FAQ
Quantcast is an audience intelligence and programmatic advertising platform. It operates two primary products: Quantcast Measure, a free audience analytics tool for publishers that collects real-time visitor demographic and interest data via a JavaScript tag installed on the publisher's site; and Quantcast Advertise, an AI-powered demand-side platform (DSP) that uses Quantcast's audience intelligence to buy programmatic display and video advertising across the open web. Quantcast is primarily used by digital advertisers and media planners who need audience targeting data for programmatic campaigns, and by publishers who want real-time audience analytics for monetisation and media kit reporting.
Quantcast does not measure SEO performance, Core Web Vitals, or any of Google's organic ranking signals. Quantcast Measure collects audience data — who your visitors are (demographics, interests, behaviours) — not how well your pages perform for organic search. It does not report CrUX p75 LCP, INP, or CLS, does not audit structured data or canonical tags, and does not diagnose technical SEO issues. For Core Web Vitals specifically, DeepSEOAnalysis reports CrUX p75 field data — the exact data from the Chrome User Experience Report that Google uses as a Page Experience ranking signal — which Quantcast does not provide.
Programmatic advertising — which is Quantcast's primary focus — is the automated buying of paid ad inventory (display banners, video pre-rolls, native placements) across publisher websites using real-time bidding (RTB). Traffic from programmatic ads is paid for on a per-impression or per-click basis and stops when spend stops. Organic SEO — which DeepSEOAnalysis supports — is the practice of improving a page's ranking in unpaid search engine results by optimising for Google's ranking signals: Core Web Vitals (CrUX p75 LCP, INP, CLS), structured data validity, technical crawlability, and content relevance. Organic traffic is not paid per click and compounds over time as rankings improve. The two disciplines address entirely different acquisition channels and require different tools.
Use Quantcast Measure if you are a publisher who wants free real-time audience demographic data for your site — understanding who your visitors are for advertiser media kits, monetisation strategy, or audience segmentation. Use Quantcast Advertise if you are a digital advertiser or agency buying programmatic display or video inventory and want AI-powered audience targeting using Quantcast's audience intelligence data. Use DeepSEOAnalysis if you need to diagnose why a page is underperforming in organic search, verify that your Core Web Vitals meet Google's ranking signal thresholds (CrUX p75 LCP ≤2.5s, INP ≤200ms, CLS ≤0.1), validate your structured data for rich result eligibility, or identify technical SEO issues affecting crawlability and indexing. Quantcast and DeepSEOAnalysis solve different problems for different teams — many organisations will use both for paid and organic channels respectively.
