How does the comparison work?
You can check 3 different homepages per rolling 24 hours. Compare A+B+C together or start with A+B and add C later. Reusing a website already checked today does not use another slot. People on the same network may share the allowance.
Yes. Use Remove next to the additional fields to leave just Website A. Scores, technology and observations are also available for a single website. Use Add website to return to a comparison.
Yes. View the score and main differences without an email. Detailed access requires your email and the checkbox requesting the report and allowing individual contact about the analysis and an improvement offer. No spam or newsletter. The email link opens the report directly. You can withdraw permission for future contact at any time by emailing kontakt@ercoding.pl, without losing existing report access.
The score combines speed (30%), usability (30%), search readiness (20%), basic safeguards (15%) and privacy signals (5%). An overall score requires at least 90% measurement coverage, data in every category and at least 75% speed coverage including an actual speed measurement. Otherwise, we show the available findings without an overall score. Missing data is not a failure and AI does not assign points.
When the measurement browser can open the page, AI can review mobile and desktop screenshots alongside public content and measurements. It looks at readability, visible contact options, buttons and useful visitor information. AI observations are labelled and may be wrong. “No menu found on the homepage” does not mean a restaurant has no menu anywhere on its website. We do not judge brand compliance without brand guidelines.
Each completed website appears while the others are still being analysed. Missing measurements are described explicitly. If you leave the tab, return to this tool in the same browser and choose Resume analysis. We continue from the last saved step; reusing a reservation within its 24-hour window does not use another slot. A request already in progress may finish after you leave, but further steps resume when you return. If browser storage is unavailable, keep the report link or enter the same website addresses again.
Report access lasts up to 30 days. Restricted admin history keeps reports, scores and current report/contact requests for up to 12 months; request IP addresses for 30 days. You can request deletion or withdraw contact permission at kontakt@ercoding.pl. Google receives the public website URL; OpenAI receives selected evidence and available screenshots. Retention exceptions, including withdrawal records, are described in the privacy policy and terms.
No. First you see the same evidence-based results for websites A, B and C. You can then optionally choose your own website and confirm the choice. Only the wording and advice change, never the points or ranking. You can undo the choice. This preference is remembered in the current browser session; a shared report link remains neutral.
