I think that these seals have little effect. You are better off focusing on usability if you want results.
I'm pretty sure there's statistics that have shown that trust seals do improve conversions. But whether or not there is, I'm confident that it adds to my overall impression on my website.
I know on some searches I'm not #1 - but the sites above me have a faint greasy feel. Either they're harvesting information and selling it, or it's a one person operation - and it shows. Hey, I'm basically a one person operation as well, but I'm as professional as any large corp - and the badge on my website contributes to that professionalism, and thus to sales. People end up doing business with my site *after* they've gone through the top 2 or three results and didn't like what they saw.
