Clicking on the cached hyperlink in the Google search result for my principle pages goes to the Google cache snapshot of the page (the one with the highlighted terms used in the search) but except for the standard Google heading for a cached page, and the search terms used printed once at the top of the page, there is a blank page: no text, no highlighted keywords - even though the link to the actual page is full of text and keyword phrase rich. The Google link to the non-cache page is fine.
Any thoughts? I'd be happy to supply further details. Thanks.
By the way, I wonder if this may go a way in explaining (in part) why except for unrealistic searches using all the terms in the title tag for the page, a search with keywords the page is rich in fails to bring it up (I stop clicking at page 30 in Google).
