Which Majestic SEO metric is more important, Citation Flow or Trust Flow?
First and most important – Beware of domain names with Citation Flow even a little more than Trust Flow because often such domains have been spammed with toxic backlinks and can have Penguin or a manual Google penalty.
Trust Flow is more important, Citation Flow is boosted by spam links, and Trust Flow almost never is. However there is a catch – a sidewide link (possible a silly footer link) from a single website with good TF and lots of inner pages can boost TF up to 30, without the site being actually that good. So websites with high CF and high TF and even both high, are not 100% good ones.
We suggest you look at Trust Flow + Referring domains. For example, Trust Flow 15+, Referring domains 10+ is what we are looking for. This fixes the “high Trust Flow with sidewide links from 1-2-3 websites” Majestic bug. If you look at Citation flow (high CF + lots of Referring domains being spam) and the domain name, you will avoid all spammed domains successfully,
