Today it is the first day of SES London 2013. Lots of things are going on and you will be getting updates from us from London throughout the next three days. If you are visiting SES London, we have some fun things for you. Starting with this: SES Bingo. Richard Kirk provided us with this sheet. Let’s see who has reached ‘Bingo’ first! Make sure you tweet about it using the hashtag #seobingo!
