What have I missed?
I have been number one with my chosen keyword for a long time, but have noticed a newcomer coming rapidly up behind, and this is now number 2.
I got curious, and started to see how it was worked, and guess what? - the keyword doesn't even appear on the page or in the page code, in fact it only appears once on the whole site, and on a rarely visited page at that.
How can this be, that a page with no reference to this word can feature as the number two SE result out of an 8000 plus result list?
