Google Search results are finite. On a mobile phone, the screen is only about 600 pixels high.
This is a zero-sum game. Every pixel you occupy is a pixel your competitor cannot occupy.
Sitelink Extensions are your weapon in this war. They allow your ad to expand from a small text strip into a massive billboard, pushing your competitors "below the fold" (where nobody clicks).

Sitelink Ad (Dominant)
Figure 1: The Land Grab. By adding 4 sitelinks with descriptions, you take up 2x more screen space, physically pushing competitors out of view.
The "Homepage" Mistake
Common Error: Most businesses set up sitelinks that all point to the Homepage (or just slightly different sections). Google hates this. They might not even show them.
For Sitelinks to work, they must offer distinct value. They act as a menu for the user to "Choose their own adventure."
Link 1: "Home"
➡
❌ Homepage (Duplicate)
Link 1: "Pricing"
➡
✅ Pricing Page (High Intent)
Link 2: "Reviews"
➡
✅ Testimonials Page (Trust)
Link 3: "Contact"
➡
✅ Contact/Book Now Page
Figure 2: Deep Linking. Send users exactly where they want to go. This lowers bounce rates and increases conversion.
Don't Forget Descriptions
You can write just the Sitelink text (e.g., "Contact Us"). But you should add the two description lines.
Without description lines, your sitelinks are just tiny blue links. With description lines, they become blocky buttons that take up massive vertical space. Google doesn't always show the descriptions, but when they do, your CTR skyrockets.
Conclusion
If you aren't using Sitelinks, you are bringing a knife to a gunfight.
Fill out every extension Google offers you. Callouts, Snippets, Images, and Sitelinks. The more space you take, the less space your competitor gets.
