Re: Dear Rupert
But personalisation is usually a good thing. If you regularly search for products and all of the sites you click on are for prices then Google would be more likely to show you sites with prices. If you always click on review sites then your results will be personalised for reviews.
If most of the type of results you are looking for are usually on page 3 because it is a fringe topic but has a more popular meaning, this personalisation can bring you niche results back onto page 1.
Also most right-wingers want to see right-wing articles and most left-wingers want to see left wing articles. Pushing results to the contrary under their nose (by those who have better SEO staff rather than better points of view) is not necessarily the job of a search engine. If you want a contrary point of view you can find it yourself - no hand holding required.
