With Google AdWords each advertiser looks at success differently based on your business goals. There are a few things to look for when it comes to figuring out whether your ads and keywords are performing well.
Look at your Ads tab to see if they are running. In the status column, you’ll see the information on the current status of each ad. If you click the icon of a speech bubble, you’ll be able to see the summary of your ad’s status.
To get a faster idea of how well your ads are doing, check the clickthrough rate (CTR) on your ads tab. This will show how often users are clicking your ads. Just note, a CTR under 1% on Google and the Search Networks shows that your ads are not targeted to a relevant audience. If your number is below this, try improving your ads as soon as possible.
The ad performance report will let you view performance data for your ads; this includes average position, clicks and impressions, CTR and cost.
If you have more than one ad in your ad group, your ads will be rotated and taking turns showing. When you compare these ads, you can see which ones your customers think is the most compelling.
