How does google treat dynamically generated content on a page?

I'm trying to find information on how google treats dynamically generated content within a webpage?  (not dynamic urls) For example I have a list of our top 10 products with short product descriptions and links on our homepage to flow some of the pagerank to those individual product pages. My developer wants to make these top products dynamic to where they switch around daily. Won't this negatively affect my seo and ability to rank for those keywords if they keep switching around or would this help since the content would be updated so frequently?

If by "switch around daily" you mean you'll be using the same 10 items, but changing the order in which they appear, I wouldn't worry all that much about the SEO effect of it.

If you mean that you'll be changing the 10 products that show, my concern would be less with SEO and more with UX. If I come to a website and see Items A-J are the "top 10", seeing items K-T as the "top 10" the next day or any other time would lead me to believe that "top" doesn't actually mean anything.

So say we have 20 top products but can only fit 10 on the homepage. And we rotate those top 20 products daily. The goal was to have the keywords on the homepage at all times, but if they're rotating around I feel like that negates the seo purpose. thanks!

Your homepage should have static text content that gives an overall description of the entire site, adding this dynamic content is a good strategy.  Just make sure your random generator shows all products equally, or you might have some that never show.

ok thanks,

And don't be surprised if the rankings for those products fluctuate wildly, as you are essentially giving and taking away good pagerank from your home page on a daily basis.

Maybe you could have a drop-down div to "see more top products" or something?

Right, that's what I was worried about. Good idea. Thanks!
