I just saw a page that is different each time it is viewed.
I noticed a page that ranks well all over AV, so naturally I checked out the source code. The META TAGS are different each time I look at it! I looked at it with this tool where It says: SEARCH ENGINES, see what they see, that I use when I want to see if cloaking is used and it just keeps changing the keywords and title no matter how many times I look at it--I can't see how it is done. They have lots of links to their other pages at the bottom, but the page always looks the same, except for the META TAGS. I never did find the page that is actually listed in the search engine. Anybody familiar with this?
