WordPress Glossary Plugin (CMTG) - Related Articles - What are They and How to Add Them

Term Related Articles

Back to User Guide


Related Articles are links that appear on your glossary term pages, which are responsible for referring the reader over to other pages or posts where that particular term has been used. They are available in the ProPro+ and eCommerce editions of the WordPress Glossary plugin.

TIP: When an Article is Related?

A page is considered a Related Article of a term when that term appears on it.

So, for instance, consider the term "WordPress". If the page has the term "WordPress" on it, that page will be considered a Related Article.

Index settings
  • Index rebuild interval / rebuild hour - Define if and when the index will refresh (higher frequencies can affect performance) (these options are not available in Pro version)
  • Post types to index - Specify which post types will contribute to the index (bigger selection can affect performance)
  • Related articles index rebuild chunk size - Set the chunk size of articles during the index rebuild (a high number can affect performance) (this option is not available in Pro version)
  • Rebuild Index! - Rebuild the index manually
  • Auto-add parsed pages to related articles index - If enabled, every time a page is accessed, it will be added to the index (can affect performance if enabled)

TIP: Improving Performance

Using the related articles feature increases the plugins use of memory and CPU processing. If you have more than 1000 articles you should consider the impact of this feature on your site performance.

To improve performance you can:

  1. Disable the automatic rebuild and do so only manually
  2. Reduce the interval time of the related articles rebuild.
  3. Show it only in terms and not in any kind of post posts.
  4. Disable auto-adding parsed pages to the index
  5. Controlling the chunk size - Since rebuilding the Glossary Index requires a lot of resources, both memory and time. It has to be done in chunks. The optimal size of the chunk depends on your server.

    If the page goes blank after clicking the button, try to make this value much smaller and try to rebuild it again.

  6. Removing part of the custom posts from the related article index.
