I'm baffled and turning to you guys for help.

We have a specific page or product rather that was crawling up the rankings slowly as we did some natural link building.

Now, however the page shows up as a 404 Page but still under the correct keywords. Not only that, the link that it goes to changes almost everyday to a random product link that doesn't exist.

If you search for "10FT Trampoline with Enclosure" (Google.co.uk) and go to page 2 or 3 and look for the playtimes.co.uk domain, you'll see what I mean.

So, the URL it links to is changing on a daily basis - it's always a dead link and it always has a 404 Title, yet it's still showing up under our targetted keywords.

Does anyone have an idea as to what's going on?
