The stated plan details make the differences in project, competitor, keyword, and backlink capacities explicit, while all paid options are billed annually.

Siteliner is a web and API service that crawls a website for quality issues, including internal duplicate content and broken links. Its duplicate-content check highlights matching material on pages while excluding common elements such as menus and navigation. The service flags broken internal links and identifies pages prominent to search engines from link patterns across the site. Reports include site and page results, a standard XML sitemap, and CSV downloads for the site report and currently displayed table. The Premium API can start scans and return results in JSON, with PHP and Python sample code. Starting an API scan costs 1c per page scanned, and each result request costs 1c. Siteliner requests four pages at a time. It reads publicly accessible pages unless non-logged-in requests from its servers are allowed. Summary reports remain available for 185 days; highlighted links, duplicate content, and cached pages remain for 60 days. The free plan covers 250 pages once every 30 days.
