SEO4Ajax vs Siteliner

SEO4Ajax uses dynamic rendering to make AJAX content visible to search engines and social networks. It can be configured on Apache, nginx, PHP, Java EE, Ruby, Python and Node.js servers, and supports frameworks including React, Vue.js, Angular, AngularJS, GWT, Ember and Backbone. The service says it can handle thousands or millions of pages without website code changes. Its REST API supports customization and automation, while a dashboard tracks bot activity, cache freshness, duplicates and broken links. SEO4Ajax caches snapshots, can capture inner links, and supports custom recache periods and email alerts for quota overages, scraping errors or unreachable websites. SEO reports flag indexing issues such as broken links, duplicates and invalid hreflang tags. The Developer plan is free, with 1,000 pages and 2,500 snapshots per month. Paid plans start at $29/mo (annual), and include email support at listed response times. The service is for business use, not personal, family or household use.

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.
