Review on Concurra by Ray Sheptock

It's very powerful software which does exactly what you need it for - optimizing your site! I've used other similar softwares before but this has many more features than any others in its class (including Google Optimizer). The support team works hard at solving issues quickly and efficiently. There are some downsides related with browser compatibility as there can be occasional problems when using Firefox or Chrome browsers so make sure they're up to date if needed. We were looking for something simple yet robust enough solution where we could easily create different versions of our landing pages without having too much technical knowledge about how things work under the hood. With concurra we managed to drastically improve CTRs while reducing bounce rates by 70%.
