## Description

Seoly is a professional SEO crawler and analysis tool for Firefox that helps you audit websites directly from your browser. It crawls pages, images, PDFs, JavaScript, CSS and other resources, then presents the results in a clear dashboard with status codes, page titles, meta descriptions, canonicals, indexability, load times and page sizes.

The add-on helps detect common SEO and technical issues such as missing titles or descriptions, missing H1 tags, thin content, duplicate content, noindex pages, canonical problems, broken URLs, redirects, mixed content, missing image alt text and slow-loading pages. It also analyzes internal and external links, anchor texts, nofollow links, orphan pages, hreflang tags, <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/9d9f25684d519afe48ff10aa160c7c6a1518646069374f4f4458fe60a3717c84/http%3A//Schema.org" rel="nofollow">Schema.org</a> data, sitemap structure and differences between crawled pages and sitemap URLs.

Seoly includes configurable crawl settings such as maximum URLs, crawl depth, parallel requests, include/exclude filters, parameter handling, robots.txt support, sitemap crawling, subdomain crawling and optional external link checks. Results can be filtered, sorted, inspected in detail and exported as CSV, JSON or an HTML sitemap mindmap.
