  "country": "US",
  "title": "How Google Ads Detect Which Web Page You Are Viewing",
  "original_title": "Serving advertisements based on content",
  "summary": "A method for web browsers to identify the correct webpage address to show relevant advertisements, even when the ad code is hidden inside a frame.",
  "what_it_does": "This patent describes a way for an ad-serving system to figure out exactly which webpage a user is looking at so it can show relevant ads. When a website loads, it often includes small pieces of code (like JavaScript) that fetch ads. The problem is that these ads might be inside a sub-window called a frame, which can confuse the ad server about the actual page URL. This patent claims a method where the browser runs a comparison check: it looks at the location of the ad code and compares it to the main page URL. If they match, it uses that address; if they don't match or are blocked by security rules, it falls back to the 'referrer' link to find the true page address.",
  "what_it_does_not_cover": [
    "Does not cover the actual logic used to select which specific ad to display based on the page content.",
    "Does not cover methods of tracking user behavior across different websites or domains.",
    "Does not cover server-side ad insertion where the ad is baked into the HTML before the page reaches the browser.",
    "Does not cover non-browser applications that do not use URL-based document identifiers."
