ASA Rules Optival Betting Ad Shown on a Self-Exclusion Search Was Irresponsible

The Advertising Standards Authority has upheld a complaint against affiliate Optival after its paid search ad for betting bonuses appeared in response to a search for "self exclusion bookies". It is the second time in seven weeks the regulator has found an affiliate's negative keyword list was not enough to keep gambling ads away from people looking for help.

• The Advertising Standards Authority (ASA) upheld a complaint against affiliate Optival Ltd over a paid search ad for betting sites shown after a search for "self exclusion bookies"
• Optival said it had never targeted the phrase, ran negative keyword lists covering self-exclusion and GamStop, and blamed automated query matching
• The ASA found its controls were not sufficiently robust and ruled a breach of CAP Code rule 1.3 on social responsibility
• The ruling follows a September decision against Smart Gravity over a casino ad served on a "help with gambling" search, and another on an affiliate-made Midnite TikTok ad
• Gambling Commission rules make licensees responsible for their affiliates, and GamStop reported 614,738 consumers on its register in July

The ASA Finds an Affiliate's Search Ad Reached People Trying to Self-Exclude

The ASA published its ruling on Optival Ltd, which runs a betting comparison site, on 28 October, upholding the single complaint it received. According to the ruling, the paid-for search ad was seen on 10 August following a search for "self exclusion bookies". It promoted the "Top 15 Betting Sites UK" and invited readers to "Claim your Exclusive First Bet Bonus".

Optival told the ASA it had never targeted the phrase, supplying a Google Ads search term report showing no matching terms. It said it maintained negative keyword lists to block searches about self-exclusion, GamStop and problem gambling, and that the isolated incident fell below the platform's reporting thresholds and resulted from automated query matching. It said it would expand its exclusions across all current and future campaigns.

The ASA concluded that people making that search were likely to be seeking help to prevent their exposure to gambling, and were likely to include vulnerable people. It accepted that the site was an affiliate rather than a gambling service, but said the ad had the effect of promoting betting sites. Given the potential for considerable harm, it said gambling-related advertisers should have "extremely robust controls", and that such measures should already have been in place.

The ad breached CAP Code (Edition 12) rule 1.3 on social responsibility. The ASA told Optival the ad must not be served following that search again and that its search ads must be responsibly targeted. Companies House records Optival Ltd as incorporated on 21 May 2026. NEXT.io reported that the complainant had previously self-excluded; the published ruling does not say so, and does not name the brands the site promoted.

A Second Affiliate Search Ruling in Seven Weeks

On 9 September the ASA upheld a near-identical case against Smart Gravity Ltd, a casino review affiliate, whose casino ad appeared via Microsoft Advertising after a search for "help with gambling". Smart Gravity also supplied its negative keyword list and search term reports, but the ASA said its mix of broader keyword matching options risked ads appearing on searches that indicated gambling harm. That ad also breached rule 1.3.

The principle is older. In October 2019 the ASA ruled against Casumo, under the code's gambling rule 16.1, over a Google ad served after a search for "how to unsubscribe from all gambling", despite Casumo's argument that no list could anticipate every search variation.

The Licensing Rules Behind Affiliate Marketing

Under the Gambling Commission's social responsibility code 1.1.2, licensees in Great Britain are responsible for third parties they contract with, and those contracts must allow prompt termination, including where an affiliate breaches an advertising code. Code 5.1.6 requires licensees to comply with the CAP and BCAP codes.

Code 3.5.3 requires licensees to take all reasonable steps to stop marketing reaching self-excluded customers and to remove them from marketing databases within two days, and since 1 May 2025 code 5.1.12 has required remote operators to offer direct marketing opt-ins by product and channel. GamStop said in July that registrations rose 16% year on year in the first half of 2026, with a record 12,236 in May.

Negative Keyword Lists Are Now a Starting Point, Not a Defence

In both 2026 cases the affiliate produced its exclusion list and search term reports, and in both the ASA ruled against it. Automated matching is the advertiser's risk: if a campaign can surface an ad on a help-seeking query, the controls were not robust enough. Optival's ruling asks for "extremely robust" controls, where September's asked for "very robust" ones. Affiliates now have two rulings saying the platform's algorithm will not be accepted as the cause.

The Commission's Marketing Rules Stop at the Database

Codes 3.5.3 and 5.1.12 govern marketing to known customers, whose details can be checked against a register. A paid search ad answers an anonymous query, and code 3.5.3 excludes blanket marketing aimed at a geographical area. That leaves the ASA's targeting rules as the main protection at the moment someone searches for a way out. With 614,738 people registered with GamStop, the pool of potential searchers is large.

Operators Carry Their Affiliates' Keyword Risk

The ASA directed its action at Optival alone. Under code 1.1.2, though, any licensee contracting with an affiliate must be able to end the relationship over an advertising code breach. A parliamentary push to overhaul gambling advertising is already testing the self-regulatory model, and repeated affiliate breaches give its critics more evidence.

The ASA's message to affiliates is that good intentions and an exclusion list do not discharge the duty. Whether licensed operators enforce it through their affiliate contracts will decide whether the next ruling looks the same.
