I'm not looking for a precise number, obviously. I'm more interested in a general range. More text means more long-tail and synonym opportunities, but of course you don't want too much copy above the fold, pushing your products down. Maybe you can get away with a short paragraph or two at the top of the page. You can always put more copy below the products, but in a recent SEOmoz e-commerce webinar, the presenter seemed to think that was silly and unnecessary. He even suggested that the algo might intentionally ignore text below products, since it's clearly not intended to be read. What do you think?

Our site has a number of, shall we say, unoptimized URLs. I would like to change the URLs to be more relevant; if a page is about red widgets, the URL should be www.domain.com/red-widgets.html, right? I'm getting resistance on this, however, based on the belief that you lose something significant when you 301 an old URL to a new one. Now, I know that if you have a long chain of redirects, the spiders will stop following at some point, and that is a huge problem. That wouldn't apply if there's only one step in the chain, however. I've also heard that you lose some link juice in a 301, but I'm unsure how serious that problem actually is. Is it small enough that we'd win out in the long run with better-optimized URLs?
