What makes a quality backlink?

[seojake22]

I’m wondering what makes a quality backlink...

The backlink I’m inquiring about is a contest through BestVendor.com. If I take part in their list-a-thon (make a list of apps around a theme, e.g. best SEO apps) I can work in a followed backlink in the description of my list. They have a pagerank of 6 and it seems easy enough.

This is the list-a-thon I'm talking about. Is this a good backlink / is it worth creating a list to get one?

Thanks!

a) page rank on that page, not the homepage. the page rank has to be on the page you are linked on

b) few number of outgoing links on that page, the more links the more the PR gets diluted and spread out

c) no funky sites also linked on that site, casino, adult, pharma sites

d) straight dofollow link

e) anchor text of your choice

f) in content link, not on some sidebar or footer, in the content of the paragraph.
