Alrighty, we haven't talked about disavowing in awhile, so here goes!
This is coming from a client that is a publisher who used the toxic domains report in SEMRush and wants to start disavowing domains. These are not bought (to my knowledge) links. I am in the camp that Google ignores bad links and that disavowing in 99% of the cases do not work, and should only happen in manual penalties or something else drastic.
However, the CEO of the publisher is intent on doing it. Should I be concerned about disavowing 110 domains? This is a over a hundred thousand links. For reference, I use Ahrefs and I filtered to domains with DR0 and 0 traffic with more than 500 links per domain.
A little more background - we had them set a few of their child sites to nofollow because it was giving PBN vibes and we saw positive results.
