ads.txt Setup Guide

Step-by-step guide to uploading your personalised ads.txt to your domain root — for standard servers, WordPress, and hosted builders — plus how to merge with an existing file.

Your ads.txt file is a plain text file hosted at the root of your domain that authorises Advlume and its demand partners to sell your advertising inventory. Setting it up correctly is one of the most important steps for maximising your fill rate and CPMs.

Getting your personalised ads.txt

Log in to the Advlume dashboard.
Open your site: Dashboard → [site name] → Settings → ads.txt.
Copy the full contents of your personalised ads.txt file, or click Download.

Your file is personalised — it includes your specific seller ID in the Advlume reseller line. Do not use another publisher's file or a generic template.

Uploading the file

The file must be accessible at https://yourdomain.com/ads.txt — exactly at the root, not in a subfolder.

Standard web server

Create a plain text file named ads.txt.
Paste the contents from the dashboard.
Upload the file to the root directory of your web server (the same directory that serves your homepage).
Verify it is accessible at https://yourdomain.com/ads.txt in a browser.

WordPress

Upload the ads.txt file to the root of your WordPress installation (the directory containing wp-config.php), not to /wp-content/.
Alternatively, use the Ads.txt Manager plugin to manage the file from the WordPress admin panel.

Webflow / Squarespace / Wix

Most hosted website builders have a dedicated field for ads.txt content in their SEO or publishing settings. Check your platform's documentation for "ads.txt". If no dedicated field exists, contact your platform's support — some platforms do not allow custom root files.

Verifying the setup

After uploading:

Visit https://yourdomain.com/ads.txt in a browser and confirm the file loads correctly and contains your Advlume lines.
In the Advlume dashboard, click Check ads.txt (if available) to confirm the file is reachable.
In Google Ad Manager, check Admin → Ads.txt — any warnings should resolve within 24 hours of uploading a valid file.

Keeping it up to date

Advlume's demand partner list evolves. When new bidders are added, your ads.txt needs new lines. The dashboard will flag your file as outdated when this happens. Check Settings → ads.txt periodically and re-upload the latest version.

You do not need to re-verify your domain after updating the file — simply replace the existing file at your domain root.

If you already have an ads.txt file

If your domain already has an ads.txt file for another ad network, do not replace it — merge the Advlume lines into your existing file. Keep all existing lines and add the Advlume-specific entries below them. Both Advlume and your existing network's entries can coexist in the same file.
