Which one is best for you?

We explained that after testing numerous options, SEMRush is the best overall choice for features and pricing. It is used by both enterprise SEO agencies, and in-house digital marketing teams. (Try it out here to see why)

That said, at a very minimum, any one of the backlinks and SEO planning tools listed above will help grow your backlinks, analyze them for better backlinks in the future, and help you research your competitors backlinks as well. They all have some rather different and sometimes unique features tailored to different user needs. Seobility is good for quick daily backlink checks, Open Link Profiler offers extensive backlink data and analyses, and SEO SpyGlass, as one of the top overall backlink checkers and SEO planning tools, does it all. 

Yet it might also be the case that no single backlink checker or SEO tool has everything you may need, and using a combination of two or three may leave you better off in the long run. For example, for quick backlink checks, you can first use Ahrefs, because it does not have a daily limit, and then after, you can use Seobility for a detailed exploration of your and your competitor’s backlinks as Seobility provides 400 of the top backlinks per check you conduct. Another option is using Google Search Console, which allows users to view the top 1000 backlinks but provide very limited backlink metrics and analysis. Yet this does not stop you from downloading the results of your Google Search Console backlink check and using the information to conduct a more thorough analysis using another backlink and SEO planning tool, like SEO SpyGlass. SEO SpyGlass is a prime example of a backlink checker that allows users to extract the backlink data from Google Search Console and download it to be analyzed in SEO SpyGlass. It still would not beat the features / pricing balance available from SEMRush. 

Choosing the best backlink checker and SEO tool simply depends on what you want to use the backlink checker or SEO tool for, and knowing this will help you decide which one, or two, is best for you!
