Site Sensei Capabilities and Standards
Why Is Your Website Not Performing?
Most websites have hidden issues that silently kill traffic, conversions, and search rankings. Here are the problems holding yours back.
Invisible to Search Engines
Missing meta tags, broken links, and poor keyword targeting keep your pages out of Google's index — costing you organic traffic every day.
Slow Load Times Drive Users Away
Slow page speed directly increases bounce rates and user abandonment. Poor Core Web Vitals hurt both user experience and search visibility.
Accessibility Issues Exclude Users
Missing alt text, low contrast, and keyboard traps lock out users with disabilities — and expose you to compliance risk.
No Clear Path to Improvement
Dozens of audit tools give you data dumps with no prioritization. You end up fixing the wrong things first, or fixing nothing at all.

Automated WCAG 2.1 scan detecting contrast failures, missing alt text, keyboard traps, and ARIA issues before your users do.
UI/UX Review
AI-powered design feedback on layout, typography, color usage, mobile responsiveness, and visual hierarchy.

Frequently Asked Questions
Everything you need to know about SiteSensei's website audit tool.
SiteSensei inspects websites across five core scored categories and six diagnostic modules: SEO (meta tags, headings, canonicals, schema), Performance (Core Web Vitals, asset loading), Accessibility (WCAG 2.1 compliance, contrast, ARIA), UI/UX (mobile responsiveness, tap targets, layout overflow), Code Quality (HTML structure, web standards), and Security (HTTPS, HSTS, CSP, clickjacking).
Yes. SiteSensei is 100% free during our V1 launch. You get full access to all six analysis modules, Core Web Vitals diagnostics, and AI-prioritized remediation plans at zero cost — no credit card required and no artificial quotas.
Audits are processed through an automated multi-stage pipeline. The worker crawls the target URL, extracts DOM and network metrics, runs accessibility and security analyzers, and generates an AI-prioritized remediation report as soon as processing concludes.
Google Lighthouse is a single-page performance tool. SiteSensei goes further: it combines SEO, performance, accessibility, UI/UX, code quality, and security into one scan, then uses AI to prioritize issues by impact and give you specific fix instructions — not just scores.
Not at all. Just paste your URL and click Analyze. The report explains every issue in plain language with step-by-step fix instructions. Developers get the technical detail they need, while non-technical users get clear, actionable guidance.
Yes. You can analyze any publicly accessible URL. This is useful for benchmarking your site's SEO, performance, and accessibility against competitors in your space.
Core Web Vitals are Google's three key metrics for measuring user experience: Largest Contentful Paint (loading speed), Interaction to Next Paint (interactivity), and Cumulative Layout Shift (visual stability). Google uses them as ranking factors, so poor scores directly impact your search visibility.
Absolutely. SiteSensei only analyzes publicly accessible content — the same information any visitor or search engine can see. We do not store your credentials, access private pages, or share your audit results with third parties.
