Google backlink checker
While this is the most “accurate” backlink checker, it’s only possible to examine links to your own website and it’s not that easy to use.
Backlinks in Google Search Console are the ones Google recognises or has found and may be different from the backlink profile on other tools (in fact, they might be quite different). This is because Google ignores many links if it considers them spammy or low quality backlinks.
Many backlink finders list all of the links they uncover, including links that the search engine algorithm ignores or hasn’t registered.
This is the newest backlink checker on the list and one that comes possibly the nicest interface. It's clean and uncluttered, everything is easy to find and pages are fast loading.
There's a generous free plan that gets you 5 free searches monthly. But you can delete previous searches to free up your credits.

The link explorer tool also has a spam score report which is useful when evaluating link opportunities and determining potential bad links.
Neil Patel’s Ubersuggest
As one of the most visually appealing tools to use, Ubersuggest is popular. And the information is reasonably useful. But what started out as a free backlink checker tool (and free SEO tool) is becoming a gated, paid tool.
It’s free to use for 3 searches a day and I don’t think the information is as accurate as other products on this list. The keyword information tools are certainly not accurate but if you’re on a tight budget, this is a fast, easy-to-use option for checking anchor text, new and lost referring domains, and other quality metrics.
