A large part of any good SEO’s work is keeping up with the latest developments at Google and watching where they are going in the future. All forward thinking SEOs are also working more and more with social media optimisation, as it is becoming known.

In the last couple of weeks, you may have become acquainted with iGoogle, which is the new default start page for your Google browsing experience. The service itself is nothing new, with its (less catchily named) predecessor Google Personalized Homepage having been available since 2005, but the search giant is now really pushing this idea.

Suggested content for your iGoogle is selected according to your browsing habits. This can be hit and miss; for example, if you say that you are interested in sports, Google assumes that this means basketball, baseball and the NFL.

One thing that people of a nerdier disposition (like us) have always enjoyed about iGoogle is that it encourages developers to create applications, rather like Facebook. Very recently, Google has modified the interface to include an “update” sidebar that shows users what their friends are up to. Rather like Facebook.

This second point is important – alongside traditional search, Google is looking more and more at the social aspect of the internet. The marketing implications of this are pretty big. Social newsfeeds like that in Facebook are a fantastic form of viral marketing – seeing that a friend has done something encourages other people to have a go too. This mainly benefits sites that make an effort to include good content that actually adds something to the internet.

Google is stepping into the world of Social Networking again. After the mixed reception to Orkut (which is, oddly, the most popular Social Networking site in Brazil and India), this time they want to do it right… basically, by mixing whats good about Google and Facebook. This is one to watch.

PS. While searching for images to accompany this post, I came across this. Oh dear.
