10. Ubersuggest
Ubersuggest Free SEO Tool for Bloggers (Backlink Checker and More)
Ubersuggest is often used as a free keyword research tool (though it now has hilarious restrictions on its free accounts). The primary use I recommend it for today, is for when you’re looking into building backlinks to your blog. You can enter a competitor’s URL from within your blog’s niche, into Ubersuggest to do a competitive analysis and see which websites are linking to them (along with each website’s domain authority). This could give you some great insights into what websites you might want to reach out to and pitch for a guest post, or suggest some sort of win-win partnership.
