A/B testing isn't just for landing pages and button colors.
You can A/B test SEO changes too.
And you should. Because guessing whether a title tag change will improve clicks is... well, guessing.
How to A/B test for SEO
Method 1: Split testing title tags
Pick a group of similar pages (e.g., 20 product pages). Change the title tag format on half. Keep the other half as control.
Wait 2-4 weeks. Compare CTR in Search Console.
Method 2: Content structure tests
Take 10 blog posts. Add a table of contents to 5. Leave 5 without.
Monitor rankings and engagement metrics.
Method 3: Schema markup tests
Add FAQ schema to half your eligible pages. Don't touch the other half.
Compare click-through rates after a few weeks.
The rules of SEO testing
Test one thing at a time. If you change the title tag AND add schema AND rewrite the intro, you won't know which change caused the result.
Use large enough sample sizes. Testing on 2 pages is not statistically significant. Test on 10+ pages minimum.
Give it time. SEO changes don't show results in 48 hours. Wait at least 2-4 weeks. Use Google Search Console to monitor the impact.
Document everything. What you changed. When. On which pages. What happened. Our SEO experiments framework formalizes this process.
