§ 04 · faq
Questions, answered.
What is an on-page SEO audit? +
An on-page SEO audit checks everything on a single page that affects how search engines read and rank it: the title and meta description, heading hierarchy, canonical URL, robots directives, structured data, internal links, image alt text, and page speed. It is narrower than a full site crawl - you audit one page at a time and fix what that page gets wrong. LintPage runs 60 such checks on any URL in about 30 seconds.
What is a website audit tool? +
A website audit tool automatically scans your site for technical issues that affect search engine rankings, user experience, and security. It checks things like meta tags, page speed, broken links, SSL certificates, and accessibility — then gives you a prioritized list of what to fix.
How do I audit my website for SEO? +
Paste your URL into LintPage and click "Scan". In about 30 seconds you'll get a detailed report covering 60 checks across SEO, performance, security, and accessibility. Each issue includes a severity level and a plain-English explanation of how to fix it.
Is LintPage free? +
Yes.
What does a website audit check? +
LintPage checks 6 categories: SEO essentials (titles, meta descriptions, headings, canonicals), social sharing (Open Graph, Twitter Cards), crawlability (robots.txt, sitemaps, broken links), performance (TTFB, render-blocking resources, image optimization), security (SSL, mixed content, security headers), and accessibility (alt text, ARIA, semantic HTML).
How is LintPage different from Lighthouse CI? +
Lighthouse CI runs Google's Lighthouse audits in your pipeline — performance, basic SEO, accessibility, best practices. LintPage focuses on the deployment disasters Lighthouse misses: AI crawler accessibility (does ChatGPT/Claude/Perplexity actually receive your page?), staging URL leaks into Google's index, OG tag regressions across redesigns, schema markup breakage. Plus the catastrophic basics — that stray noindex tag — caught BEFORE they ship. We complement Lighthouse CI; we don't replace it.
Can I use LintPage in my CI/CD pipeline? +
Yes. You get access to the LintPage CLI, which you can run in your CI/CD pipeline to automatically audit pages before every deploy. It supports GitHub Actions, GitLab CI, and any environment that runs Node.js.
