Features & Capabilities

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, Schema.org 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.

Is Seoly Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Seoly requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Seoly is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
