The 5 Most Important Extension Types

Focus on these for maximum CTR impact:

1
Sitelinks: Additional links to specific pages. Add 4-6 relevant sitelinks per campaign — alone can increase CTR by 10-20%.
2
Callouts: Short phrases highlighting USPs like Free Shipping or 24/7 Support. Non-clickable but build trust.
3
Structured Snippets: Lists of products, services, or brands you offer.
4
Call Extensions: Adds your phone number. Critical for local businesses.
5
Price Extensions: Shows prices directly in the ad. Great for e-commerce.

Setting Up Extensions Correctly

Best practices for extension setup:

1
Set sitelinks at campaign level so all ads in the campaign get them
2
Sitelink URLs must go to relevant unique pages not all to the homepage
3
Write callouts in Title Case under 25 characters
4
Keep structured snippet values concise 3-10 items per header
