My Research When Examining EZA and NoFollow Tags
BUT IT'S OK READ ON
They do not put the "no follow" tags in the header. They put the "no follow" tags on the links within their site in the <a href> tags.
This does not include the links in your Resource Box so all the rumors are not true.
EZA still gives well written articles effective backlinks, and great traffic.
I hope this helps all you worried folk like I was.
PS my PM system is broken. Sorry I can't help anymore.
