This is a friendly reminder that starting on January 31, you’ll only be able to create and edit text ads using the expanded text ads format. You’ll no longer be able to create standard text ads. While this will be the last date to create them, existing standard text ads will continue to serve.
Expanded text ads can deliver great results, particularly with a commitment to testing new creatives.
While making similar improvements to your ads, keep some best practices in mind:
Implement multiple versions of your ads. Aim for at least 3-5 per ad group.
Leave your standard text ads running. You can’t create new ones, but the old ones can still serve. Don’t delete them until they stop receiving impressions on their own or the message is no longer accurate.
Plan to optimize your ad rotation for clicks or conversions. These options give preference to ads that are likely to perform better.
It has been six months since Google roll out the expanded text ads. So, a majority of its users are comfortable with the new format already.
