I have noticed something odd about how my site gets listed in Google. When I do a keyword search (under which I should be listed), I have noticed that I seem to get one of two possible sets of search results. In one, my site is nowhere to be seen. In the other, my site is listed in the top 15. Nearly all other results stay exactly as they were.
(Search for "ketubah" and look for my site "Modern Ketubah".)
If I keep reloading that search, over and over, 29 out of 30 times I'll get the one set of search results that doesn't contain my site. But 1 time out of 30, there I am. What's curious is that only my site (and a few others) under this search seem to be effected -- most of the other sites are always in the results, in the same position.
Does anyone have any idea what is going on?
