Google has upgraded its Ads Diagnostic Tool. This tool is used by AdWords advertisers to determine why their ads are not appearing on a Google results page. Earlier, it used to list just one reason, but now it has been improved and it lists multiple reasons and multiple issues that should be fixed.
The tool can be accessed within an AdWords account, with the help of the a magnifying glass icon next to an individual keyword in an ad group or from the account's 'Tools' page.
The Inside AdWords crew says, "What might these multiple reasons be? Consider a situation where your campaign has met its daily budget, causing your ad to stop showing for the day. Additionally, the specific keyword might be inactive for search. You'll now be able to learn about these multiple issues immediately so you can adjust your budget settings and modify the keyword based on the Ads Diagnostic Tool results."
This will be really helpful for AdWords advertisers.
