Does Google allow server-side PHP bot detection for Flash web sites?
Posted on 2010-09-13
I have a Flash-based home page with HTML body pages. Previously, I simply wrote out the text and links of the Flash page inside of a <NOSCRIPT> tag so that the search engines could index the content. I recently discovered that the search engines do not pass as much (or any) authority (PageRank) to links within a <NOSCRIPT> tag. As a result, none of of my body pages are receiving a PageRank, even though the home page has a high PageRank.
I am contemplating detecting search engine bots with PHP and writing out an HTML page (with no <NOSCRIPT> tag) for the search engines, and the Flash version of the page for normal visitors. This is not an attempt to mislead the search engines, as I will be writing out identical content. I'm simply trying to get the content of the site properly indexed with the links passing appropriate authority to the HTML-based body pages.
Does anyone know if Google would frown upon this approach? It's certainly doable, but I don't want to do anything that may penalize me with Google, or otherwise harm my rankings.
