I'm new to Moz.  Just set up my trial campaign, and it had suggested many keywords.  Many of the phrases that were suggested do not contain prepositions. For example, instead of something like "sporting good stores in Chicago" it suggested "sporting good stores Chicago" Today, I looked at the on-page optimization suggestions, which are (of course) suggesting that I remove prepositions from my page to rank well. Well, as you know, that is unnatural to the reader.  But I suspect people are searching in higher volume, leaving the prepositions out.  I know that if I were to search for a sporting goods store in Chicago, I would probably leave out "in." What should I do?  Should I remove all the suggested keywords, and make them readable (which people are less like using in their search?)  Do I go back to all my pages and try to optimize it for a keyword that is natural, but does not include a preposition (such as Chicago sporting goods stores) or should I be doing something else?
