I find this interesting: Our #1 money keyphrase has recently dropped from the #2 position (behind a Wiki) to position #5 out of 441 million pages. This happened about a week ago. The amazing thing is that it has not affected our CTR or conversions.
The four sites above our position: A Wiki, a dictionary definition, a university faculty page, and a page of articles on the subject from Entrepreneur Magazine. I am of the mind that the reason dropping to #5 has made no difference in revenue is that the 4 sites above mine only provide descriptions of what we actually do. The searcher reads the top 4 descriptions describing what they need until they get to us (#5) where our description tells them they can actually get what they need by clicking on our link.
Has anyone else experienced SERP position drops without suffering loss of traffic? Or, is my experience 'different'?
