There’s no excuse nowadays not to be optimizing across multiple channels. There’s heaps of tools available from no cost tools to paid tools and there’s plenty of consultants willing to help you get out there and lead you down a path of optimization.

Just remember though, 90% of optimization is done by people, only 10% by the tool. It’s people that create the optimization strategy, the ideas to test, the segments, the content, the creative and of course, the insights that come from the results – both good and bad.

So how do you know if free is ok or whether you should invest in something a little more robust? It depends how serious you are about optimization. It also depends on what analytic tools you run as well. It depends on what you actually want to achieve.

In my previous post on People who liked this, also liked…, I put forward an idea how to generate “related” products of interest, based on what users were looking at, which could then be automated and re-published back to a site, based on Omniture data.

Having implemented this, we’ve made an interesting observation, which changes one our user assumptions, and I thought it was worthy of a quick posting.
