Multivariate Testing (MVT) (Score 1)

There's a SCRIPT tag which has been commented-out that uses "offermatica/mbox.js", which is the old name for an Omniture product facilitating Multivariate Testing (MVT) and A/B testing. Although this script has been commented-out, it shows that Capital One is familiar with the technique and likely experimenting on their traffic through other means (e.g., server-side rather than JavaScript). Note that Omniture has been acquired by Adobe, so expect to see this type of experimentation happening more frequently. Presumably, such functionality will be "seamlessly" integrated into their content creation frameworks. See whichMVT.com for a list of vendors.
