I'm thinking of using D7 overlays to present secondary page content to my site visitors. Overlays would be started by links from the home page and overlay on the home page content. However, overlay content is loaded using AJAX and a URL fragment. I am worried that this content will never be indexed by the search engine robots, since they do not read URL fragments and/or cannot load AJAX content. Even if they could, I feel that I would get a lot of fairly duplicate content (every time the content of the underlying home page plus the AJAX loaded pieces).

Can anyone shed some light on this? Is it bad SEO practice to use overlays or do I worry too much?
