Interesting, I used to use some blog networks in 2012 with great results (I hit a bank with it :>) and I'm doing since then something else, but it turned out that with SEO I can make much more money with my products (I have some small manufacturing company, paid in 100% from SEO :>), so I would lean into something safer as for now I will just play with some big words to test waters again, and in next 2 months I want to do some proper SEO for my industry.
Biggest issue is my time, but surely you have right to create own network.
Thanks for advice.
I will start first with well known blogging sites to test, who knows maybe even my "old" keywords would hit TOP5 :>
So my plan will look like this:
1. Jan 10-15 blogs as T1 (+ some high PR manual links and high PR SeNuke web2.0/profiles, T2: SeNuke + Xrumer + SB + UD + GSA T3: XB+SB+GSA
2. Feb 20-30 blogs as T1
3. March 40-50 blogs as T1
