Around Sept 30th there was a data push/PR/link update and one of our website's most important pages suddenly was dropped from page 1 near the top to the bottom of page three. Last week it dropped again to page 5. Now today it's on page 6 and no longer has a title/description. It's listed only as a url: www.my-site-goes-here.com/important-page-goes-here.htm Similar pages
Any idea what this means? Is it about to get kicked out completely?
Usually it means that Google is about to drop the page out of the index. Often that is because they class it as being duplicate content.
However, in the last few weeks, I see a number of those that appear as URL-only in some keyword searches, and then the exact same URL as a normal result with title and snippet for some other keyword search.
It might be that some datacentres simply have some data missing from the index. I would track those URLs and see what happens to them. I would track it in several datacentres.
See if you can find any datacentres where for the same search, the same URL is returned as a normal result while in others it is URL-only.
