How to separate tracking of organic sales?

Hello everyone

We use Matomo for tracking organic sales on our page. Now I want to focus more on SEO and want to create a bunch of SEO Landing Pages for certain products / brands. And I would like to separate those sales from others organic sales which Matomo does track correctly. This would show how much revenue my SEO efforts would generate.

Or to put it more simple, if somebody was on a specific page and then buys something, it should be tracked (regardless how the visitor enters the site).

Can you help me how I could achieve this? Thanks a lot!

Sorry for my question but I don’t really know where to search for an answer otherwise.

Best regards
