To expand your ads and show people more reasons to click, add extensions. Extensions add useful business data below your ad—locations, additional links, prices, and more. For that reason, extensions are recommended for just about every advertiser using text ads on Search.

This article lists the various extensions you set up yourself (“manual extensions”), and when to use them. For a list of extensions that may show without set-up, see About automated extensions. For general information about extensions, start with About extensions.

Before you begin

Keep these best practices in mind as you choose and set up your extensions:

• Use every extension relevant to your business—extensions are free to add and they’ll only show if they’re predicted to improve your ad's performance. For more information on when extensions show, see About extensions.
• Consider adding 4 or more extensions. For example, you could add sitelinks, callouts, structured snippets, and one additional extension of your choice.
• If it makes sense for your business, create extensions at higher account levels (for example, at the account or campaign level, when available).

Select extensions based on your goal

Select your extensions based on your primary advertising goal. Here are common advertiser goals and the extensions that can support them:

Goal: Get customers to buy from your business location

If you want to direct people to your physical locations (like stores or restaurants), here are extensions you may consider:

Location extensions

Encourage people to visit your business by showing your location, a call button, and a link to your business details page—which can include your hours, photos of your business, and directions to get there. If you want customers to visit your business location but to call a centralized line (rather than specific locations’ numbers), use call extensions with your location extensions.
