In any Adwords campaign, Google has to approve your ad before it can be presented online. This means that your ad has to meet the criteria laid out in terms and conditions and in the other documents Google provides that state their editorial and ad content policies. The destination website also has to meet the criteria in terms and conditions or the ad will be rejected.

When you access the ad diagnostics tool, it looks at data that is specific to each query and all the related ads based on the account data at that particular time. However, it is important to realize that no data provided in the reporting tools of Google is truly real-time. There is about a three hour or more delay, so very recent changes will not be reflected in the reporting.

There are many things within your Adwords account that can impact the display of your ad. The diagnostics tools will take these into account. Included are advertisement and keyword approval status, the cost per click and your advertising budget settings, the keyword performance, audience targeting settings and ranking status.

One reason the diagnostic tools might return is that your advertising budget is too low to allow your ad to be delivered frequently. This can, of course, be easily changed by increasing your advertising budget settings and paying more per click. Since ads are delivered with those paying the most per click being given priority, the more you are willing to pay for each click, the more often your ad will be delivered to an audience.

There is also a wizard for debugging why an ad can't be seen. This allows you to learn if something is wrong with the ad you submitted which prevents its being delivered or seen by an audience.

By using the Adwords diagnostic tool, you can refine your Adwords campaign, getting the most for your advertising budget. It is not necessary to go blindly through an Adwords campaign. Google provides all the tools needed to make your ad campaign the most successful. You simply have to access and use those tools to optimize your campaign.
