What it is

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.
