SubExtract for Marketers

Competitor channel audit

1. 1Use Channel Videos to pull the full upload history for a competitor — titles, view counts, publish dates
2. 2Sort by view count to surface their top 20 performers and identify thematic clusters
3. 3Extract transcripts from the top performers to map their messaging, hooks, and content angles
4. 4Pull the comment sections to mine the language their audience actually uses
5. 5Output a competitor brief: themes, hooks that work, audience-language phrases, content gaps you can exploit

Content trend tracking on TikTok and Instagram

1. 1Build a watchlist of 10–20 competitor accounts on TikTok and Instagram in your niche
2. 2Extract transcripts and captions from their recent posts at scale
3. 3Scan the corpus for recurring hooks, opening lines, and CTA structures
4. 4Catalog the patterns by theme and platform — track which formats are gaining traction week over week
5. 5Feed the recurring hooks into your own creative briefs before they peak

Customer voice mining

1. 1Identify videos where your target audience is concentrated — competitor content, review videos, niche tutorials
2. 2Extract comments to CSV across that corpus
3. 3Sort by like count and filter for questions, complaints, and recurring phrases
4. 4Pull verbatim language — exact words, exact objections, exact desires — into a swipe file
5. 5Drop the verbatim phrases into ad copy, landing page headlines, and email subject lines

Mapping a competitor's full catalog and theme distribution

Pull a competitor's entire upload history — say, 340 videos. Cluster the titles into 8–10 themes (product reviews, how-tos, opinion pieces, comparison videos). Cross-reference with view count to see which themes drive the most traffic. You now know exactly which content angles their audience rewards — and you can either match the bets that work or attack the gaps they're ignoring.

Mining customer-voice phrases from comment sections for ad copy

Export 2,000+ comments across the top 5 videos in your niche. Scan for repeated phrases — the exact words people use to describe the problem, the desired outcome, the frustration. Lift those phrases verbatim into your headlines and primary text. Ad copy written in your prospect's own language outperforms anything you'd write from scratch.
