I've been trying to get some solid numbers together to determine how many searches are made with certain keywords in the UK.
My problem is that there is no way of knowing exactly how many searches are made with Google, and the figures I’ve found all base themselves on estimates from other search engines.
For example, the most common method is by using the Overture results. However, this method does not distinguish the difference between “widget” and “widgets” or even “widgeting”.
The other problem is that in the UK Google holds something like 80% of the search market depending on where you look and Yahoo UK only holds a 10% share, which means that there is a big chance for error when scaling up, especially on the smaller terms. Also, Yahoo and Google operate differently in different markets, Yahoo tend to perform better in the financial sector for example.
Google trends working on a scale, and can only give comparisons. Most online tools use US figures. The few paid tools that use UK data get their information from UK ISPs or very minor search engines which means that they are very inaccurate.
Is there any clever method that can shed some light on the actual Google search volumes for exact terms in the UK?
