Hi... I'm already on 10 websites for my PBN all high quality, domain expired, article write manually... etc... I want to know how to maintain the PBN at the top of metric like trust flow. I would like to make a facebook and twitter for all of them, this is a good way to do ? But how to manage 10 facebook, 10 twitter ? And probably more in next future. Do i need to go for a tiers 2 and if yes where i need to buy those link ? I will not have enough time to make 100 web 2.0 myself... Last question : What do you suggest ? Improve the quality in the seo way (social sign, link bulding) for my PBN or just add more website, quantity or quality ? Thanks to answer because i don't really know what to do next in short : 10 websites is already a nice amount of work, i can add 5 more soon if i want, but it is not preferable to improve the quality of my existing website (content is good but i didn't work at all on nothing else) ? And if it's preferable how to improve ?
