Cloaked / Redirection Links Example

Definitive list of ways websites don’t return a reciprocal link

[irldonalb]

Hey,

I’m introducing one of my staff to link building. But I’m aware some of the ways websites cloak or disguise links:

Redirection of Links

JavaScript Links

Links from pages with No PR

Cloaked pages

Page with no Google cache

rel="nofollow" tag

Did I leave anything out?

Has anyone a definitive list of ways websites don’t return a reciprocal link. Or a WW thread with some examples or ways to detect these links.

Thanks
Donal

*Did I leave anything out?*

Robots, metas and .txt.

May want to browse the Link Dev Library.

Here's a good one:
