Concrete CMS is a flexible open-source CMS, but it has no ready API to publish posts into a blog. Sorank still gives you a fully automated SEO blog on your own domain.
Concrete CMS exposes a REST API mainly for configuration and management, not turnkey blog publishing, and the available endpoints depend on your version and the add-ons you install. Rather than build and maintain that custom integration, you let Sorank host the blog for you, ready in minutes.
Sorank publishes and hosts your articles on your own subdomain, for example blog.yourdomain.com, linked from your Concrete CMS site. Every post strengthens your domain authority.
Full walkthrough: Host your blog on Sorank. Reference: Concrete CMS REST API endpoints.
Add a Blog link in your Concrete CMS navigation pointing to your hosted blog subdomain. Visitors move smoothly between your main site and your blog, and Google indexes both under your domain.
Can Sorank publish directly into Concrete CMS? No. Concrete CMS has no standard blog publishing API, so Sorank uses its own hosted blog instead.
Do I keep my content if I leave? Yes. Export your whole blog any time and re-import it elsewhere. Your content is always yours.
Does the hosted blog cost extra? No, it is included in your Sorank subscription.
