Ref Hub WordPress Plugin, OpenGraph Bot - Collect and Share Internal and External Sitemaps and URLs.
Ref Hub is a Link Hub that manages OpenGraphs as a WordPress plugin. These are loaded both internally and externally via a batch bot, either manually or automatically twice daily. Sitemaps or URLs can be intelligently controlled and read out. Parent and child elements make the collection structurable, allowing it to be filtered and searched by categories. The display allows for og:image, Title, Description, and URL or Slug fragments, as well as Ref Hub categories. All data can be locked against overwriting and modified by yourself. The system allows for infinity scrolling and also provides its own sitemap. It reliably detects errors in OpenGraph usage, thus ensuring clean content.

Ref Hub WordPress Plugin
Ref Hub stands for Reference Distributor and could also be called Link Hub. In programming, however, the term Referer, i.e., more of an origin distributor, is also known. It is therefore about collecting and presenting data. OpenGraph has proven particularly useful in this regard, as it provides all important data for a link.
Like Pages and Projects, the WordPress plugin provides two dedicated areas in the Dashboard. The Ref Hub, which manages and catalogs internal and external links, sitemaps... via JSON. As well as Ref Items, which lists the found entries and makes them editable.
Why OpenGraph as a WordPress Projects Replacement?
Projects is a great hook in WordPress; you can also use it multiple times with tricks and display it very easily. However, they have problems when a website is operated across multiple levels (link depth). Likewise, no external data can be included in projects, so the maintenance effort can be very high. This is exactly where Ref Hub comes in and practically completely replaces Projects. With other plugins like SEO-Link-Image, very dynamic websites can be created. Missing OpenGraphs are now visible, so your website gains overall quality.
Category and Search for better User Experience.
Ref Hub can map websites, references, and all other content into categories. Each item can also belong to multiple categories. This way, websites can be shown in references, or external press reports can also appear in references. It thus allows for dual use of content that might otherwise not be discoverable.
All content that an OpenGraph contains can also be searched by name, and it can, of course, also be filtered by categories. For this, there are additional shortcodes that can also be embedded on other pages. Ref Hub can also be used multiple times on pages and, for example, pre-filtered by a specific category.
Purchase and Implementation of the Ref Hub WordPress Plugin
Ref Hub was only completed in November 2025 and can be obtained at https://www.dirschl.com. You will also receive the necessary support here to ensure the plugin runs securely and all your JSON data functions properly. The one-time setup costs 499 EUR. The plugin had a high development effort and is specially adapted for WordPress users who, for example, are redesigning their website but need to retain content from the old website.
