Hey guys, I'm new on the forum. I've just learnt about PBNS and WEB2.0 links. So please bear with my dumb questions. Here's my question : I have 4 quality websites with blogs. They pretty much all have links pointing to the others as their content is related. 1- Is this considered black for google ? Is it somewhat a "PBN" ? I have also created a couple of web2.0 with legit content (1 or 2 pages each). It is in the intent of creating links so I guess it's very greyish SEO. 2- Should I use a VPN when creating those ? 3- Should I plug those Web2.0 to webmaster tools and if so, should I use a vpn and multiple gmail accounts ? And finally : When building links, I try to have a good ratio of follow and no follow, good anchor text ratio and I use mostly guest posting (I don't pay for links yet), commenting and quality directories. 4- Is there anything else I should use ? 5- Is it worth it buying links from high PR site if they are not in my language (I'm french) ? 6- How safe or unsafe it is to buy links from trusted sources ? I get that SEO in essence is not entirely white but I'm trying to be very clean and safe while still allowing some grey hat seo here and there. Many thanks.
