What SEO4Ajax is
SEO4Ajax uses dynamic rendering to make AJAX content visible to search engines and social networks. It says 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. A REST API supports customization and automation, while its 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 flag quota overages, scraping errors or an unreachable website. SEO reports identify indexing issues such as broken links, duplicates and invalid hreflang tags; these are included in premium versions of paid plans. It lists compatibility with Google, Bing and Yandex, as well as Facebook, Twitter and Flipboard, and links to a Chrome companion extension. The free Developer plan allows 1,000 pages and 2,500 snapshots per month with community support.
