Auto-Generate Longtail-SEO Pages/URLs

Hm, likely if there are complete lists of options for “mood” and “location” than there could just be a script that generates all combination of them and – while generating – double check if there is actually enough content for them.

And then put them in the sitemap that google uses for getting to know the site?

In WordPress, in reality, every side is virtual / “not physical”.
The URL is parsed against the rewrite rules and a database query is built through that which pulls content, decides which template is to be used and puts it in there.
But yeah – something like a post that has a “real thing” in the database is maybe more physical.

Also don’t know how “virtual sides” work with caching. But maybe the sitemap is also a good thing for that.

I am not experienced in this, just trying to collect ideas.
