Revenue-Weighted PSI
A site-wide PageSpeed average tells you what your tracked URLs look like on paper. Revenue-Weighted PSI tells you what your actual users experience — by weighting every URL's mobile PageSpeed score by its real 28-day click volume.
Why it matters
If your slowest pages happen to be your most popular ones, your simple average looks healthy while Google's Page Experience signal sees a slow site. The gap between the two scores is the vanity gap — and it's almost always negative on real sites.
What it measures
- Simple PSI average — the mean mobile performance score across every tracked URL with a recent PSI run.
- Revenue-weighted PSI — $\dfrac{\sum (\text{score}_i \times \text{clicks}_i)}{\sum \text{clicks}_i}$ across the same URLs, weighted by their 28-day clicks from Search Console.
- Gap — the difference. Negative means popular pages are slower than the tail.
How to read the table
The "Δ vs Weighted Avg" column shows whether each URL is dragging the weighted score down (red, negative) or pulling it up (green, positive). Combined with the clicks column, you instantly see which URLs to prioritise: high clicks + large negative delta = top of the backlog.
When to use it
- Quarterly reviews — replace "average mobile score" with the weighted score in your dashboards.
- Before allocating engineering time — confirm fixes will move the metric your visitors actually feel.
- After deployments — a small change to a high-traffic page will move the weighted score even when the simple average stays flat.
Data requirements
- PSI runs (mobile strategy) for at least some tracked URLs.
- GSC ingestion of
gsc_page_dayfor the last 28 days.
