Yahoo have just published a great review of the 2009. It will be online until Dec 30th and makes for some interesting reading.

One bit of information to come out of this are the list of top ten mobile searches. In 2009 they were as follows:

1. London
2. Premier League
3. Big Brother
4. Champions League
5. Katie Price
6. Lottery
7. Weather
8. Mail
9. Cricket
10. Michael Jackson

Although web search is dominated by Google, it is worth noting that in mobile search, Yahoo is a significant player. The top searches make some interesting points about the way that users engage with the mobile web. Typically it is to access small, specific pieces of information: location related information, football (and other sports) scores, the weather and lottery numbers. The Yahoo results bear this out. Yet looking at all searches (both fixed internet and mobile), the results are somewhat different:

1. Big Brother
2. X Factor
3. Job centre
4. Michael Jackson
5. Jade Goody
6. Premier League
7. Swine Flu
8. Katie Price
9. Cheryl Cole
10. Train Times

Looking at all web searches, the focus is much more on entertainment (6 out of the top 10), whereas mobile searches are more information based (7 out of the top 10). It tells us that the mobile web is different. Brands should recognise this, and tailor their mobile web offerings accordingly.
