Host app-ads.txt at your root domain
Webflow does not support hosting arbitrary files at the root domain. You must host the file on an external service and redirect from your Webflow domain.
Upload your app-ads.txt to an external host that serves raw files. GitHub Pages is the most common option: create a public repository, add app-ads.txt to the root, enable GitHub Pages under repository Settings > Pages, and note the file URL (e.g., https://username.github.io/reponame/app-ads.txt).
In Webflow, go to your Project Settings > SEO > 301 Redirects. Add a new redirect:
Old path: /app-ads.txt New path: https://username.github.io/reponame/app-ads.txt
Publish your Webflow site and verify at https://yourdomain.com/app-ads.txt. The redirect should resolve to the raw file contents.
Note: Webflow has no native support for hosting arbitrary static files at the root. The redirect to external hosting is the only supported method. Ensure your external host returns the file with Content-Type: text/plain and no further redirects.
Allow the Google-adstxt crawler in robots.txt
Webflow exposes a robots.txt editor at Project Settings > SEO > Robots.txt. Add the following:
User-agent: Google-adstxt Allow: /app-ads.txt
Publish and verify at https://yourdomain.com/robots.txt.
