The Hidden Cost of Keyword Blocking
Brand safety is designed to help advertisers avoid unsuitable environments. But when brand safety controls become too broad, they can start limiting the reach advertisers are trying to achieve.
Negative keyword lists are commonly used to prevent advertising from appearing alongside content a brand considers unsuitable. While they originally emerged as a way to avoid low-quality or MFA ad environments, their use has become increasingly broad. The challenge is that a keyword alone does not always tell you what an article is actually about.
Consider the word “rally.”
In one article, it might describe a political event. In another, it might refer to markets rallying after a positive earnings report. If an advertiser blocks the term to avoid political coverage, they could also exclude relevant financial articles – and the investors, business leaders, and other valuable audiences reading them.
The keyword is the same. The context is not.
When Keyword Blocking Goes Too Far
And “rally” is far from an isolated example.
Integral Ad Science recently partnered with Reuters to examine news content that had been classified as suitable through contextual analysis. They found that 54% of suitable Reuters news URLs would still have triggered a typical keyword blocklist.
That highlights a wider challenge with keyword-only controls. Terms such as “fire,” “shot,” or “drug” may appear in sensitive stories, but they also appear regularly within suitable stories covering areas such as entertainment, healthcare, technology, and business.
When those words are blocked without considering the wider article,advertisers can lose access not only to relevant content, but to the audiences reading it.
This is especially relevant across premium financial, business, and news environments, where topics naturally overlap. Political developments can influence financial markets. Cybersecurity is an important part of technology and business reporting. Healthcare stories often contain language that may appear sensitive on its own while being completely appropriate within the full article.
The result is that a control designed to protect a brand can sometimes filter out content that was never actually unsuitable in the first place.
Looking Beyond the Keyword
Brand safety and suitability will always be an important consideration for advertisers. There will always be topics and environments that advertisers are right to avoid.
The challenge is to apply those controls with greater precision.
Contextual targeting looks at the wider meaning of an article rather than relying solely on individual terms. This can help distinguish between content that is genuinely unsuitable and content that simply contains a word associated with a blocked topic.
It also reflects how people actually consume content. Readers understand the difference between a political rally and a market rally because they understand the context around the word. They don’t evaluate an article based on a single term in isolation.
For advertisers, that distinction can mean maintaining appropriate brand suitability controls without unnecessarily limiting access to relevant audiences.
The answer isn’t to remove controls altogether. It’s to make them more precise.
Finding the Right Balance
Effective targeting is not only about identifying the right audience. It is also about making sure the controls around a campaign are not filtering that audience out.
At Dianomi, we use contextual targeting to connect advertisers with relevant audiences across premium financial, business, technology, and news publishers. We believe brand suitability starts with choosing trusted publishers and having full transparency into where your ads appear.
By aligning advertising with the content audiences are actively engaging with, brands can reach relevant readers in trusted environments while maintaining their brand suitability requirements.
Negative keyword lists remain a valuable tool, but applying them too broadly can mean excluding opportunities that were never unsuitable in the first place.
Brand safety remains essential, but understanding context can help ensure those controls work alongside, rather than against, audience targeting. The goal isn’t to choose between brand suitability and reach. It’s to find the right balance between the two.
Want to find that balance for your next campaign? Get in touch with Dianomi to learn more about how contextual targeting can help you reach relevant audiences without filtering out valuable opportunities.
