    So nutzt du: ads.txt Generator
    1. Add a record for each ad network — pick a preset or enter the ad system domain manually.
    2. Enter your publisher account ID exactly as your ad network shows it (for AdSense: pub- followed by 16 digits).
    3. Choose DIRECT if you have the account yourself, RESELLER if a partner sells on your behalf.
    4. Download and upload ads.txt to the root of your domain.
    

    What is ads.txt?
    

    ads.txt (Authorized Digital Sellers) is an IAB Tech Lab standard that lets website owners publicly declare which companies may sell their ad inventory. Advertisers’ platforms check the file before buying, which cuts off domain spoofing and fraudulent resellers. Google AdSense warns you in its dashboard when your ads.txt is missing or incomplete, and missing records can reduce your ad revenue.
    

    Record format
    

    google.com, pub-0000000000000000, DIRECT, f08c47fec0942fa0
    

      

    1. Ad system domain — the network’s canonical domain (google.com for AdSense and Ad Manager).
      2. 

    2. Publisher account ID — your ID in that system.
      3. 

    3. Relationship — DIRECT (you control the account) or RESELLER (an intermediary sells your inventory).
      4. 

    4. Certification authority ID (optional) — the network’s TAG ID; Google’s is f08c47fec0942fa0.
      5. 

    

    Variables
    

    contact= gives a contact for the file; OWNERDOMAIN= and MANAGERDOMAIN= (ads.txt 1.1) identify the business that owns the site and any manager that handles its inventory.
    

    Uploading and checking
    

    The file must be at the root of the domain — https://example.com/ads.txt — and return HTTP 200 as plain text. Crawlers may take a few days to pick up changes. Mobile and CTV apps use the same format in an app-ads.txt file on the developer’s website.

    Häufige Fragen
    Where do I find my AdSense publisher ID?
    In AdSense under Account → Settings → Account information. It looks like pub-1234567890123456.
    Is ads.txt required?
    It’s not legally required, but Google and most ad exchanges strongly recommend it, and unauthorized inventory may receive fewer bids.
    How long until AdSense detects my ads.txt?
    Usually within a few days, sometimes longer for low-traffic sites. Make sure the file returns HTTP 200 at the domain root.
    What is the difference between DIRECT and RESELLER?
    DIRECT means you own and control the ad account. RESELLER means another company is authorized to sell your inventory through their account.
    Kann ich ads.txt Generator als Web-App installieren und offline nutzen?
    Ja. ads.txt Generator ist eine installierbare Web-App (PWA) – sie wird über Ihren Browser installiert und nicht aus einem App-Store heruntergeladen. Klicken Sie oben auf dieser Seite in Chrome oder Edge (Windows, macOS, Linux, ChromeOS) auf „App installieren“ oder verwenden Sie auf Android-Geräten „Teilen“ → „Zum Startbildschirm hinzufügen“ auf dem iPhone und iPad bzw. „Datei“ → „Zum Dock hinzufügen“ in Safari 17+ auf einem Mac. Die App öffnet sich dann in einem eigenen Fenster mit einem eigenen Symbol, und da sie vollständig in Ihrem Browser ausgeführt wird, funktioniert sie auch offline. Firefox auf dem Desktop kann keine Web-Apps installieren. So funktioniert die Installation.
