When potential consumers come across your ad on Google, it may be the first time they’re encountering your brand. With limited characters and space in the heading and description for text ads, using extensions is another opportunity to expand on exactly what your business sells or wants to highlight. And the best part? These are FREE to add!

TYPES OF GOOGLE AD EXTENSIONS
Sitelink Extensions

Dependent upon the type of campaign and device it's being viewed on, you'll need anywhere from 1- 8 sitelinks. There may also be descriptions that show underneath the sitelink, another opportunity for you to add additional relevant information about your brand or business.
TIP: Don't confuse your consumers! Keep sitelinks relevant to the original ad. Use descriptions to build off your ad versus repeating the same information.
Promotion Extensions
Highlight sales and specials without making constant updates to your Search ad when you use promotion extensions.
