I know frames aren't good, but are they bad?

[Max_powers]

About 3/4 of my website includes frames from the Amazon aStore, but the pages also have at least 500 words of content on them each. I understand that spiders aren't too good with frames but will search engines punish my site for having them or just disregard them?

Thanks in advance.

I've found no evidence that a site will get punished for using frames - but google will only read the framed link, not the content of it. So the page need its own on-page content, otherwise pages will be marked as "duplicate content".

I would definitely use both title and a paragraph in the iframe-tag to describe the content, to avoid the duplicate content issue.
