Great! Only one request.
I'm guessing that changing this may be difficult, but it would be nice to not have "advertisement" and "ad_click" in the URL.
Other than that, great!
You might be able to get what you want by overriding the existing block and tool in the add-on. I think this might require a good deal of editing php files so if that's not something you're comfortable with you might need to hire someone to make the changes for you.
This will basically give you a new block on your site that is now disconnected from the advertisement add-on's update path, but that add-on is basically at feature freeze so it should not have a new version.
Here is a how-to on overrides:
This might require a decent amount of customization to do because if you want to change the block's name in the url from "advertisement", you'll need to change any place where the block's handle is referenced as "advertisement" in code to whatever you named it.
Simple and integrated
Still great product
