SEO4Ajax
Rennes, France
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 and libraries such as React, Vue.js, Angular, AngularJS, GWT, Ember, and Backbone. The service says it can handle thousands or millions of pages without changes to website code. Its REST API supports customization, automation, and closer website integration, while a dashboard tracks bot activity, cache freshness, duplicates, and broken links. SEO4Ajax caches snapshots, can capture inner links, and allows custom recache periods. Email alerts can cover quota overages, scraping errors, or an unreachable website. SEO reports flag indexing issues including broken links, duplicates, and invalid hreflang tags; reports are included in premium versions of paid plans. Compatibility is listed for Google, Bing, Yandex, Facebook, Twitter, and Flipboard, and the service links to a Chrome companion extension. The free Developer Plan allows 1,000 pages and 2,500 snapshots per month, with community support. Paid plans start at $29/mo (annual).
