Methodology & Data Sources

Data Sources

Video and channel data are collected from the YouTube Data API v3. Paid promotion data is cross-referenced against the Google Ads Transparency Center. Politician roster data comes from public congressional records. Channel-to-politician associations are verified through a combination of official sources and manual review. Video content is analyzed using AI to categorize topics, messaging strategies, and production quality.

Coverage

PoliYT tracks all current members of the US Congress (Senate and House) and sitting governors who maintain YouTube channels — 588 politicians across 740+ channels and 72,000+ videos.

Many officials maintain multiple channels — typically an official government channel and a campaign channel. We track both types and attribute them to the same politician, since campaign channels often reveal different engagement patterns than official ones.

Methodology

Data Collection

An automated pipeline runs nightly to discover new videos, record metadata, and snapshot performance metrics across all tracked channels. View counts are tracked daily, giving us a time-series view of how political content performs over time. Videos are also analyzed for paid promotion signals and content characteristics.

Leaderboard

The leaderboard ranks politicians by organic views on videos published within the last 30 days. Videos identified as having paid promotion are excluded from rankings so the leaderboard reflects genuine audience interest, not ad spend.

Weekly Reports

Weekly reports cover Monday through Sunday and highlight the top-performing political videos and fastest-growing channels from the previous week, with paid and organic performance reported separately.

Content Analysis

Videos are analyzed using AI to identify topics, messaging strategies, tone, production style, and other content characteristics. This powers content breakdowns on politician profiles and helps surface patterns in what works on political YouTube.

YouTube Shorts

Short-form videos (Shorts) are identified and tracked separately from long-form content. Both formats are included in statistics, with format-level breakdowns available on politician profiles.

Paid vs. Organic Views

One of PoliYT's core capabilities is distinguishing organic video performance from paid promotion. Many politicians run YouTube ads that can inflate view counts by orders of magnitude, making raw view totals misleading.

We use a multi-signal approach that combines behavioral analysis of video performance patterns with verified ad spend data from the Google Ads Transparency Center. Videos flagged as paid are separated in rankings and reporting so that organic reach — the audience a politician earns without paying for it — is always visible.

This distinction matters because a video with 2 million paid views and a video with 200,000 organic views tell very different stories about a politician's actual YouTube presence.

Update Frequency

Data is refreshed daily. New videos are typically captured within 24 hours of publication, and the site is regenerated each morning.

Limitations

PoliYT is a data-tracking platform, not an endorsement system. Please consider these limitations when interpreting the data:

• Paid detection is conservative. Our paid promotion detection cross-references multiple data sources, but some paid campaigns may not appear in public transparency records. When in doubt, we err on the side of not flagging a video as paid.
• Coverage is not exhaustive. Some politicians may have YouTube channels we haven't identified yet. If you spot a missing channel, please let us know.
• Subscriber counts are rounded by YouTube and may not reflect exact figures.
• YouTube API limits mean some metadata may lag behind real-time figures by up to 24 hours.

Research Context

The growth of YouTube as a political news platform is well-documented by nonpartisan research:

These trends make YouTube a critical — and often overlooked — battleground for political communication. PoliYT exists to bring transparency and data to this space.
