FAQPage Schema
How do I check my website pages for missing meta tags?▼

Run the seo_checker.py script against your project directory. It scans HTML, JSX, and TSX page files and reports missing title tags, meta descriptions, and Open Graph tags per file.

What SEO issues does an automated page audit detect?▼

The audit detects missing title tags, missing meta descriptions, missing Open Graph tags, multiple H1 headings on one page, and images with missing or empty alt attributes.

Does the SEO checker work with React and Next.js projects?▼

Yes, it scans JSX and TSX files in pages, app, routes, views, and screens directories. It skips utility files like hooks, services, configs, and test files to focus on public-facing pages.

What are the Core Web Vitals targets for good SEO?▼

LCP should be under 2.5 seconds for loading performance, INP under 200 milliseconds for interactivity, and CLS under 0.1 for visual stability. These metrics are measured with PageSpeed Insights.

Why does the SEO checker skip some of my files?▼

Files in directories like node_modules, tests, or docs are excluded, as are files matching utility patterns like config, hook, service, or spec. Only files identified as public pages are analyzed, up to 50 files.
