Steve,

Testimonials should be part of the picture or story. I tried them on a clickthrough and were a total waste of time on another page. I now disperse them through the copy but only at a certain point.

For example when say you are getting to a point where you have made a statement like...

"and we can prove without a doubt abx have created the most effective hair restorer ever..." maybe add some hairy testimonials just after.

They are just better as part of a story rather than having a load simply thrown in.

Position: The eye is always drawn more to the right. Tests have proved that. A good way to increase readership of copy is to have "stop points" . That is where a block or something esle will srtop the reader for a second and force them to read. I tend to put my testimonials at stop points.
