Check responsive signals, readability, spacing, and interaction quality. Spot issues affecting users, speed, and rankings. Turn technical checks into clear actions for stronger pages.
Review viewport setup, spacing, readability, load behavior, stability, and intrusive elements to estimate how well a page serves mobile users.
Fill the fields below, then submit to calculate a weighted mobile friendliness score and view the graph above the form.
This calculator uses a weighted scoring model. Each mobile quality area receives a 0 to 100 score, then the tool applies issue penalties.
Base Score = (Viewport × 0.10) + (Responsive × 0.14) + (Tap Targets × 0.11) + (Fonts × 0.10) + (Media × 0.09) + (Touch Spacing × 0.09) + (Accessibility × 0.09) + (Load Performance × 0.12) + (CLS Stability × 0.08) + (Page Weight × 0.08)
Total Penalty = Overflow Penalty + Blocked Resource Penalty + Interstitial Penalty
Overall Score = Base Score - Total Penalty
| Page | Viewport | Responsive % | Tap % | Load Time | CLS | Weight MB | Overflow | Blocked | Interstitials | Final Score | Rating |
|---|---|---|---|---|---|---|---|---|---|---|---|
| /summer-sale | Yes | 94 | 91 | 2.80 | 0.09 | 1.90 | 0 | 1 | 0 | 87.42 | Good |
| /blog/mobile-seo | Yes | 88 | 84 | 4.30 | 0.19 | 2.80 | 1 | 3 | 0 | 70.86 | Needs Improvement |
| /checkout | No | 74 | 72 | 6.20 | 0.31 | 4.70 | 3 | 5 | 1 | 39.55 | Poor |
It estimates mobile usability by combining responsiveness, readability, tap targets, stability, load behavior, page weight, and disruptive elements into one weighted score.
No. It is a practical scoring model for planning and review. It helps prioritize improvements, but it does not replace live crawl data or field metrics.
Some issues harm usability more directly than percentages alone show. Overflow, blocked resources, and intrusive overlays can quickly damage the mobile experience, so the model subtracts penalty points.
Scores above 90 are excellent. Scores from 75 to 89 are good. Scores from 60 to 74 need improvement. Below 60 usually means urgent mobile fixes are needed.
Slower pages reduce usability, engagement, and conversion potential on mobile devices. The calculator rewards faster experiences and lowers scores when load time becomes heavy.
Use audits, manual review, device testing, or page templates. For example, if 9 of 10 buttons meet spacing rules, enter 90 for touch spacing.
Yes. Homepages, articles, product pages, tools, and checkout pages can all be tested. The selected page type mainly helps describe the report context.
No. Rankings depend on many factors, including relevance, authority, and content quality. A strong mobile experience still supports users and can reduce avoidable technical friction.
