So I'm trying to do some A/B and Multivariate testing with dynamic content (+site wide) and with Googles Experiments... I can't do multivariate at all and site-wide AB testing is more complicated than it should be. Now I'm looking for alternatives. Currently I've seen: convert.com - $140/m for 50k tested/m (Added bonus of GA integration) optimizely.com - $359/m for 200k tested/m (multivariate starts at this pricing) visualwebsiteoptimizer.com - $129/m for 30k SiteSpect - Contact sales WebTrends Optimize - Contact sales Anyone know of an open source and/or free script to do this? Or atleast different companies that would preferably be cheaper? I need at the very least 30k/month.
