What the results mean
- Responsive search ad
- The standard Google search ad. You give up to 15 headlines and 4 descriptions and Google tries different combinations.
- Display path
- The short words shown after your domain in the ad, like yourshop.in/ac-repair/pune. They do not need to be real pages.
- Call asset
- Google's approved way to show your phone number with a tap-to-call button, instead of putting the number in the text.
Common questions
How many characters can a Google Ads headline have?
30 characters per headline and 90 per description. Wide characters, such as Chinese, Japanese or Korean, count as two. Hindi characters count as one each.
Why was my ad disapproved for capitalisation?
Google does not allow whole words in capitals used for emphasis, like FREE or BEST. Short acronyms such as GST or AC are fine. Write words in normal or title case instead.
Can I put my phone number in the ad?
Not in the headlines or descriptions. Add a call asset in Google Ads instead; it shows your number with a call button and is counted as a call.
