If you are running display ads on your website using Google AdSense, GAM, SSPs, or programmatic advertising, then having a clean and optimized ads.txt file is extremely important.

🔍 What Is Ads.txt and Why It Matters?
Ads.txt (Authorized Digital Sellers) is an IAB Tech Lab initiative that allows publishers to declare who is authorized to sell their ad inventory.
An ads.txt file:
- Prevents ad fraud
- Protects your inventory from unauthorized sellers
- Helps advertisers trust your website
- Improves programmatic ad efficiency
However, if your ads.txt file contains duplicate or conflicting entries, it can do more harm than good.
❌ How Duplicate Ads.txt Entries Hurt Your Website
Many publishers don’t realize that duplicate ads.txt lines can cause serious issues, such as:
- ❌ Rejected bids from SSPs
- ❌ Slower ads.txt crawling by Google
- ❌ Confusion between DIRECT and RESELLER entries
- ❌ Lower CPMs and fill rates
- ❌ Poor ads.txt crawl status in Google Ad Manager
Even if the duplicates look harmless, ad platforms treat them as technical errors.
