I am just wondering whether links from a logo will benefit my site in the same was as a text link would? Do they count at all? If so, is the Alt Tag used as opposed to anchor text? A site has just offered to place my logo on their site which links through to my site, just need to know whether to ask for a text link instead…

If you are getting the next best thing which is an image link, than it is ok. Just be sure they include a proper alt attribute for your Logo image. Adding the alt attribute with the image link provides an added benefit.

I’d also look at what is surrounding your image link. There are “outside influences” that come into play when we’re talking about image links and their placement.
