Don't ever use SEO hosting, it's like screaming at the top of your lungs and telling Google that you own a PBN.When building a PBN, you said above that separate hosting is beneficial. Do you recommend SEO hosting, or individual hosting accounts as being safer?
Also, how much do you need to spend on each domain purchase?
What's the best way to manage all the sites (posting etc)?
and lastly, how many sites to you need for a low-medium competition keyword, for example?
I suspect the ranges of 'SEO' hosts are under watch by Google, just reasonable suspicion.
Different hosting accounts, and read up on the CloudFlare thing I posted if your PBN is small and you can manage that.
Depends on what you're targeting, I always make sure that my domains were never used for PBN's, never purposely built links, nice TLD (.com/.net/.org), PR3+ and DA/PA 40+, so I spent anywhere from $50 onwards, $50 is probably the least I've spent on a domain with those specs.
I have a macro that takes a spintax, spins it, posts. I had my virtual assistant create it, so I don't really want to share it to the public, hope you understand.
10-20 should be fine, again, more or less depending on the quality of the websites that you are using for your PBN.
