What This Workflow Does

- Parallel page scraping — Fetches your page and the competitor's page simultaneously so you get results faster, not one site at a time - HTML cleaning — Strips all scripts, ads, and navigation clutter from both pages, leaving only the actual content GPT-4o-mini needs to compare - Content gap identification — AI pinpoints exactly which topics, subtopics, and questions your page is missing that the competitor already covers - Competitive advantage mapping — Surfaces what your page has that the competitor lacks, so you know what to protect and promote - Priority action list — Delivers 5 concrete, ranked improvements specific to your page — not generic SEO advice - Token-efficient processing — Caps each page at 8,000 characters so every run stays fast and API costs stay predictable - Slack report delivery — Posts the full 6-section analysis with business name, keyword, both URLs, and run date directly to your team channel — ready to act on or forward to a client
