Buy Pages Worth Showing Up On

Standard verification tells you an ad was viewable. It does not tell you the page carried thirty other ads, refreshed
twice while the user scrolled, or took nine seconds to render. DeepSee.io measures the experience around your ad,
not just whether it technically appeared.

Know How And Where An Ad Is Served

Density Across the Whole Journey

DeepSee aggregates ad density into three stages of the user journey- initial, mid, and final, and reports above-the-fold, in-article, average, and peak density with percentiles. A high peak-to-mean ratio is a red flag for sites that look clean on a first visit but stuff ads once they detect paid traffic.

Refresh, Formats & Intrusiveness

We measure ad-unit refresh rates, detect disruptive formats like floating video players and pop-ups, and track redirects, the patterns users actually notice and that erode campaign performance. Responsible refresh schedules register as a positive quality signal; rapid refresh registers as risk.

Real Page-Experience Data

DeepSee incorporates real-world Core Web Vitals from the Chrome UX Report- LCP, INP, and CLS, alongside page weight and request counts, connecting ad implementation to the loading and stability metrics publishers and platforms already optimize for. This grounds "good experience" in field data, not lab
