To start using this free backlinks checker tool, you only need to enter the URL of any website. In a moment, you'll get the results of your backlink audit, including:

The backlink analysis overview

Right after the scan, you'll see the widgets with the backlink details data. In less than a minute, you'll be able to understand how strong a certain backlink profile is.

The widgets include the total number of backlinks and referring domains. The free backlink tool also calculates the InLink Rank score of the linking page and domain.

Nofollow/Dofollow backlink analysis

Dofollow links boost your search engine rankings — the more followed backlinks a competitor has, the harder it'll be to compete with them.

Use our backlink checker to view the complete picture for any site and estimate your domain rating potential.

Backlink profile health

Why use our backlink checker tool

The most up-to-date index

It is built on the freshest backlink database available to the public. New links and referring domains are added every second, with dead links getting removed. A full database update happens every 4 weeks.

Besides, the smart crawling algo checks more important and dynamic pages more often, so some pages can even be recrawled and links updated every day.

Live backlink history stats

With the Historical Data module of our backlink checker, you can access the info on how your backlink profile changed over time. Augment not just your backlink analysis, but your link-building efforts as well.

Inlink rank score

Like Google's PageRank, SEO PowerSuite's InLink Rank is a score that estimates domain rating and backlink popularity. It shows the importance of web pages, determined by the number and quality of incoming links to the page (both external and internal).

With a high score, you can easily spot the most valuable links in your backlink profile. Similarly, a low rank is a great way to identify low-quality, spammy links you may want to get rid of to secure your organic traffic from Penguin, Spambrain, and manual penalties.

API access for pro users

If you want to monitor backlinks using our index outside of the backlink checker itself, you can request access to our API at a custom pricing. Integrate our backlink index into your dashboard or workspace at your convenience, and get all the data you need. A user with API access will be able to fetch up to 3,000,000 backlinks and use that data in their own analytics dashboards every month.

A beginner crash course for SEO newbies

If you're new to the concept of backlink research (and SEO on the whole) but would love to start building good inbound links, we've prepared a beginner-friendly guide to teach you the essential skills. With this guide, you'll learn how to tell a good backlink from a bad one, analyze anchor texts, compare multiple competitors, and find the low-hanging fruit opportunities for easy link building.
