They don’t offer much else for backlinks, nor do they have an option to pay for additional features. It’s a quick, easy backlink checker tool that does exactly what its name promises.

The site does have many ads that make it look a little busier. It doesn’t offer the clean user interface that other backlink checker tools offer. It also takes a little longer for the full results to populate compared to other tools. In some cases, not all information will be available for every backlink (for example, the page rank rata might not exist for all entries).

But on the plus side, it is a highly simple backlink tool to use and it’s 100% free. It’s a great option if you’re tight on a budget or just need basic information (especially for spying on your competitors).

Open Link Profiler

Official Site

This straightforward backlink building tool was created specifically for one purpose: getting trustworthy backlink data.

They’ make it easy – just type in any URL and click the green button. Their tool compared the website’s unique links to their total number of active links (no, it’s not always the same!), as well as links to the website’s home page and the number of nofollow links.

The link influence score is a feature not found on other backlink checker tools. This gives you a better idea of the quality of each link and the impact it has on search engine rankings. The higher the link influencer score, the more impact it has.

Other valuable information includes the type of industry each linking website falls under, the page title and URL, anchor text and link destination, and the date the link was established.

The platform also includes a disavow feature to disinfect harmful links, popular anchor text, pages that provide the highest number of backlinks (laid out neatly in a pie chart), a breakdown of industries that link to a website, the context in which a link was provided (blog, news website, etc), counties of websites providing the link, and the ability to set link notifications.

You can sign up for a free account to access most of these features. There’s also a paid version that gives you premium user access.
