This video will explore all the different Google ad extensions. To set up ad extensions in Google Ads (formerly Google AdWords):
The various types of ad extensions include:
Structured snippet extensions
Sitelink extensions
Callout extensions
Call extensions
Message extensions
Price extensions
Location extensions and affiliate location extensions

Structured snippet extensionsStructured snippet extensions allow you to showcase your unique products and services. 
When setting up your structured snippet extension, you’ll encounter a list of available categories, such as:
Amenities you offer
Brands you sell
Courses or degree programs you offer
Destinations people can visit
For example, if you’re a university advertising business degree programs, you can include an extension highlighting your MBA program, hospitality management, marketing, or any other relevant degree programs. According to Google, you should aim for four values in each header. So, if you’re advertising business degree programs at a university, you’ll see a header like “Degree programs,” followed by a list of at least four programs.Sitelink extensionsSitelink extensions enable you to include links to different pages on your website, in addition to the main ad link. 
Using the university example again, you can include sitelinks to various degree programs or informational pages on your site. When using sitelink extensions, you must have at least two sitelinks, with a maximum of eight possible to display. On mobile devices, sitelinks appear either vertically or as a carousel. The vertical format is used for top-ranked ads, while the carousel appears for ads below the top ad.Callout extensionsCallout extensions allow you to highlight the unique aspects of your business. 
For instance, if you run a 24/7 plumbing company, you can use a callout extension to emphasize this service. Google recommends making callouts more specific as you move from the campaign level to the specific ad group level. If you’re advertising a special package deal at the ad group level, you’ll want the callout to be more specific to what you’re advertising.You may want to highlight that your deal is the lowest price in the area or that it’s a comprehensive package. Google will display a maximum of 10 callouts with your ad.Call extensionsCall extensions are designed to make it easier for users to call your business directly from the ad. 
When using a call extension in your ad, users will see a button to click to call if they are on a mobile device. If they’re viewing your ad on a non-callable device, they’ll still see your phone number and can click through to your website. For example, if you run a clothing store and want people to call to schedule fittings or for any questions, you can include a phone number to encourage them to reach out by clicking the button in your ad.Message extensionsMessage extensions offer users the option to contact you directly from your ad, similar to call extensions.These are intended for mobile users who can communicate via text messages. 
If you’re using message extensions, your business must have a number capable of sending and receiving texts. You can set up these extensions so that you respond via phone number or email. If you respond with an email, it will show up as a text message to the customer.Price extensionsThe next extension I’ll discuss is the price extension. These are particularly useful for e-commerce or brick-and-mortar stores looking to highlight deals or costs associated with their products. 
You can also use price extensions to advertise the cost of services.You’re not limited to just selling products. When someone clicks on an item featured in your price extension, they are directed to the corresponding page on your site where they can make a purchase. For example, if you run a shoe store and are advertising a summer clearance, you can include individual prices of some summer sandals in your ad, in addition to advertising the sale.Location and affiliate location extensionsLocation extensions inform users of where they can find your store or location. 
An affiliate location extension lets people know who sells your product, which is beneficial when you create a product that is sold by vendors in multiple locations. 
For example, in this ad, you see an affiliate location extension indicating where you can purchase Ford vehicles.App extensionsApp extensions provide users who see an ad for your app with the option to download it from their respective app store. 
These appear on mobile devices where users can download your mobile app. Remember that app extensions are used in addition to your ad. The primary focus of your ad should be to direct people to your website.So if you only want to focus on app downloads, Google suggests using app promotion ads. To
