ASA rules betting affiliate ad shown for self-exclusion search was irresponsible

The Advertising Standards Authority (ASA) has upheld a complaint against betting affiliate Optival Ltd. This is after a promotional advert appeared in response to a search for gambling self-exclusion information.

The ruling was published on 28 October. It concerned a paid search advertisement for bestbookiesandbettingsites.co.uk, seen on 10 August 2026.

A consumer searching for “self exclusion bookies” was shown an advert promoting a comparison of betting sites alongside first-bet bonuses and welcome offers.

Search indicated potential vulnerability

The  ASA considered that someone using the search phrase was likely to be looking for advice or support to prevent exposure to gambling services.

Serving promotional betting content in that context risked reaching vulnerable people attempting to manage or reduce their gambling.

Although Optival operates an affiliate comparison website rather than accepting bets itself, the regulator said the advertisement still promoted bookmakers and online betting services.

It therefore expected the business to take particular care over who could see its advertising.

Optival points to automated matching

Optival said it had never deliberately targeted the search phrase. The company reviewed its Google Ads search term reports after receiving the complaint and supplied a screenshot showing no matching searches across its campaigns.

It also said dedicated negative keyword lists were already in place to block searches involving self-exclusion,  GamStop and problem gambling. Negative keywords allow advertisers to prevent adverts appearing against specified search terms.

Optival suggested the appearance resulted from the platform’s automated query matching. It described it as an isolated incident falling below reporting thresholds.

The company committed to expanding its exclusions across current and future campaigns.

Existing safeguards judged insufficient

The ASA welcomed that commitment but concluded that adequate protection should already have been in place when the advertisement appeared. Its assessment focused on the advert reaching a potentially vulnerable consumer. This is despite the advertiser’s explanation that the search phrase had not been intentionally selected.

The regulator found the targeting breached CAP Code rule 1.3 on social responsibility. It instructed Optival not to serve the advert following the same search again and to ensure its search advertising was responsibly targeted. The published action did not announce a financial penalty.

"Because we considered there was a strong likelihood that vulnerable consumers seeking to self-exclude from or reduce their exposure to gambling services and ads had been served an ad promoting betting sites following the search “self exclusion bookies”, we concluded the ad had not been responsibly targeted." - ASA

The ruling shows how important it is for gambling affiliates to check how search campaigns operate in practice. This includes whether automated matching can expose people seeking self-exclusion support to betting promotions.
