Thanks to Mantis pre-scan and ongoing monitoring, Mantis was able to flag these issues and open up more inventory for smarter, more effective advertising. Their approach allows them to target more opportunities while ensuring ad placements are safe, suitable and seen by the right audience.
Almost half (47%) of Super Bowl content produced by Reach titles between 29 December and 28 January was blocked from receiving advertising by keyword blocklists.
According to data shared with The Media Leader by Mantis, Reach’s brand safety and contextual advertising solution, keywords such as “victims”, “injuries”, “wounds” and “incident” were commonly flagged by standardised agency blocklists. Such keywords often end up on blocklists due to their association with violence, even though they are commonly used in the context of innocuous stories, such as sports.
“It is this nuance that sweeping keyword blocklists can’t take into account and ultimately leave advertisers cut off from inventory that could be safe, suitable and relevant for reaching the right audiences,” said Mantis managing director Fiona Salmon.
Last year, studies from Stagwell and Teads/Lumen revealed that ads placed adjacent to stories covering politics or crime performed just as effectively compared with those next to more positive stories. The findings called into question whether keyword blocklists make sense at all. Yet publishers have struggled for years with articles being demonetised due to advertisers’ fears of having ads next to controversial or unseemly content, especially coverage of politics or war.
In July, The Media Leader reported that half of Reach’s Euros coverage was blocked from advertising due to similarly overzealous blocklisting practices. Publishers also saw a negative impact on Olympics coverage because numerous advertisers still have “Paris” on blocklists following terror attacks that took place in 2015. Later in autumn, two-fifths of articles about Halloween were demonetised for similar reasons.
“While agencies have made some progress in reducing the size of keyword blocklists — and agency-wide blocklists may be reviewed relatively regularly, sometimes quarterly — the brand-specific ones are often left untouched for long periods,” Salmon told The Media Leader.
“In many cases, both lists are applied at the same time, which can create inconsistencies in how content is classified as safe.”
The consequences of missing out on Super Bowl-related articles not only occur for publishers, but for brands seeking engaged audiences. According to the NFL, last year’s game between the Kansas City Chiefs and San Francisco 49ers was watched by a combined total of 3.4m unique viewers across Sky Sports and ITV in the UK, up 48% from the year before. The championship has become especially popular among valuable younger demographics, with the 2024 Super Bowl seeing a 91% year-on-year growth in under-35 viewers.
“We are seeing increased popularity around Super Bowl viewing and this will have an impact on the number of publications and articles covering the event,” Salmon noted.
“Given the Super Bowl’s late-night broadcast in the UK, many people may prefer to catch up on the event’s outcomes the following morning,” she continued. “This anticipated interest presents an opportunity for UK news outlets to prepare timely and engaging content to meet this demand.”
The 2025 Super Bowl kicks off on Sunday at 11:30pm GMT. The Kansas City Chiefs are returning for the fifth time in six years, facing off for the second time against the Philadelphia Eagles.
Mantis’ latest analysis consisted of 416 Super Bowl-related articles from Reach’s publisher network. Mantis used Google’s BigQuery service to compare standardised agency keyword blocklists with its own natural language understanding and contextual targeting solutions.
Salmon said articles were classified based on keyword detection and context: green for safe, red for unsafe with high confidence and amber for potentially unsafe but below the blocking threshold.
She added: “There is an opportunity for agencies to access more inventory that is safe and suitable for brand advertising during the Super Bowl and future sporting events.”
