Links for traffic I think are currently the most under rated links out there. Too many people are turned off by things like no-follow. I'd rather have one link on a PR1 page that gets heavy traffic then any number of PR10 links that no one will ever see. Why? CTR & ROI
All PR10 websites have huge traffic. There's only 8 of them in existance...along with some PR10 sub-pages which also have huge traffic. You say CTR and ROI, don't you care about SERPs?!?!
Of course I do, but SERP isn't over rated Either way though, the bottom line IS traffic, regardless of the link, though too many people place too much importance on Page Rank.
