Hello everyone,
You can find a form to insert advertising on the portal of google?

thank you very much

If I understand you correct, I would do it like this.

Create a HTML or php ( or whatever file you want ) file, and add the google code for adverts you want to have into this file... and then upload that to your website.
Create a custom block on your portal and add in the portal custom code block, an iframe with the url of your new file.

Im still not quite sure what sort of advertising you want to put in, or how that would work, but I assume they provide you with the code.
