Why is there difference in keywords of moz and ahrefs

[ericcampbell1]

Hello, my welding helmets website Helmet Adviser is about reviews and is causing me confusion. When I check my site keywords in Moz it shows lesser keywords and when I check in ahrefs it shows more.  Same is for backlinks. But Moz keywords research is very authentic and i want to rely on it for keywords and backlinks too. Please elaborate for me why is there diff between Moz and ahref, so I can better utilize Moz by understanding what is going on in the background.

Eric,

There are no absolutes in SEO.  Ask me any question and I can give you 5 different good answers for it.

There are no absolutes when it comes to platforms for SEO tools, either.  They've each arrived at their distinct solutions from different perspectives, although they may be trying to attain the same goals.

Experience is the answer.  Using and comparing how the tools provide the answers you're looking for is what make them shine for each of their particular qualities. You have to use them all to understand how to compare them all. There are no shortcuts to that.

Hi - Thanks for posting.

The ranking keywords section of Keyword Explorer is powered by a different corpus than other parts of the tool. Although this keyword corpus is large, it doesn't include all keywords so there may be keywords you're checking elsewhere in our tool suite (like Rank Checker) that have not been added to our ranking keywords corpus just yet.

This corpus will continue to grow, though, and although I'm not able to provide an ETA at this time you may see those keywords included at a later date. If you'd like to track those additional keywords that aren't in the corpus just yet, I would suggest adding them to a Campaign. That way you can continue to track your rankings for them over time.

Best,
