Google recently announced a new extension for paid ads.  Callout extensions (see example below) allow you to include yet another line of text in your ad, expanding page real estate and providing key information about your brand or service.

Google Callout Extensions Example

They look like sitelinks, but are not clickable.  Their purpose is more to encourage focus on the main message of the ad, providing additional promotional information or highlighting features of your product.   As with sitelinks, their presence is proven to lead to a higher clickthrough rate. Below is a helpful grid comparing sitelinks vs. callouts.

Callout Extensions vs. Sitelink Extensions

Callouts are shown at Google’s discretion but they do provide several tips to ensuring the chances they show are high.

  • Keep text short: Using a maximum of 12-15 characters is ideal. This increases the amount of callouts that can show and gives AdWords more callouts from which to choose. Think of a callout as a bullet point, rather than a complete sentence. “Free shipping” instead of “We have free shipping.”
  • Be specific: Where appropriate, try to use specific details to help a potential customer decide whether your site contains the information they’re looking for: “4.7in LED display” vs. “Large LED display”, “34 MPG max mileage” vs. “Great fuel economy”
  • Capitalize words sparingly: We’ve learned that ads see better performance with callouts that use sentence case rather than title case, i.e. “100% silk” vs. “100% Silk”.

As with other ad extensions, there is no additional cost to show callouts.  You’ll be charged as usual for clicks on your ad.
