What SEO4Ajax 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 lists support for frameworks and libraries including React, Vue.js, Angular, AngularJS, GWT, Ember, and Backbone. The service says it can work with thousands or millions of pages without requiring website code changes. A REST API supports customization, automation, and closer integration with a website. Its dashboard reports bot activity, cache freshness, duplicates, and broken links. SEO4Ajax caches snapshots, can capture inner links, and supports custom recache periods; email alerts can cover quota overages, scraping errors, and unreachable websites. SEO reports flag indexing problems such as broken links, duplicates, and invalid hreflang tags. The service lists compatibility with Google, Bing, and Yandex, along with Facebook, Twitter, and Flipboard, and links to a Chrome companion extension. Plans range from a free Developer Plan with 1,000 pages and 2,500 snapshots per month to paid plans from $29/mo with annual commitment. SEO4Ajax is offered for business use, and its maker, Capsule Code, is based in Rennes, France.
