Global Meta Data and Titles

[DTOSI]

I am working on an e-commerce website with Volusion. I have 1 main keyword that I am really trying to focus on for my home page. Last week I was in position #7 for this keyword, and I have never been off the first page of Google for it. Using Volusion you can Globally set a Title and meta description for any pages that do not already have a  title or description. I noticed my Global title had the same keyword as I was using for my home page and thought that, that might be taking away some importance from my keyword, so I changed the Global Title to a different keyword.

When I looked at my SEO moz rankings today, which crawled last night it said My keyword was #24 on Google. I checked and as of now I am in position #11.

Like I said before, I have never not been on the first page for this keyword. Does anyone think that changing the Global title may have been the cause for this??

If that's the only change you made, yes I would say that it the most likely cause.

Hey thanks for the response. I am back at #7 so I guess it was just temporary. But don't you think it makes sense that using the same keyword in the Title for the rest of the site would take away importance from the home page??
