Where to place ads in the extension?

Question

Monetization

There is an extension for the browser - online radio. After launch, a window appears at the bottom of the page, in which the radio is located. I also plan to place ads in this window.
I would also like to embed ads in the web page itself. How to do it better? The first option - at the bottom of the page, a welcome window for the extension will appear, in which there will be a description of the extension, as well as an advertising banner. This window can be closed and will no longer be shown until the browser is opened again. The second option is to place an advertising banner in any free space on the page.
I want to do this with the goal that ads are always shown, and not just when the user uses the extension. This will greatly increase your views.

Answer 1

I would also like to embed ads in the web page itself.

Now that's overkill. In extreme cases, you can replace the ads that are already on the page with your own.

Answer 2

As Taraflex noted, this is really overkill. And even if you want to deal with bypassing the extension policy, you will have to connect a proxy server to intercept pages loaded by users. And it's not even the most painful place. Browser updates are starting to include a built-in ad blocker:
