BBP Improvements for yoast
One possible solution is to use a plugin called BBP Improvements for Yoast which is a helpful tool to make Yoast wordpress seo support bbpress better. You can install and activate this plugin from your WordPress dashboard and see if that helps.
Another possible solution is to use the excerpt variable in the Admin > SEO > Search Appearance > Content Types (tab) section. There you will have a ‘Topics (topic)’ section where you can add a default meta description using the excerpt variable. This will automatically output the first part of every topic as the meta description.
What are you talking about “Admin > SEO > Search Appearance > Content Types (tab) section” – are you talking about Yoast (I find nothing like that) or bbpress (I find nothing like that)..
/Thanks.
Has anyone solved this? BBP Improvements for Yoast didn’t work for me. Surely it should be possible to edit the meta tags on the forum home page (e.g. https://example-site.com/forums)?
