Page Speed Risk Predictor

Fast pre-audit that estimates speed risk before full Lighthouse testing.

How to use this predictor for real performance triage

Page speed work often gets stuck between two extremes: either teams ignore performance until rankings and conversion drop, or they jump straight into heavy audits for every page and lose a week without clear priorities. This predictor is designed for a faster middle path. It reads lightweight HTML architecture signals (document size, script density, stylesheet count, image volume, lazy-loading hints) and gives an immediate risk tier you can use to decide where deeper profiling will actually pay off.

The most practical use-case is weekly template sampling. Run this on homepage, one category page, one product or transactional page, and one editorial template. If a page lands in medium or high risk, route it into deeper checks first instead of running broad optimization projects. That keeps engineering focus tight and avoids over-optimizing low-impact pages. After any deploy that touches scripts, tracking tags, CMS blocks, or media rendering, rerun the same URLs and compare movement before and after release.

This tool is not a replacement for Core Web Vitals or real-user telemetry, but it is excellent for sprint planning. Use it to choose one template, ship one targeted performance fix (for example script reduction or image lazy-loading policy), then validate with HTTP Header Inspector and a full lab audit. That one-fix loop keeps speed work measurable and prevents multi-change noise.

Practical FAQ

Can this score replace Lighthouse or CrUX?

No. It is a triage shortcut. Use it to prioritize where to run deeper Lighthouse and real-user metric analysis.

Which pages should I test first?

Start with templates that drive revenue or organic entry traffic: homepage, top categories, key product/service pages, and high-traffic articles.

How often should I run this?

Run weekly and after any deploy that changes page composition, scripts, media strategy, or rendering behavior.
