There’s plenty on SEO, but I wanted to roll this back into testing, so I found a great article, “How Do I Successfully Run SEO Tests On My Website?”
I’m going to steal his image here:

After addressing the main points about having control groups and repeating tests, the tests themselves consist of things like:
- Adding/removing blocks of text from the site (yes, removing can help!)
- Adding/removing comment and share buttons
- Adding or removing “descriptive content, images, and videos”
You’ll notice that ranking isn’t the #1 priority (now there’s a weird statement). We are also interested in the number of site visits and stability of traffic performance over time. i.e. how do these rates change when we make any of the modifications above?
