Google have recently announced that they have recently changed the way that personalised search works.

Previously you had to be logged into your Google account for this to work. Personalised search will now be available to people based on 180 days of search activity linked to an 'anonymous' cookie in your browser.

Find more details about personalised search HERE.

And if you want to turn off personalisation in your Google search results you can find out how HERE.

If you are an expert on search engine optimisation what are your thoughts on how this will impact search results and what challenges that brings those of us who want to appear higher in the search engines?
