# 10 Type of Google Ad Extensions
## 1. Sitelink extensions
Sitelink extensions add additional links under the main text ad in search. These links direct users to other pages on our site that we want customers to visit.

When we add sitelinks as an extension, follow these best practices:

* More is more: Sitelinks won’t show unless you have enough content on your site for two. You should set up 8-10 active sitelinks in each campaign.
Link-page match: Your sitelink title should describe the page content. No ambiguous titles. And don’t send people to your home-page and title the sitelink “Services.”
* Best performers: Link directly to pages that convert or perform well.
* Our site only: Extensions should go to your website; don’t try to sneak another domain into your ad.
Great pages for sitelinks include contact us pages, testimonial pages, and pricing/offers pages. For eCommerce sites, you have many more options for sending customers to category pages or specifics pages.

## 2. Callout Extension
Callout extensions are short bits of text that appear after our ads’ descriptions. Callouts can provide additional, focused information and are a great way to set ourself apart from the competition. Since we only have 25 characters per callout extension, it’s best to use snappy, impactful phrases. Phrases like “Free Shipping” and “Family Owned” are catchy and highlight unique aspects of our business.

## 3. Structured Snippet Extension
Another way to provide additional information about a product or service is with a structured snippet extension. Structured snippets are limited by a header, which must be selected from 12 predetermined categories, like “courses,” “styles,” or “types.” Structured snippets may not be relevant for every business, as they are only effective if our offerings match the headers. But they are a way to highlight extra information that could convince a searcher to click on our ad.

## 4. Call Extension
Call extensions show our phone number and allow customers to call us directly from your ad. They are an extremely valuable tool because, for many businesses, calls are the goal of their Google Ads. Since call extensions promote the immediate action of making a phone call, it is especially important to schedule this extension to show only during business hours, when someone is available to accept the call.

## 5. Message Extension
Similar to call extensions, message extensions give searchers the opportunity to text or email a business directly from an ad, without calling. It is another way to connect searchers directly to what they are seeking, in an online space increasingly dominated by mobile users.

## 6. Location Extension
Location extensions show our address and hours beneath your search ad. They are critical for businesses that rely on local search traffic and for campaigns where the end goal is to get people to visit our physical location. About 20% of all Google searches and nearly 40% of all mobile searches seek local information.

## 7. Affiliate Location Extension
Affiliate location extensions are a useful tool if our product is sold nationwide. They provide users with information on nearby retail stores that stock your product. Like location extensions, affiliate location extensions are useful for encouraging people to visit a nearby store where our products are sold.

## 8. Price Extension
Price extensions show a carousel of prices of a few showcased items beneath your ads on mobile and tablet devices. It’s a great way for businesses to drive highly relevant clicks to their site. While the transparency of price extensions can result in fewer clicks, the clicks you do receive will be more intentional and more likely to convert.

## 9. App Extension
App extensions feature a link to download your mobile app under your ads. These extensions are smart – if you have an app that is only available on iOS, the extension will only display on iOS devices. App extensions give ads a huge visual advantage over plain text ads. If app downloads are a goal of your campaign, then app extensions are a necessity.

## 10. Promotion Extension
Promotion extensions add a visual price tag below your ad and offer specific details about your promotion. You can run them during specific holidays or year-round, the only limitation is that promotion extensions must include a monetary or percent-based discount. Of all Google Ads extensions, promotion extensions give search ads the highest boost in clickthrough rates, on average, and are a simple way to incorporate any promotions you may have into your search ads.
