If i have something in an iframe will it end up getting cached? There are no links pointing to the page inside my site, just a php page as the source of the iframe.
Read this http://www.google.com/support/webmasters/bin/answer.py?answer=34445&query=frames&topic=&type= and this one http://searchenginewatch.com/showPage.html?page=2167901 I hope this is what you're looking for.
if you don't want google to index the iframe, set your robots.txt file to disallow it: User-agent: * Disallow: /filename.php I do this and it works like a charm. Now if you want it to be indexed, just leave it alone.
i dont care if those frames are indexed, i'm doing it to prevent a reload of the site when somebody submits to the tool. Much better user experience this way. I don't really feel like doing ajax for all of them, besides this way i can let people put the tools onto their sites easily.
Iframes can be indexed in search engines but as a seperate page, if you don't want them to index use a robots.txt or use a no-follow meta tag inside the page that is loading into iframe. But frames will be shown in google cache as a seperate page and inside your page also.
