Testing platform Optimizely has added an ability to integrate external behavioral data, giving users a more complete view of test impacts. The new feature tracks the tests received by each individual and then ingests data from other systems about their behaviors. This breezily assumes that your other systems can give Optimizely a personal identifier to tie everything together. Easier said than done.

But don’t abandon mobile just yet. When you take non-video ads into account, it’s still king: eMarketer reports mobile will account for $87 billion in U.S. media spend this year.

Oddly enough, marketers rate selecting marketing technologies as the thing they do best.
