FAQ Frequently Asked Questions

  What should I look at - Ahrefs Domain Rating, Moz Rank, Domain Authority, Citation Flow, Trust Flow, SEMrush Rank, SimilarWeb or Alexa Rank?
None of the metrics are infallible. They can all be manipulated. However, it's tougher to manipulate them all. So the ideal way is to use all the metrics together. If a domain has a high Trust Flo, but a low Domain Authority, you should research some more into it. The same goes with Ahrefs Domain Rating. The SEMrush Rank & SimilarWeb metrics should be used only for domains with organic traffic.
