Just put my new site live last Saturday and I have found it has completely different search rankings when Im in two different locations (very similar distance apart).I get position 3 for Sound Plaza for google.co.uk at home and nonexistent search result on google.co.uk at work. The domain for the site is www.soundplaza.co.ukFrom reading this old post it seems that Google uses your Google log in information, but also uses your browser history, cookies and cache to create the right search results. - http://www.warriorforum.com/main-internet-marketing-discussion-forum/147383-google-rank-two-different-computers.htmlThey recommend CCleaner to get 'neutral' search results however I would prefer to have my internet history, cookies etc. Also it would be a pain to consistently do this.Does anyone know if there is a way of browsing the internet with completely neutral search results?If not, does anyone know any reliable free software which can check your search engine ranking? So far I have tried the following quite helpful.http://www.seocentro.com/tools/search-engines/keyword-position.htmlhttp://www.searchenginegenie.com/google-rank-checker.html
Google position changing on different computers

There are several reasons that results move around:Google uses multiple data centers that are not always completely in sync.  Different computers may hit different data centers, especially if those computers are on different networks and use different DNS settings (for example home and work computers)Google uses personalization in the results.  A users search history and click history may influence the results for just them. There are several ways to force Google not to use history for rankings for youpws=0 parameterSigning out of GoogleIncognito browsingGoogle is always testing things.  To figure out if a site deserves to rank well, sometimes they test it higher and see how many people click on it there.  They may run these tests for a certain time period or only for certain users.   There isn't much that you can do to prevent being randomly assigned into these test groups, even in incognito mode.You can remove personalization, but results may still move around for other reasons.  This means that rank checkers really need to check multiple times, from multiple locations to get a good picture of rankings for a single term.The best rank checker is now Google Webmaster Tools. They give you an average position for the top terms for which your site ranks.  The report is under search traffic -> search queries.
