Siteliner

Siteliner scans your site for internal duplicate content, broken links and technical SEO issues in seconds. It's a fast, free tool for a first-level SEO diagnosis, developed by the same creators as Majestic.

Siteliner is a technical SEO analysis tool that scans a website and identifies the main issues that may affect ranking. The generated report highlights internal duplicate content — site pages that are too similar to each other, a negative signal for Google — non-functioning internal links, blocked pages, redirects and other technical anomalies. All in a simple visual format, with a content uniqueness percentage for each page. Siteliner is developed by the same team as Majestic, with a solid technical SEO background. The free version scans up to 250 URLs per month; the Premium plan increases this limit and allows more frequent scans. It's a simple, immediate tool for a first site diagnosis, less comprehensive than Screaming Frog but faster for a quick check.

For SEO specialists, webmasters and site owners who want a quick diagnosis of duplicate content, broken links and technical SEO issues without configuring complex tools.

Siteliner is free for scans up to 250 pages per month. The Premium plan starts at $7.50 per month and increases the page scan limit and scan frequency. It's one of the SEO tools with the best free-to-utility ratio available.
