Power advertising technology AI from audience targeting to brand safety

"Zilliz Cloud is a fully managed vector database built for semantic audience matching, contextual targeting, and fraud detection in ad platforms. It delivers sub-10ms latency at billion-user scale — trusted by SmartNews (100M+ daily vector updates) and Tokopedia. SOC 2 Type II certified."

AI Capabilities for the Next Generation of Advertising Technology

"Every adtech challenge — audience targeting, contextual matching, fraud detection — is a similarity problem. Zilliz Cloud solves them at bid-time latency and billion-user scale."

Cookieless Targeting

Build Lookalike Audiences Without Third-Party Cookies

Encode first-party behavioral signals into user embeddings and find similar users via nearest-neighbor search â no cross-site tracking required. Move from declining cookie match rates to 100% first-party addressability with continuous similarity scores instead of binary segment membership.

Semantic Contextual Targeting

Target by Page Meaning, Not Just Keywords

Embed page content semantically and match ad campaigns to context by meaning â distinguishing 'shooting a film' from violence, 'Apple product launch' from fruit recipes. Recapture the 76% of premium inventory that keyword blocklists incorrectly block, while improving relevance for advertisers.

Creative-to-Context Matching

Match Ad Creatives to Page Content at Impression Scale

Embed both creative assets and page content into a shared vector space using multimodal models. Find the highest-affinity creative-context pairs in real time at bid time â replacing manual tagging and pre-computed rules with automated semantic matching across millions of impressions per second.

Fraud & Bot Detection

Detect Sophisticated Ad Fraud Before It Drains Budget

Embed behavioral sessions as vectors where legitimate human patterns cluster together and bot behavior appears as outliers. Catch AI-powered bots that mimic human scrolling and click timing â the kind that rule-based thresholds miss entirely, even as they generate healthy-looking CTR and conversion metrics.

Brand Safety

Semantic Brand Safety Beyond Keyword Blocklists

Classify page content by meaning, not individual words. Measure semantic distance from brand-unsafe concepts rather than scanning for flagged keywords â so photo shoots, basketball highlights, and film production content stop getting blocked while genuinely unsafe inventory is correctly identified.

Creative Intelligence

Detect Creative Fatigue and Cannibalization Across Campaigns

Embed all active creatives and search for near-duplicates across your library. Identify creative clusters that are too visually or textually similar before they cannibalize each other's performance â shifting from reactive CTR monitoring to proactive creative rotation.

Why Zilliz?

Why ad platforms choose Zilliz Cloud

"Ad platforms need sub-10ms latency for RTB windows, scale for billions of user profiles, and real-time updates as behavior changes. Zilliz Cloud meets all three — proven in production at SmartNews (<10ms P99, 100M+ daily updates) and Tokopedia."

100K+QPS

Handle bid-time queries at programmatic auction throughput

RTB auctions process millions of bid requests per second with an 80-120ms total window. Zilliz Cloud handles 100K+ queries per second so that semantic audience scoring, contextual matching, and fraud checks fit within the latency budget â alongside your existing bidding infrastructure, not instead of it.

<10msLatency

Return similarity results within the RTB auction window

DSPs have 10-50ms for internal processing before the auction closes. Zilliz Cloud delivers sub-10ms P99 vector search â proven in SmartNews's production ad system. Fast enough for inline audience scoring, contextual matching, and fraud detection without adding latency to the bid path.

10B+vectors

Index billions of user profiles, pages, and creative assets

Large ad platforms maintain hundreds of millions to billions of user profiles, serve ads across millions of publisher pages, and manage thousands of creative variants. Zilliz Cloud supports tens of billions of vectors in a single index â your entire user base, inventory catalog, and creative library searchable together.

-10xCost

Replace proprietary targeting tools with infrastructure you own

Proprietary contextual targeting services, brand safety vendors, and walled-garden lookalike tools charge CPM-based fees that scale with your spend. Zilliz Cloud provides the semantic matching infrastructure at a fraction of the cost â and you control the models, the data, and the methodology.

Hybrid search with metadata filtering

Hybrid search with metadata filtering

Combine semantic vector similarity with structured filters â match audiences filtered by geography and recency, score pages filtered by language and publisher tier, or retrieve creatives filtered by format and campaign. One query, both signals.

Real-time index updates

Real-time index updates

User behavior changes throughout the day. Zilliz Cloud supports 100M+ daily vector updates without performance degradation â keeping audience embeddings, contextual scores, and fraud models current, not stale.

Multimodal similarity search

Multimodal similarity search

Match ad creatives (images + text) to page content (articles + images) in a shared embedding space. CLIP-style cross-modal search enables creative-to-context matching that text-only systems cannot achieve.

Automatic and elastic scaling

Automatic and elastic scaling

Ad traffic spikes are unpredictable â prime-time surges, tentpole events, seasonal peaks. Scale compute up for high-traffic periods and back down automatically, paying only for what you use.

Multi-tenant architecture

Multi-tenant architecture

Serve multiple advertisers, campaigns, and DSP clients from a single deployment. Fine-grained isolation ensures one advertiser's data and models never leak to another.

Enterprise-grade compliance and reliability

Enterprise-grade compliance and reliability

SOC 2 Type II certified, GDPR compliant, 99.95% SLA. BYOC deployment available for ad platforms with strict data residency and privacy requirements under GDPR, CCPA, and TCF 2.0.
