From time to time we head on over to that amazing site WhichTestWon to see the latest and greatest marketing tests businesses are measuring and since we’re all geeky about measuring it gets us pretty excited!

The latest test is an awesome one. Why? It’s a B2B company! Many of the tests we see are with consumer-based companies.

So AWeber decided to do some a/b testing with their call-to-action button on their homepage for a week with one simple change, adding the word “Now.”

Version A increased paid sign ups with a credit card by 12%, that’s nuts! So why not test some CTA’s yourself, use a tool like Optimizely to do it and measure your own results.
