Does Yahoo! scramble results?

[tcady]

Does anyone notice that Yahoo! seems to scramble results a little?

An hour ago I was in the ten spot, an hour later I am at #12, and for the same exact keyword with an S at the end, I am at #1 now, but was at #3 an hour ago....is it just an update occuring while I check things out, or are they randomizing the results a bit?

And howcome results are SOOOOO very different for a keyword string with and with an S at the end....

Are there any stats about wether searchers make products plural or singular more often when they search?

While is is not uncommon for minor fluctuations to occur in SERPs I am seing stable results on many of the sites I monitor, so I don't think Yahoo are randomizing or scrambling their search results.

You can get information on how many uses search with the singular and plural of a word at http://www.wordtracker.com .

Does anyone know of a ticker like the one suggested above *that is free*?? and shows all the real top words, not a screened version.
thanks.
