Google not really ignoring common words?
If you search on google for “photos of snow”:
My website has a hit on the first page. But, google indicates that the “of” is a common word and is not included in the search. But, if you then search for “photos snow”:
The results are different and my site doesn’t show up in the top results.
Therefore, contrary to what Google says, these “common” words are significant in searches.
