Website Change Detection
Comparing versions of public web pages to identify meaningful additions, removals, and wording changes.
Last reviewed August 4, 2026What it means in practice
Websites are living strategy documents. Reliable detection needs stable extraction, before-and-after evidence, and filtering for navigation or cosmetic noise.
If this term cannot change a decision, sharpen the question or gather better evidence before doing more analysis.
A concrete example
A pricing page adds an implementation fee and removes self-serve signup; the captured diff shows a move toward higher-touch sales.
What to watch
Added or removed claims
Pricing and CTA changes
New audience or solution pages
How to use it well
- Start with the decision.Write down who needs to decide what, and by when.
- Separate evidence from interpretation.Keep the source, date, and observable fact attached to every conclusion.
- Turn the finding into a move.Update the message, battlecard, roadmap question, or watchlist—or explicitly choose not to react.
Common mistakes
Collecting without a question. More information creates more work unless it is tied to a decision.
Treating one signal as a strategy. Look for corroborating evidence and patterns before making a large response.
Losing the source. Unsourced competitive claims become stale, risky, and impossible for sales to defend.
