Matt Cutts, Google's search engine optimisation rock-star, in his keynote interview with Chris Sherman at the London Search Engine Strategies conference yesterday. The main conference room was full with over a thousand avid listeners and bloggers. The picture shows Linda Evans blogging the interview furiously, see Linda's blog entry of Conversation with Google's Matt Cutts.

None of the other presentations achieved a third of of Matt's attendance, which is not bad for a guy in jeans and running shoes. My panel, Exploiting shopping search in Europe got a tenth of Matt's attendance. Maybe next year.

The trends from Google are personalisation and localisation:

Chris Sherman: Crystal ball time, where do you see Google going in the next 3-5 years?

Matt: Fantastic question, in my own opinion – personalization, and localization. Also if you have your data, you can store it at Google. You can almost start your own business of 5-10 business for free. Google’s ambition to organize the worlds information, this is really where its going

Google desktop is also a huge benefit – no privacy issues. Helps to find old searches – makes things more accessible.

Yahoo's is progressing into User Generated Content with Y! Answers, giving them an edge over Google in certain markets. So, the next step in Search seems to be Social Search where community contribution to a knowledge base and community filtering complement algorithmic filtering of the index.

Overall attendance at this years London Search Engine Strategies was down because UK professionals preferred attending the London Technology for Marketing conference the week before.
