Well, it wouldn&#x27;t be the target for your small personal blog... once you approach it at a small business level, it means running server-side code do deliver ads injected into your content that reports what data can be reported upstream.<p>It does mean more limited analytical data, but it would also mean better privacy constraints... it means moving the delivery to first-party servers, that can use other SaaS behind that.<p>As to advertizing, it means delivering an image url, and a target url... no more leaps and bounds of JS, or for that matter layers of iframes..<p>TBH though, if browser vendors simply disabled JS, and iframes more than 3 layers in, and limit JS files to 3 max (100kb size limit) within an iframe, the advertizers would probably successfully self-correct..
