Hy to all. I am struggle for about 2 years with FREE blogs and free hosts for blogs ( WP and WP mu) I have about 4 main sites and I have behind them about 10-15 free blogs with links. My question 1 is : is worth a big work for searching and setting free blogs or free wp on free domains? For me it is a hard work: searching blogs, sign in, etc, and half of them are down after few weeks and many posts..After 2 years I have only 10-15 stable blogs that I trust , as my back links farm. THEY are good because are on the different IPs.. My question 2 : Do you establish a blog farm ( for back link purpose) on payed domains? How many domain do you have? separate IPs? ( Involve this alot of money) sincerely I am tired in searching blog lists , or to scrape Google for searching free WP blogs ..LOT OF TIME..minimum results. Also I think that on self hosted WP blogs I can put my ad-sense ( not only links) and that type of blog OWN me , but I cannot afford a such diversity of IPS as the free blogs.. also question 3: today i work and develop about 4 projects (affiliate sites) Let say one about money , one about sports ..etc..I must have a blog farm ( with different wp blogs) for every niche ? or it is enough some general blogs with subdomains /subblogs for my niches? first situation involve a lot of domain to purchase for blogs.. any advices? ( and sorry for my poor English) PS : i post to my WP blogs my own script so I do not need to have total acces to WP cpanel or to install wp robot or other scripts..
