"Does adding FAQ schema help rankings?"
"Should I use exact match or broad match title tags?"
"Will longer content outperform shorter content in my niche?"
You know what most people do with these questions?
They Google them. Read conflicting opinions. Pick the one they agree with. And implement it without testing.
That's not strategy. That's faith.
The experiment framework
Step 1: Form a hypothesis
"I believe that adding a table of contents to our blog posts will increase average time on page by 15% and improve rankings for posts targeting 3+ keyword terms."
Specific. Measurable. Testable.
Step 2: Design the test
Step 3: Run the experiment
Make the changes. Wait. Don't touch anything else on those pages.
Step 4: Analyze results
Did the test group outperform the control? By how much? Is it statistically significant?
Step 5: Scale or abandon
If it worked, roll it out across the site. If it didn't, move on. No ego. Just data.
The meta-point
Hear me when I say this...
