Pros and Cons of Managing Advertisement Blocking for Publishers
Publisher’s point of view on ad blocking
Advertisement blocking is a must-have for many publishers. For most of them, the reason behind using it, are legal issues. However, not for all.
All publishers working with the programmatic model know that one of the biggest differences from the “old” direct campaigns is limited control over the content and quality of ads. The vast number of advertisers that are able to buy and serve those ads makes management this matter very complicated.
Everything you always wanted to know about ad blocking but were afraid to ask
In this article, I will point out the best practices in the field of advertisement blocking in programmatic. Also, I will share limitations that publishers face with the technology used in programmatic ad management.
What can be blocked?
There are many approaches to the adblocking mechanism in different SSPs on the market.
Some give publishers quite wide and detailed options for managing their buyers’ pool from the account level (like Google AdX). Others, on the other hand, offer only the simplest solutions. There are, however, companies that do not give control away. They still require contacting customer support if you want to block an advertiser or content category from your site.
In almost all cases, there are two types of blockades:
Advertiser level:
This can be a specific domain to which the ads are being targeted, or a full account of the company that promotes many different bad-quality products/services.Category level:
Usually a wide branch of content, gathering all the advertisers and campaigns from a specific industry, such as Alcohol, Gambling, etc.
Most of the problematic categories and campaigns (like anything related to sex or violence) is blocked by the SSPs straight away. They simply do not comply with their policies. Others (like alcohol) require opting in from the publisher’s end.
If money is not the main issue, some publishers prefer to add more specific categories to the adblocking pool to feel safer from the legal and UX perspectives. Most of the small and medium sites go with blocking specific campaigns whenever they see something they don’t like.

Why should you block?
There are many answers to this question. From our experience, we can tell that there are three main reasons why publishers’ use the blocking.
Legal reasons:
In many countries, the law prohibits site owners from advertising specific products or services on the internet, or to specific groups of users. These categories include Gambling, Alcohol, Guns, and more. To avoid any problems with authorities, creating a legally-required list of blocks for each country is a must when a publisher starts with programmatic monetization. Of course, there are some sneaky advertisers that will try to find a way to avoid those blocks. Usually, the scale of such activity is small, and you can handle it case by case with additional blocks.User experience:
Even if the country legislation does not prohibit advertising for some products, usually site owners do not want their visitors to see certain creatives. They may contain disgusting photos of sick body parts related to dietary supplements. Sometimes they scam users by claiming they won an iPhone. Even if there is some revenue coming from those impressions, usually it’s worth much less than the churn of users created by this kind of content. Unfortunately, those kinds of ads are not easily blockable (not at the category level at least). Specific “domain” blocking or increasing the minimal floors usually helps. One good thing: spammy ads are almost never coming from the top SSPs that have bigger shares of the total publisher revenue.Business perspective:
The last reason behind advertisement blocking is the most subjective and requires a lot of analysis and long-term thinking. The effects of the decisions made for business reasons usually have more cons than in the previous two points. Publishers mostly have two business reasons for blocking. The first is competition-removing ads promoting competitors, which is very reasonable.
The second is the protection of their existing business, and here’s when the fun begins. Most publishers that sell direct campaigns to advertisers usually don’t want to lose those high eCPM budgets by selling cheaper in the programmatic channel. They decide to set high floors for those buyers or block them from buying programmatically at all, or at least on the Open Market level. They don’t take under consideration that very often direct and programmatic budgets are totally separate. Because of limited options for buyers in programmatic, publishers only lose some money. Especially now that the supply-path optimization phenomenon is getting much more popular among buyers. Without a very detailed pricing strategy and AB tests, it’s hard to make sure the game we decided to play is the most optimal from the monetization perspective.
Blocking limitations
With advertisement blocking, the technology publishers use comes with some limitations. Especially those that are still in development.
The most common limitation regarding programmatic blocking is the lack of advertiser recognition on the platform level. Even in the case of tools like AdX, you have large parts of revenue coming from the companies bundled as “Unclassified Advertisers” or “Google Adwords”. As a result, you cannot analyze what companies displayed ads on your site if you don’t see it with your own eyes on the screen (or get some notice from users). Also, even if you know the advertiser’s name, sometimes you cannot simply block it if the SSP does not recognize it among the list of advertisers.
Second big limitation
The second big limitation I already mentioned above is the inability to set any blocks on the account level. This means you have to write an email to the SSP account manager every single time you see something that you want to be blocked. You also have to take into account the wait time for their reply. It can take up to a couple of days depending on time zones.
The third and final roadblock is the fact that on tools like Open Bidding, the publisher cannot block anything on its own. To do so, the publisher must contact customer support. Even then, ad blocking is only available for the whole account, rather than specific domains. As long as it’s a 0:1 case of bad advertising, it is not a major issue.
If you happen to have 10 different websites, each in a different category, and you want to block competition from the same industry on only one of them, you simply will not be able to do it. The publisher then needs to make a business decision. Suffer the couple hundred ads per month featuring competition, or cut the revenue source provides. In some cases, the loss is up to a double-digit share of this revenue. The marketing team will say one thing, and sales will say the other.
A reasonable approach is key
As I think, most of the professionals working on programmatic inventory management will agree. Advertisement blocking is one of the most unpleasant and complicated parts of the job. It requires a lot of analysis, processing, and making strategic business decisions.
Our approach is usually quite clear:
- Set solid ground rules for the legally and policy-required blocks.
- Establish your business priorities regarding demand optimization.
- Know the pros and cons of each action and be aware of the results.
When you have the framework, what is left is much simpler daily management that does not require the involvement of many parties. What it requires is awareness that you will never be able to cut 100% of bad ads from the page. Of course, you should do your best to make it happen.
