Of late, a certain company's site comes up when I use one of our trademarks and even my own name in quotes (at #2!) in AltaVista, using an advanced search and August 1, 1999 being the start date. When I visited this competitor's link I could not find keywords or a description tag and wonder how it could have pulled it off. Does anyone know how this might be done?<
Well, Jack, here is the most likely scenario. You had a page that was highly ranked. A competitor wanted to be highly ranked. Your competitor thought, that by simply copying your source code they could duplicate your rankings. Then to "protect their work" they probably installed cloaking technology on their server with IP detection.
The way IP detection works is if a search engine spider comes, the unique IP address of the spider is recognized and shown the "search engine page," your copied page (with your name on it), if a normal visitor comes - with a different IP, the IP detection shows the visitor a different page, the "human page," which, surprise, doesn't have your name on it. So, you would show up in the engines, because the page the spider saw had your name, but you wouldn't show up in the page you saw, because, your name is not on that page.
There are some additional ways to test if this is occurring, but the IP cloaking is pretty powerful.
At your service,
