An As-Seen-On pretty much anybody can do.

I've been seeing this on Clickbank sites a lot.  It looks impressive at first glance.

haha, that's pretty good, will have to think about using it.

Hehe, to the average punter that would be rather impressive. Wonder what affect it has on sales though.

Made me chuckle seeing that. But depending on the demographic being targetted by the site I would imagine that graphic could be quite effective for garnering user trust.

One affiliate site does this with credit card logos and it says something like: "The merchants are accepting these cards:"

I do that Ras. Makes a site look real.

HA great idea.  For thin lead gen sites its normally quite hard to think of any legit logos I can use, will try this.  Do you think I can add an Apple and Samsung logo as well?  I've viewed my sites on both those brands of computer.

Make sure you name the logos something other than what they are.  (1.jpg instead of "google.jpg")
