§ 04 · faq

Questions, answered.

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 45+ 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 Semrush or Ahrefs? +

LintPage is built specifically for pre-launch checks. While Semrush and Ahrefs are comprehensive SEO suites for ongoing optimization (at $129-140/month), LintPage focuses on catching critical issues before they go live — in 30 seconds, for free. Think of it as a linter for your website.

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.
