Why doesn’t the Video SEO plugin index videos on my category page?

The Cause

The Video SEO plugin only indexes videos on your taxonomy pages that are in the description of that taxonomy. If the videos are in shown as excerpts of underlying pages, it will not index them.

The Solution

If indexing the videos in descriptions of taxonomy pages is exactly what you want, you should check the taxonomies you want indexed by ticking these taxonomies under the SEO-Video-‘Taxonomies to include in XML Video Sitemap’ section.
