Every ad network assigns categories to the campaigns it serves. Those labels provide a useful starting point, but they don’t always tell publishers enough about what is actually being advertised. A campaign categorized as “Gaming” may promote a gambling app, while an ad labeled “Social Networking” may lead users to a dating service. For publishers with specific audience standards, content policies, or regulatory requirements, relying on network categories alone isn’t always enough.
This is where AppHarbr comes in. Instead of relying solely on network-assigned categories, it analyzes the ad creative, landing page, and destination app to determine what the ad actually contains and where it takes users. That analysis is the foundation for filtering policies built around content categories, app store classifications, custom rules, and advertiser-level controls.
How AppHarbr Classifies Ad Content
To determine what an ad is promoting, AppHarbr analyzes the ad itself rather than relying solely on the category assigned by the ad network. Before an ad is served, AppHarbr evaluates multiple elements of the ad experience, including evaluating the creative’s content- text & visual, the landing page, and, when the destination is an app, the category assigned to that app in the App Store or Google Play.
The results of this analysis are used to classify ads across multiple dimensions. Content classifications identify what is being promoted, while App Store and Google Play classifications identify the category of the app being advertised.
Building a Baseline Policy with Content and App Categories
Once ads have been classified, publishers can use those classifications to define a baseline filtering policy for their inventory.
Content categories focus on what an ad actually contains, whether or not it was labeled correctly upstream. An ad classified as “Gaming” by its demand source may still be flagged for weapon imagery, and a gambling ad doesn’t escape a filter simply because it was labeled differently. Because AppHarbr evaluates the creative and landing page directly rather than the category label assigned upstream, publishers can set policies around categories such as Alcohol, Cryptocurrency, Gambling, or Sexually Explicit material based on what the ad actually contains.
App store categories add a separate layer of control. Rather than focusing on the content of an ad, they allow publishers to make decisions based on the type of app being advertised. A publisher may choose to block specific verticals, prevent competitors from advertising within the same category, or apply different policies to finance, social networking, or gaming apps.
Together, these two classification systems provide a broad foundation for ad quality policies. From there, publishers can introduce more granular controls to handle competitors, partnerships, approved advertisers, and other account-specific requirements.
Creating Custom Rules with Blocklists, Allowlists, and Keywords
Baseline policies cover broad categories, but publishers often need more precise rules for specific advertisers, destinations, or campaigns. That is where custom controls come in.
AppHarbr allows publishers to create account-specific blocklists and allowlists using app IDs and domains. A blocklist applies when a broader category is allowed but a specific app or domain should not run: blocking direct competitors or flagged destinations without affecting the rest of the category.
Allowlists work in the opposite direction. When a category is broadly restricted, publishers can still approve specific exceptions. A sports app that blocks gambling by default but has an exclusive sports betting partnership can allowlist that partner’s domain directly, keeping the category rule intact without disrupting the deal.
Keyword and keyphrase filtering adds a third layer. Publishers can define specific words or phrases that AppHarbr scans for across the creative and landing page. It’s useful for targeting a particular campaign slogan or a specific promotional claim without blocking the advertiser or category as a whole.
Together, these controls let publishers move from broad category policies to precise, account-specific rules that accommodate partnerships, competitors, and unique content requirements.
Reviewing Advertisers and Creatives in AdWatch
Categories, blocklists, allowlists, and keywords can handle most ad quality decisions automatically. But there are cases where the right call requires reviewing the ads themselves. An advertiser may be generally acceptable while running a single problematic campaign, or a new brand may appear that warrants review before any policy changes are made.
AdWatch provides visibility into the advertisers and creatives appearing across a publisher’s inventory. When the ads are organized by brand, it’s easy to identify recurring advertisers, understand the campaigns they are running, and decide whether they align with the app’s policies and audience.
From there, publishers can act at whichever level makes sense. Blocking at the brand level removes all future ads from that advertiser. Blocking at the creative level targets only a specific execution, including similar variations across demand sources, leaving the rest of that brand’s campaigns eligible to run.
The result is a more precise approach than category blocking alone, one that lets publishers address specific problems without restricting demand more broadly than necessary.
Taking a Layered Approach to Ad Quality
No single control can account for every ad quality decision a publisher needs to make. Category-level policies help define the broad boundaries. Custom blocklists, allowlists, and keywords handle the exceptions. AdWatch gives publishers the visibility to review advertisers and creatives when a more specific decision is needed.
Together, these layers give publishers a more flexible way to manage unwanted content without relying on blunt exclusions alone. Instead of blocking entire categories or advertisers by default, teams can apply the right level of control for each situation, protecting the user experience while keeping valuable demand eligible to run.
For app developers, that means ad quality management can become more precise, more consistent, and better aligned with the standards of each app.
