FREE DOWNLOAD – Statistically Significant PPC Testing using Google Math

I recently posted an article about statistically significant ad testing which has been, by far, my most popular post since starting the blog.  In a quest to understand the math behind statistical significance I came across some great information provided by Google.

So, I took their math and created an Excel spreadsheet for a free download.  According to Google this approach is appropriate for percentage metrics like: CTR, CVR, etc.  I hope you find a good use for it.

    Great spreadsheet, Chad. Every PPC manager needs to pay attention to statistical significance in testing, and this worksheet really takes the hassle out of doing the math.

    Thanks for the spreadsheet! We do PPC ad competitions here in the office, and this will be a good way to make sure our data is accurate!
