The ability to do multivariant testing via campaigns and know the impact of making content changes before we actually make the change. I also like that SiteSpect doesn't use a javascript tag so there is no content refresh or a page flicker.

In house hosting ability is a huge plus for us, as it makes it transparent for the user and theres no "flashing" as it's not javascript based. Stats/Analytics are great and very detailed and every researcher will love these. Very powerful when using regex. You can basically change anything in your sourcecode. Excellent customer support with very fast reaction times and always helpful solutions. The staff are all very friendly, likeable and very easy to talk to as we got know each other at one of their events. They listen to tips from their customers and try to make the tool better with every release.

SiteSpect is a real partner to us. More than just a provider of a tool. For us that is really key, next to their awesome tooling which helped us boost our internal CRO process.
