What is it that makes your business standout from the competition? Award-winning? Open 24 hours? Only local ingredients? Free Shipping on All Orders? Whatever it is, Google is giving you a chance to tell the world with the new AdWords Callout Extensions.
Callouts create an additional line of descriptive text underneath your existing ad. A callout must be less than 25 characters but you can create up to four per ad. You can’t use “gimmicky” symbols such as hearts and smiles (Do advertisers really use hearts and smiles on their ads?) and you can’t duplicate callouts – meaning you can’t just write “free shipping” four times.
For general campaigns, Google recommends words such as “special discounts” or “price-matcing.”
