A forum question that popped up, thanks to Robin Goad @ Hitwise for providing the research.
The table below lists the top 10 search engines in the UK during the same 4 week period. By applying the percentage of UK specific searches to Google UK’s market share and creating a ‘new’ search engine, "Google UK Pages from UK only", it would be the third largest in the UK with a market share of 10.03%, behind "Google UK All The Web" and google.com. This 'new' search engine, consisting of Google searchers only looking at UK pages, would have a market share more than three times that of its nearest non-Google competitor, Yahoo! UK.
