HOW TO: Write successful ad text
Writing ads is an art. The best way to see which ads bring the best results is to write three or four at one time. Then, let them gather at least 1000 impressions. Ads with the highest CTR are top performers. Below are some tips to help create compelling ad text.
Text should be clear and well-written
It should highlight the differentiating characteristics of an advertiser's product or service.
Include keywords in the ad title
Since the keyword entered is what people are looking for, ads with keywords in the title stand out. Also, keywords that a user enters into Google.com appear in bold in the ad.
