- Low Cost
- Much Lower Risks For Google Slaps
- Takes A Beating - it will NOT adversely harm the Web 2.0 domain, neither will is be penalized by the Big G.
Cons of WEB 2.0s:
- Termination - Much like traditional PBN's getting de-indexed in Google for dodgy practises, the Web 2.0s have similar thing, the platform could delete a portion of your Web 2.0 network which is usually the cause of out-right careless abuse of spamming the platforms internal posting systems.
- If you avoid 'unnatural or spammy' practises, then your are going to avoid termination and the loss of a Web 2.0 private blog network.
