10 SEO A/B tests that moved organic traffic by 10% or more

The short version: Small template changes on large sites can move traffic a lot, in either direction. Test them.

What they studied

SearchPilot runs SEO split tests on large sites and published ten changes that moved organic traffic by more than 10%, plus one bonus result.

Key findings

• Moving the brand name to the front of title tags lifted a retailer's organic traffic over 15%.
• Adding a static price to travel titles cut traffic 7%, while dynamic, live prices lifted it 10%.
• Replacing templated text with unique, human-written content lifted traffic 14%.
• Moving ecommerce product descriptions out of tabs lifted desktop traffic 14%.
• Adding pros and cons to offer pages on a comparison site lifted traffic 50%.

Key learnings

• Small template changes on large sites can move traffic a lot, in either direction. Test them.
• The same idea can win or lose depending on details (static vs dynamic prices).

Things to keep in mind

• Selected winners from a company that sells testing. Losing and flat tests are reported elsewhere on its site.
• Most confidence levels are not stated in the round-up, and results are site-specific.
