using 100% width and height iframe to load a page on top of a potentially keyword rich page. hence all the spider indexes about this page is the anything in the <body></body>.
The answer to that is probably no because if google runs a spam filter on anything it'll be on the keyword rich page underneath the frame - the destination of the url it follows to find the page.
I've seen Googlebot spider the contents of iframes.
Hello toolkit. When you say the above, was the content within the <iframe> part of the site? Or, was it content being pulled from off site? I've not seen Google index anything within the <iframe> itself but I have seen it grab content that resides between <iframe>Alternative Content</iframe> which is where the suggested alternative content goes.
If the page that populates the <iframe> is on site, is that page linked from anywhere else like a site map? That is the only way I can see Google indexing the content.
The content was part of the site, and to my knowledge was not linked to from anywhere else (it was the text for a scrolling marquee which used js to scroll the contents of an iframe). I suppose someone could have submitted the output page to google or have viewed the output page when using the toolbar.
