If say you have 3 high PR sites and then these link to 50 sites to get them a decent PR, and you use these 50 decent PR sites to help you rank in the following style: PR6 - Site 1 - Your Site Site 2 - Your Site Site 3 - Your Site Site 4.. - Your Site Site 10 - Your Site PR6 - Site 11 - Your Site Site 12 - Your Site Site 13 - Your Site Site 14..- Your Site Site 20 - Your Site PR6 - Site 21 - Your Site Site 22 - Your Site Site 23 - Your Site Site 24..- Your Site Site 30 - Your Site Is this a link farm? Is it easily detectable? How many PR6 seed sites would make the difference between it being obvious as a link farm and not being obvious? Thanks
It may be risky interlinking any of your own websites too much. I would only do this if those websites are disposable. Don't do this with any important websites. You can probably get away with just temporarily linking to those other websites. Then remove those links when the rankings are built up. It doesn't really matter if it is a link farm or not. It matters whether it is against Google's guidelines/rules. I don't know if it is technically against the rules, but if someone reports you, you may get penalized. It doesn't need to be detectable to the algorithms. It's up to you if you want to play it safe or try to take short cuts that could result in penalties.
Its easy to identify link farm. The link page created only for the link exchange and they also not maintain any quality. Lots of links on the link pages. Yes more than 50 links.
