How to use WebScore
Everything you can do with WebScore — run audits, read your search data, fix DNS, set up monitoring, and connect it to your AI.
Getting started
Enter any URL and WebScore runs a real browser scan (Chromium + Lighthouse) across five dimensions — Performance, SEO, Accessibility, Security and Best Practices — plus domain metrics for authority. Each dimension gets a 0–100 score and you get an overall average.
Every scan gives you, per dimension:
- A score from 0–100, with history so you can track progress over time
- The specific issues found, ranked by severity
- Concrete how-to-fix guidance for each issue
Scanning and score previews are free. Unlock a scan's full report (all issues + fixes) for $3, or get Lifetime access ($29.99 one-time) for unlimited reports, monitoring, tasks, PDF exports, the API + MCP server, and AI UI/UX audits.
Performance
Performance is measured with Lighthouse driving a real Chromium instance, so you get lab-accurate metrics — not a guess.
- Core Web Vitals — LCP, CLS, and Total Blocking Time / interactivity
- Render-blocking resources, unused JavaScript & CSS, and main-thread work
- Image optimization (modern formats, correct sizing) and text compression
- Each finding includes its impact and exactly what to change
Tip: pair this with the free Performance and Image Compressor tools.
SEO
WebScore checks the on-page and technical SEO factors that actually move rankings:
- Title, meta description, canonical, robots directives and sitemap discovery
- Heading structure (single H1, logical hierarchy) and image alt text
- Structured data (JSON-LD) and its validity
- Open Graph & Twitter Card tags — including og:image for social previews
- Indexability, mobile-friendliness and broken-link detection
Search Console data
Connect Google Search Console to bring your real search performance into WebScore — alongside your scores, not in a separate tab.
Connect it:
- Open a website, go to Settings.
- Click Connect Google Search Console and authorize with the Google account that owns the property.
- WebScore pulls your data and keeps it in sync after each scan.
Once connected you can see:
- Clicks, impressions, average CTR and average position
- The exact queries your site ranks for
- Per-page and per-query breakdowns, with period-over-period comparisons
Search Insights
Search Insights turns raw numbers into direction. WebScore combines your Search Console queries with third-party authority data to show what to work on next.
- Keyword opportunities — high-impression, low-CTR pages worth optimizing
- Ranking trends over time so you can see whether changes are working
- Domain authority: Domain Rating (Ahrefs), Domain Authority (Moz) and Trust / Citation Flow (Majestic)
- Backlinks and referring domains
Domain authority data is refreshed at most once every 48 hours per website to keep it fast and current.
Accessibility
The accessibility audit checks your pages against WCAG so real users — and the law — are on your side.
- Color contrast against WCAG AA thresholds
- Image alt text, form labels and ARIA roles / attributes
- Heading order and landmark structure
- Keyboard focus and interactive-element labelling
Each violation is graded by severity with a specific fix.
UI/UX Audit (AI)
Beyond the automated checks, WebScore runs an AI-powered UI/UX audit — it captures real desktop and mobile screenshots of your page and sends them to Claude for a design-and-usability review, like having a senior designer look over your site.
- Real desktop + mobile screenshots captured with a live browser
- AI review of layout, visual hierarchy, readability, contrast, spacing and calls-to-action
- Annotated screenshots that point to each issue right on the page
- Prioritized, plain-English recommendations you can act on
- An overall UI/UX score to track alongside your other dimensions
AI UI/UX audits are included with Lifetime access.
Security
WebScore inspects the security posture attackers and browsers care about:
- SSL/TLS certificate — validity, issuer, expiry and chain
- HTTPS enforcement and security headers (HSTS, CSP, X-Frame-Options, and more)
- Email authentication — SPF, DKIM and DMARC
- DNS hardening — DNSSEC and CAA records
- Google Safe Browsing (malware / phishing) plus phishing heuristics
Check individual items any time with the free SSL Checker and Email Security tools.
DNS configuration
When a scan flags a DNS issue, WebScore gives you the exact records to publish at your DNS provider:
- Email deliverability — generate SPF, DKIM and DMARC records with the Email DNS Generator
- DNSSEC — enable signing at your registrar and publish the DS record so validating resolvers trust your zone
- CAA — restrict which certificate authorities may issue certificates for your domain
Generate records with the Email DNS Generator, then re-scan to confirm they resolve.
Monitoring
Turn on monitoring and WebScore re-scans your site on a schedule and alerts you when scores regress — so you catch problems before your visitors do.
- Open a website, go to Settings → Monitoring.
- Choose Daily or Weekly and save.
- Automated re-scans run each morning on your chosen cadence
- Email alerts when a score drops
- Historical trends show progress over time
Monitoring is included with Lifetime access.
MCP server
Plug WebScore into your AI as a Model Context Protocol tool — so Claude Desktop, Claude Code or Cursor can scan sites and read the results for you. It's a Lifetime perk.
Connect it:
- Go to Settings → API & MCP and copy your key.
- Add WebScore to your AI client's MCP config:
{
"mcpServers": {
"webscore": {
"url": "https://webscore.now/api/mcp",
"headers": { "Authorization": "Bearer <your-key>" }
}
}
}Then ask your assistant to “scan example.com with WebScore.” Scanning a new site through MCP also adds it to your account, so the results show up in your dashboard too. Available tools:
| scan_website | Run a full audit — scores, issues with how-to-fix, and domain metrics. |
| get_scan_report | Re-fetch the full report for a scan you already ran. |
| list_websites | List the sites in your account with monitoring status and latest score. |
| set_monitoring | Turn on daily/weekly monitoring for a site (or off). |
| check_ssl | Inspect a domain's SSL/TLS certificate and expiry. |
| check_email_auth | Check SPF, DKIM and DMARC for a domain. |
| get_page_metadata | Title, description, Open Graph (og:image) and JSON-LD structured data. |
| check_safe_browsing | Check a URL against Google Safe Browsing. |
| get_robots_txt | Fetch and summarize a site's robots.txt. |
| get_llms_txt | Fetch a site's llms.txt if published. |
