HuffPost UK this week announced the adoption of DeeperDive, agenerative AI answer engine developed by Taboola (Nasdaq: TBLA) that lives directly on publisher websites and draws exclusively from each publication's own editorial archive. The announcement, made on 14 April 2026 in London, places HuffPost UK among a growing list of major news organisations that have deployed the technology as search referral traffic continues to erode.

The partnership is focused on increasing readership and engagement while opening what Taboola describes as additional revenue streams. For the marketing industry, the deal illustrates how publishers are attempting to reclaim the audience relationship that AI-powered search platforms have progressively weakened over the past two years.

What DeeperDive does

DeeperDive is embedded directly within a publisher's website rather than functioning as a standalone destination. Readers can type questions into a conversational interface, and the system returns answers sourced exclusively from that publication's own content. The interface also surfaces suggested follow-up questions and links to related articles from the same site.

According to Taboola, the system draws from years of proprietary, real-time content created by journalists and editors across the open web. Unlike conventional AI search engines, which aggregate information from thousands of sources and synthesise a single response, DeeperDive confines every interaction to the host publisher's archive. Each answer includes direct links to relevant articles on the same site, designed to pull readers deeper into the publication rather than toward an external platform.

The technology also taps into behavioural data from Taboola's broader network. According to the company, this network reaches approximately 600 million daily active users across 9,000 publisher partners globally. That data informs which questions to prompt, which topics are trending at any given moment, and which answers are likely to satisfy a reader who has already shown interest in a particular subject. Taboola describes this as a "pulse of the internet" capability - a real-time signal that helps the system surface contextual, timely responses rather than relying on static training data.

The user interface visible in a screenshot provided with the announcement shows the DeeperDive bar at the top of the HuffPost UK homepage. A sample prompt - "What is the total UK defence spending increase since the Cold War?" - appears alongside two additional suggested questions about the Strategic Defence Review and global tensions involving Iran and Ukraine. The design integrates directly into the publication's existing look and feel.

What the executives said

According to the press release, Cate Sevilla, Editor-in-Chief at HuffPost UK, said the tool allows the publication to use AI in a way "that is helpful to our audience, without compromising on quality, so that we can continue to provide UK audiences with the accurate and compelling journalism for which HuffPost is known."

Adam Singolda, CEO and Founder at Taboola, said that "HuffPost readers can enjoy a more personalised experience than ever before, as they ask their own questions and learn about the topics that matter to them most."

The monetisation angle

DeeperDive is not purely an editorial product. According to Taboola, the system has the potential to create a new monetisation channel for publishers by inserting contextually relevant, high-intent advertisements directly into the AI-powered results page. Publishers would, in effect, capture search-like advertising revenue within their own digital environments - turning reader inquiries into commercial opportunities while keeping users on the site.

Taboola positions this as an alternative to the ad revenue that search platforms have traditionally captured. The argument is that when a reader asks a question on HuffPost UK about financial planning, travel destinations, or a favourite sports team, that intent signal has commercial value. Historically that value has accrued to search engines. Under the DeeperDive model, it accrues to the publisher instead, since the query is made on publisher-owned inventory.

The company also highlights a data benefit for editorial teams. The DeeperDive dashboard gives editors visibility into the specific questions their readers are asking - a signal that has historically been accessible only through external SEO keyword tools. According to Taboola, this data can guide editorial decisions and homepage choices toward topics with demonstrable audience interest.

Context: a publisher industry under pressure

The timing of HuffPost UK's adoption reflects a structural challenge that has reshaped digital publishing since 2024. Google Web Search traffic to news publishers declined from 51% in 2023 to 27% in the fourth quarter of 2025, according to NewzDash data analysed across more than 400 publishers globally. Google Discover climbed to 67.51% of Google traffic to news organisations during the same period.

The role of AI Overviews in that decline has been documented repeatedly. Ahrefs research published in February 2026found that AI Overviews now correlate with a 58% reduction in click-through rates for top-ranking pages - nearly double the 34.5% figure the same company recorded in April 2025. A separate study by Seer Interactive published in November 2025 found organic click-through rates for queries featuring AI Overviews fell 61%, while paid CTRs on those same queries dropped 68%, between June 2024 and September 2025.

The IAB Europe published a framework in September 2025 proposing three mechanisms for AI publisher compensation - content access controls, discovery protocols, and monetisation APIs - in response to what the document described as a "paradigm of publisher remuneration for content ingestion." According to Similarweb data cited in that report, referrals from AI platforms increased 357% year-over-year in June 2025, and news and media publishers saw those AI referrals increase 770% over the same period, suggesting that while AI platforms sent more raw traffic, the overall displacement from search was severe.

For UK publishers specifically, the problem is acute. Reach, the UK and Ireland's largest commercial news publisher, deployed DeeperDive across Express and Daily Star in early 2026 in a move that placed the company among the first major UK groups to deploy on-site AI answer technology. National World, another large UK regional publisher, signed a multi-year deal with Taboola in October 2024 covering AI recommendations across more than 60 news titles reaching 15 million monthly readers - a deal that preceded DeeperDive but reflected the same broader trend of UK publishers seeking closer technology partnerships to offset search losses.

DeeperDive's trajectory since launch

Taboola first announced DeeperDive on 11 June 2025, with Gannett | USA TODAY Network and The Independent as launch partners. Gannett, which operates approximately 220 local markets across 43 US states and reaches roughly 140 million monthly unique visitors digitally, implemented the technology first in North America.

The Bangkok Post adopted the system on 18 November 2025, becoming the first media organisation in Southeast Asia to deploy DeeperDive. The newspaper has published continuously since 1946.

By April 2026, the product had reached nearly 7 million monthly active users - a figure Taboola has itself contextualised against the dominant generative AI platforms. According to the company's own comparative data, ChatGPT leads with an estimated 810 million monthly active users, followed by Gemini at 750 million, Grok at 60 million, Perplexity at 30 million, and Claude at 20 million. Taboola's embedded engagement model is structurally different from those standalone platforms, but the raw gap in scale is significant.

Also in April 2026, Taboola announced global expansion into six new languages - French, German, Hebrew, Japanese, Korean, and Spanish - bringing publishers in France, Israel, Japan, South Korea, and Spanish-speaking markets onto the platform. According to data from that announcement, approximately 50% of user questions on DeeperDive concern the last 24 hours of news, entertainment, and sports. The top question categories are politics, sports, finance, entertainment, and shopping.

Publishers that have integrated DeeperDive are seeing engagement rates of up to 17%, according to Taboola, meaning roughly one in six readers continues interacting after an initial article. Historically, recirculation rates on publisher sites - the likelihood that a reader who arrives on one article clicks through to a second - have remained in the low single digits for roughly 30 years.

Why this matters for the marketing community

The HuffPost UK deal sits at the intersection of two problems that have dominated ad tech discussions since 2024: the collapse of search referral traffic and the search for new monetisable attention on publisher properties.

For advertisers and media buyers, the emergence of publisher-embedded AI answer engines raises a specific question about inventory. If readers ask high-intent questions - about financial products, travel plans, consumer electronics - inside a publisher environment rather than in a search box, then the contextual advertising attached to those answers becomes a new category of premium inventory. That inventory would carry editorial trust signals that search inventory typically lacks. It would also sit outside the walled gardens of Google and Meta.

Whether that inventory will scale to a level that materially affects campaign planning is not yet answerable from the current data. Seven million monthly active users across Taboola's entire DeeperDive network is a modest figure relative to the platforms advertisers routinely plan against. HuffPost UK is one node in that network, not the whole of it.

What the deal does confirm is that the on-site AI answer engine model is gaining adoption among credible editorial brands - not just regional outlets or vertical publishers. HuffPost UK has a distinct identity and audience in the UK market. Its adoption of DeeperDive signals that the technology has moved past early-adopter territory into mainstream editorial consideration.
