I made post earlier today about, and including, my full "http://www.mydomain.com" site name (doh, schoolboy error), and now when I type just "the-stock-market-site.com" into the (Google) search, I see it's been picked up by the SE's; there it is on the first page, complete with a line or two of my post. If anyone looks, you'll see what I mean.
I'm no techie in terms of SEO inner workings, and would dearly love to know - is there any way I can get rid of it from the SE's, and indeed anywhere else it may end up ? How much of a problem is it? My domain name's rather specific, but the KWs not so.
Hope someone can help/advise please?
