Google Ads Extensions Explained: Boost Your CTR in 2025

Imagine you see two ads on Google.

The first one just shows a headline and a short description.

The second one not only shows the headline but also extra links, phone number, ratings, and prices.

Which one would you click?

Most people choose the second ad. Why? Because it looks more useful and trustworthy.

That’s the power of Google Ads Extensions (now called Assets). In 2025, extensions are no longer “optional.” They are a must-have tool to increase click-through rate (CTR), improve ad performance, and maximize your ROI.

This guide will explain what Google Ads Extensions are, the types you can use, and how to set them up for success.

What Are Google Ads Extensions?

Google Ads Extensions are extra pieces of information that expand your ad.

They allow you to add details like:

Extra website links
Business phone numbers
Product prices
Customer ratings
Call-to-action buttons

Instead of just showing a simple ad, extensions make your ad larger, more informative, and more clickable.

Example: A restaurant ad could show a headline like “Best Pizza in New York” plus extra links for “Menu,” “Order Online,” and “Find Us on Map.”

Why Use Google Ads Extensions in 2025?

Extensions matter because they:

Boost CTR (Click-Through Rate)
- More people click your ad when they see useful info.
- A higher CTR also improves your Quality Score.
Increase Visibility
- Your ad looks bigger and stands out more.
Provide Extra Value
- Users get the info they need without extra searching.
Lower Costs
- Better CTR + higher Quality Score = cheaper clicks.
Improve Conversions
- By adding links, prices, or phone numbers, you guide users to take faster actions.

In short: Extensions = More clicks, better results, lower costs.

Types of Google Ads Extensions (2025)

Google offers many extensions. Let’s go through the most useful ones for small businesses and advertisers.

Example: An online clothing store ad can show links like “Men’s Shirts,” “Women’s Dresses,” “Sale Items.”

Add short phrases to highlight offers.
Example: “Free Shipping,” “24/7 Support,” “No Hidden Fees.”

Why use it: Helps people know what you offer before they click.

4. Call Extensions

Add a clickable phone number to your ad.
Especially useful for local businesses.

Why use it: Customers can call you directly without visiting the website.

Show your business address and a map link.
Example: A coffee shop ad shows “123 Main Street, 0.5 miles away.”

Example: “Order with Our App – Download Now.”

Example: ★★★★★ “Rated Best Plumber in Town.”

Why use it: Builds trust and social proof.

How to Set Up Google Ads Extensions (Step by Step)

Setting up extensions is simple. Here’s how:

Sign in to your Google Ads account.
Select your campaign or ad group.
Click on Ads & Assets → then Assets.
Choose + Add Asset and select the extension type.
Fill in the required details (e.g., phone number, links, prices).
Save and publish.

You can add extensions at account, campaign, or ad group level. Account-level applies to all campaigns, while ad group-level is the most specific.

Best Practices for Using Google Ads Extensions in 2025

1. Always Add Multiple Extensions

Google chooses the best combination to show. The more options you provide, the better.

2. Keep It Relevant

Make sure your extensions match the ad’s message and intent.

3. Use Strong CTAs

Instead of just writing “Learn More,” use “Get Your Free Quote Today.”

4. Track Performance

Check which extensions drive the most clicks or calls. Keep those and replace weak ones.

5. Combine With Great Ad Copy

Extensions are powerful, but they won’t work if your main ad copy is weak.

Common Mistakes to Avoid

Adding too many generic links (confuses users).
Forgetting to update expired promotions.
Using the same extension for every campaign (not specific enough).
Ignoring mobile optimization (call and app extensions need mobile users).

Real-Life Example: Extensions in Action

Imagine you run a local bakery.

Without extensions, your ad might say:
Headline: Fresh Cakes & Pastries Near You
Description: Order delicious cakes and pastries online today.

With extensions, your ad could show:

Sitelinks: “Birthday Cakes,” “Custom Orders,” “Pastry Menu.”
Call Extension: Call Now: (123) 456-7890.
Location Extension: 1.2 miles away – Get Directions.
Promotion Extension: 15% Off Orders This Week.

Which one do you think gets more clicks? Exactly, the second one.

How Extensions Affect Quality Score and Bidding

Extensions improve CTR, which improves Quality Score.
Better Quality Score = lower CPC (cost per click).
This means extensions indirectly reduce your ad costs while boosting performance.

Final Thoughts: Make Extensions Your Secret Advantage

In 2025, Google Ads is more competitive than ever. Every business is fighting for attention.

Extensions give you the edge by making your ads more engaging, more clickable, and more trustworthy.

If you’re serious about getting more clicks and conversions, don’t just run plain ads. Add extensions that highlight your best offers, guide people to the right pages, and make it easy for them to take action.

Remember: Extensions don’t cost extra, but they can double your results. So take advantage of them today and watch your campaigns perform better than ever.
