ReaderNook Lab · SEO, accessibility, security
Audit a public web page for search metadata, technical health, accessibility basics, security headers, content quality, performance signals, and optional same-site crawl checks.
SEO Checker reviews a public page and turns common audit signals into a clear report. Enter a URL to check metadata, headings, crawlability, accessibility basics, security headers, content signals, and performance-style HTML clues.
The workflow is simple: scan one page first, then optionally crawl a small set of same-site pages to find repeated titles, missing descriptions, broken links, and other practical fixes.
The scores are practical indicators, not official search engine rankings. A high score means the page passed many common checks, while a lower score points to issues worth reviewing, such as missing metadata, crawl problems, accessibility gaps, or security header warnings.
Yes. The entered page URL is scanned first. If same-host crawling is enabled, the tool also checks a limited number of linked pages on the same host.
It follows internal HTML-looking links found from the scanned page and checks up to the selected page limit. This can help find duplicate titles, missing meta descriptions, missing H1 headings, and broken internal links.
The tool analyzes the HTML returned by the server. If important text or metadata is added only after JavaScript runs in the browser, it may not appear in the scan results.
No. The scores are practical audit indicators based on common SEO, technical, accessibility, security, content, and performance-style checks. They help prioritize fixes but do not predict rankings.
It compares visible text size with the full HTML response size. A low ratio is not always bad, especially if the page has enough useful text, but it can hint at heavy markup, scripts, or hidden boilerplate.
Yes. You can copy a summary, export issue data as CSV, export crawl data as CSV, export the full report as JSON, or print/save the report as a PDF.
