I'm looking for opinions on the Google Website Optimiser - have you used it? How did you find it? Was it easy to use? Was the data valuable? Would be very interested to see the opinion of anyone who has also used another tool for A/B testing, and how GWO compared to it.
I've used it and do recommend it. It's very good - and free. The only thing is that your pages can get quite cluttered with G's codes. If you have G's Analytics and conversion tracking codes, you'll have to be sure they each go in the right place. It's not really a negative, but it can get confusing : )
Google is notoriously known for it's strict policies. If you just mess you website unknowingly then Google won’t even index your website because every website has to strictly follow the Google rules and this is where this tool shines in full glory.
