Actions to review
The filter applies on screen only; the PDF and the copied summary keep every action.
Automated checks help spot some issues, but they do not replace a human review and guarantee neither search ranking nor the absence of defects.

Your saved reports
Up to five reports saved in this browser. Pick two audits of the same page and device to compare scores and findings, then print the result. They are not synced, and a change of domain does not carry them over automatically.
To compare, choose two audits of the same page and device.
A different way to audit
From a list of issues
to a clear action plan.
WebCheck turns Lighthouse results into accessible explanations, visible priorities and next steps to review with your client.
The right actions first
A clear order of priority separates useful improvements from details that can wait.
See an example →A report that moves things forward
Share a professional snapshot and turn findings into concrete next steps.
For your agency → A more useful report
Every finding comes with what to do next.
A report should not leave your client facing a list of technical terms. It should help them understand the situation and decide on the next action.

ACTIONS TO REVIEW
PerformanceHigh priority
Several images could be lighter
Large image files can slow down loading on mobile.
Compress images and prefer modern formats such as WebP or AVIF, keeping a quality suited to their display.
SEOMedium priority
The home page title could be more specific
A descriptive title helps visitors understand what the page is about.
Write a unique title that describes the business and the main topic of the page.
AccessibilityTo check
Some text contrast should be checked
Good contrast makes reading easier for more visitors.
Check text and background colours with a contrast tool, then adjust the shades if needed.

Results to use with judgement
Clarity also starts with honesty.
Automated checks can help spot some issues. They do not replace human expertise and guarantee neither a better ranking nor the absence of defects.
Frequently asked questions
Before you run an audit.
What WebCheck analyses, what the results mean and what happens to your URL.
Read the data detailsWhat is analysed?
WebCheck asks Google Lighthouse to evaluate a public page for performance, accessibility, best practices and SEO. Each audit covers a single URL; it is not a crawl of the whole site.
Why do mobile and desktop results differ?
Choose “Both” to get both reports in a single audit. Each mode uses a different simulation and different loading conditions. Scores can also vary between two audits; they are an indicator, not an absolute measure of every visitor’s experience.
Does a good score guarantee good SEO or an accessible site?
No. Automated checks only cover some criteria. A score guarantees neither a position in search engines, nor compliance, nor the absence of issues.
Is my URL or my report stored?
Without an account, WebCheck does not keep your reports: a result may only stay 15 minutes in the Cloudflare cache. With an account, we keep your email address, your name and your number of analyses per day, never the audited addresses. If you choose to, you can save up to five reports in this browser to compare them; they are not synced. The PDF stays on your device. Details in Data and privacy.
Who receives the page address?
The URL is sent to Google PageSpeed Insights to run the audit. Do not submit private links, access tokens or URLs containing confidential information. See the Data and privacy page.
Why can an audit fail or be limited?
The page may be unreachable by the analysis service, or the Google API may be temporarily unavailable. The number of analyses is also limited each day: 5 without an account, 15 with a free account and 200 with Pro (a “Both” audit counts as two). Check that the page is public, then try again a little later.
What is the difference between Free and Pro?
The free plan allows up to 15 analyses per day with an account. Pro, from $9 per month, raises the limit to 200 analyses per day for your client work, with no commitment: cancel anytime and get a full refund within 14 days of your first payment. See pricing.
How do I keep or share the report?
After the audit, choose “Print / save as PDF” and use your browser’s PDF option. The file stays under your control; WebCheck does not create public share links in this version.
