What are the effects of ad blocking software?

Ad blocking software is designed to block ads served by many ad servers, including AdSpeed Ad Server. Therefore, we will not be able to serve ads and record impressions/clicks to visitors who enable ad blocker on their computers. Impressions and clicks reported in your account do not include these visitors since no ads were served to these visitors.

Reporting Discrepancies

Ad blocking is one of the most common reasons for ad metric discrepancies. For example, analytics software (like Google Analytics) might report a higher view count because they are often not blocked by the ad blocker while all popular ad servers are on the ad blocker's list.

Percentage of Visitors with Ad Blocking Software

The ad blocking rate is not the same across websites. It depends on a number of factors, including demographics, traffic sources and your site itself. In order to detect and measure the number of visitors with ad blocker, there are several ways:
  • Use the code to detect ad blocker and record into your web analytics, like Google Analytics, or
  • Setup a comparison test between a native pixel/image that does not get blocked and a pixel ad served by AdSpeed that is likely to be blocked by the ad blocker. Put both pixels (one do not get blocked and one served by AdSpeed) on your homepage and compare the gross impressions/hits between them to figure out the percentage of visitors with ad blocker. For the native pixel, you can use your web analytics software to count the number of hits. For the ad in AdSpeed, you can see its impression report.

Bypassing Ad Blockers

Although there are some technical tricks to bypass ad blockers, it is not a sustainable solution as ad blockers frequently update their algorithms and block lists. Therefore, we choose not to implement these technical tricks to bypass the ad blockers.

More important, if the visitors' preference and decision is not honored and they keep seeing annoying ads then that would not be a suitable long term solution. Doing so only annoys your visitors more and they will have an overall negative feeling about your website and your advertisers.

It is better to compromise and come to an agreement. If ad blocking significantly affects your revenue, you should find a more cooperative and sustainable approach that works for both your visitors and your advertisers. Depending on your preference and situation, you can serve only non-intrusive and acceptable ads, let your visitors know that your business depends on advertising revenue, and/or ask your loyal visitors to disable the ad blocker specifically for your site or donate a small amount if they choose not to view ads.

Ad Blocking Methods

There are different methods utilized by ad blockers: some resolve the ad server's known IP addresses or hostnames to a local/private IP (, others remove/strip the IMG tag before displaying the page to end-users (Norton Personal Security/Firewall). If you use a private brand, some hostname-based ad blockers might not recognize your own ad serving sub-domain as a known ad server and therefore allow ads to be served.

Partial Ad Blocking

Also there are certain browser's add-ons and plugins that act as a partial ad blocker. The original ads are replaced with other contents (images, widgets, apps, or their own ads). Some of these plugins include: OverApps, Add-Art, PWS Toolbar. This approach can cause confusion for the website owner and their advertisers who see something else instead of the expected advertisement.
