There are some excellent SEO plugins out there, but the question is which ones play well with bbPress. The best way to find out is to install them and give them a go.
Personally, I recommend Yoast SEO or All-in-one SEO as I believe those are the two best.
Thanks for the prompt reply. I already have the All-in-one SEO plugin (and activated for my blog), but I don’t really see any option to change/modify forum META titles.
bbPress overrides the page titles. See what I posted in the other topic.
Yoast looks pretty good. And he works hard at compatibility with other plugins. Give it a go (there’s an import tool for All-in-One SEO)
You can use https://wordpress.org/extend/plugins/seo-data-transporter/ to move SEO settings around from plugin to plugin, this is what I would recommend to use.
In theory all SEO functions should work in bbPress *except* the page title because bbPress filters that.
Closing this topic as it’s attracting bozos. Plenty of solid recommendations above
