đź’ˇ SaaS Idea: SERPscope: AI SEO Change Journal + Impact Tracker

A crawler that snapshots on-page elements every 15 days, diffs changes, and correlates with rank/traffic shifts. Generates explainable AI summaries of what changed and likely impact. Ideal for in-house SEOs and agencies proving work-to-outcome links.

Platform: web

Why it's a good idea?

Problem & Proposed Solution

In-house SEO teams and agencies need to prove the impact of on-page changes on rankings / traffic. Existing rank-trackers tell you what moved, but rarely why. SERPscope promises to:

  • Crawl every page snapshot (e.g. every 15 days)
  • Diff HTML/content/technical fields (title, h-tags, schema, CWV, internal links, etc.)
  • Overlay diffs with rank + GSC / GA traffic curves
  • Auto-generate AI “change journals” that explain possible causality for clients / managers.
