Forum Moderators: phranque
Maybe I'm missing something here, but it seems like if they gave everyone extra credits when they signed up and a 1 to 1 exchange rate that the system would never be able to use the pool of credits that builds up. In other words there would always be more credits than could be spent...and the number of extra credits would just grow and grow...
Am I missing something here?
About a month ago I've published an article on that very topic (it covers the exchange ratio issue and some others as well) at SitePoint (article 1211). If you need help trying to evaluate a particular case - feel free to PM me and I'll provide whatever assistance I can
In other words - they work fine if
1. implemented properly (by owner)
2. used properly (by member)
And there are people who capitalize well on those selective few that meet #1 requirement above.
Naturally there were static backlinks to my own widget sites, all of which got a PR 3 or 4.
As for how to account for the free impressions... I run the widget exchange site, and some of my own widget sites on the widget banner exchange show banners but have "suspended" accounts and so do not use up their banner credits.
I have heard that banner exchange programs went out of fashion a long time ago. But people are still willing to pay me good money for extra impressions on my exchange program - for that they get highly targetted customers interested in widgets, and the CTR is about 1:100. And can anyone put a price on a PR5 site that almost instantly gives your new widget sites a PR4...? :-)
