5 Best Free Online Backlink Checker Tools

With regard to SEO, much has changed in last couple of years, but one thing that remains the same is the backlink.

Formerly, your site would rank higher based on the number of backlinks you’ve gotten, but in 2015 it’s all about how many quality links you have.

Last year, Google’s Penguin algorithm update killed all the private blog networks and devalued the low-quality links. In this tutorial, I will be discussing some of the best online backlink checker websites you can use to check how many backlinks your website has gotten.

Backlink Checker Tools

Why you need backlink checker tools:

When any website links to your site or any page of your site from its website, this is called backlinks. Backlinks used to be one of the most important parameters for high page ranking and better keyword ranking. However with time, Google demoted the priority of backlinks and added more signals to rank a website.

Backlinks are usually categorized in two ways: Dofollow backlinks and no follow backlinks.

When we talk about creating backlinks, we usually concentrate on creating dofollow links. Using backlink checker tools, we count how many backlinks we have created for our site. A good number of backlinks helps immensely in improving the page rank and also the Moz rank of our site.

Following are some free online backlink checker tools that will help you to see all the incoming backlinks to your website. You can select any one of these tools based on your requirements. Some of them offer detailed results while others offer only the number of backlinks, but none of them requires registration or sign up that makes the process quick and easy!

  • Update: SEMRUSH added backlink analytic feature.

Find backlinks to your site with these backlink checker websites:

SEMRUSH: Most popular with multiple features

SEMRUSH is a tool that I have been using for almost two years, and with the new features they are adding, it is becoming a highly robust SEO tool.

Before I discuss the backlink checking feature of SEMRUSH, I must mention that it is not a free tool, but you can use this special link to try SEMRUSH completely free for 14 days.  If you find it to be a useful tool, its cost to purchase is $149.

SEMRUSH has an extensive database that is updated daily, allowing you to check accurately your website’s backlink status.  Here is a screenshot of their main page, where I’m checking the backlink status of my blog.

SEMRUSH Backlink overview report

Note how their domain Overview report displays details such as which TLD’s zone is linking you to the most pages.  You can also find details about the country from which you are getting most links.

You can use SEMRUSH to check backlinks for your website or your competitor’s website.

They also have a backlink comparison tool that you can use to compare your own domain’s backlinks with others, and get a complete report. Here is one such report:

Overall, SEMRUSH is a tool that you should be using right now as your backlink checker.

Here again is the special link that will allow you to try SEMRUSH for free for 14 days. (You can cancel anytime within the 14-day period, and you will not be charged.)

AHrefs: Recommended for link detox

ahrefs link checker

AHrefs is a recent addition that I find to be worthy of mentioning here. It is a paid backlink checker tool, but if you register for a free account, you can get a complete backlink analysis along with an anchor text analysis of your site.

This tool offers a great deal of detailed related to all of the backlinks to your site, and with time you can see how your site links are increasing or decreasing.

Following the Penguin update, if you are hit with negative SEO, this will be a lifesaving tool for your site, as you can get all the link details along with a percentage breakdown of anchor text pointing to your site.

AHrefs is one of the best backlink checker tools on my list.

Check your Backlink using Ahrefs



OpenLinkProfiler is one of the latest additions to the list of free backlink checker sites. This is a completely free tool that allows you to check the freshest backlinks (and all other backlinks) pointing to your site. You can also export 1000 of the freshest backlinks in .csv format. This tool is probably the best completely free option available for checking links to your site.


BuzzSumo Backlink Checker

BuzzSumo is one of my favorite tools for content marketing, and they offer a free version as well as a pro version. The pro version now has an added feature allowing you to check backlinks to your domain or any individual page. You also have the option to export existing links into .csv or Excel format.

Check out BuzzSumo.

BackLinkWatch: Free but not so accurate

BacklinkWatch is one of the most popular tools for checking the backlinks of your blog. However, one feature of BacklinkWatch which I do not like is its use of pop-ups.  Pop-ups, of course, can be closed with the single click, but pop-up ads always turn me (and many other users) off. BacklinkWatch does provide you with all the details of the backlinks of your blog.

Open Site Explorer:

Of all the tools listed in this article, Open Site Explorer is my favorite.  If you want to compare backlinks between two or more domains, Open Site Explorer is worth trying. This tool works best when you have a paid account of SEOMOZ though a free version of this tool is good enough to get you started checking the backlinks of your site and the sites of your competitors.

Link Diagnosis:

Link Diagnosis provides you with different options while checking backlinks for your blog.  For example, if you need a detailed report or optimization, or if you want to check backlinks for a single page or an entire website, Link Diagnosis allows you to do all of this.  It also offers various types of outputs and other features. It is important for you to know, however, that Link Diagnosis works best with Firefox.

    Personally, I use Ahrefs, Open Site Explorer and Backlink Watch. So far, I get what I need in using these 3. But I have to say that I have to give Buzz Sumo and Link Diagnosis a try. Thanks for listing these tools.

  2. says

    I personally use Seo Profiler and Hhrefs. I think Seo Profiler gives u a keen idea which backlinks are really good and means alot for you from Link Influence percentage!
    Backlinks of Competitor as well

  3. says

    How about using Xenu Sleuth for checking your backlinks. It provides a comprehensive report on the health of the links of your site.


  4. Biswas says

    I always use OpenLinkProfiler for backlink analysis. Because it is 80% accurate. I think no tool is 100 accurate.

  5. says

    I would recommend Ahrefs – one of the best tool in the category. Although best is to take advantages through all these tools for different websites. And yeah! paid versions are sometimes a wise decision.

  6. says

    Thanks harsh for this info on different backlink checker programs. I have a question here. When i am checking the backlinks for my website it is giving me different results on different tools. Semrush and Ahrefs results have big difference in number of backlinks. MOZ is showing null result compared to some months earlier when it was showing me the results . Why is this happening ?

  7. says

    Thanks very much for sharing. I’m personally looking for a free/low-cost backlink checker that would specify what backlinks are dofollow. Doesn’t seem like that should be a tough find, but I’m having a go of it. Any thoughts?

  8. says

    I am finding effective back links tools from last couple of weeks and here you go. This is exactly what i needed and especially openlinkprofiler.org. Thanks for sharing this useful content.

      Thanks @Agha for your comment. Ahrefs is top in the class. At this time I’m using SEMRUSH for the same, as they offer many more SEO features which helps me manage everything from one place.

  9. says

    Thanks for this great information. As per my experiences SEM Rush and Majestic SEO are fantastic tools and has all the essential features even in their free version.
