But this brings up a good point. What is the value of google showing you the play buttons in the search results? They're trying to keep you on google's site.
But why? I don't see a financial motivator here, unless there is some long-game that I'm not aware of. In theory, driving users to websites in a search result is likely just going to make Google more money from displaying ads.
The only thing I can currently think of is they actually are trying to improve the user experience.
This is the company that decides shades of blue by conversion numbers.
Maybe they indirectly want to 'improve user experience' (so you're less likely to leave) but it's not their terminal value.
Why would it be more profitable to send users to the BBC website?
If you listen via Google they not only know what you listened to but for how long you listened, which parts you skipped over or stopped listening at, and whether you listened to the ads or not. All that information has value to them. Being able to say these people googled your product within 72 hours of hearing your ad on these podcasts is very valuable.

Wouldn't anyone prefer #2? Including the BBC's programme makers?
