As of August 13th, SERP's (Search Engine Result Pages) have experienced a little shrinkage.  Roughly 20% of the queries thrown at Google are returning 7 results per page, as opposed to the traditional 10 results that we're so used to seeing.  Some may say "Ok, big deal, so what?"  This may cause concern for Web Marketing firms that have their clients ranking with a lot of keywords around the 8-10 position.  Those search engine results will now put their clients on page two of the SERP's as opposed to page one.
