Blogger Ads.txt Not Found Fix: AdSense Warning Solution After Adding Code
A complete step-by-step guide to fix Blogger ads.txt not found issue after adding code, custom ads.txt errors, AdSense warning and publisher ID problems.
If you added ads.txt code in Blogger but AdSense is still showing ads.txt not found, then do not panic. This issue is very common for new Blogger users, Blogspot users and custom domain Blogger websites. Many times the code is correct, but AdSense takes time to detect it.
Sometimes the problem happens because the custom ads.txt option is not enabled, sometimes the wrong publisher ID is pasted, sometimes the domain version is different, and sometimes AdSense simply has not updated the status yet.
In this guide, I will explain Blogger ads.txt not found fix, why the warning appears after adding code, how to check your ads.txt file, where to paste ads.txt in Blogger, and what you should do if AdSense still shows the warning.
What Is Ads.txt in Blogger?
Ads.txt means Authorized Digital Sellers. In simple words, it tells advertisers which ad networks are allowed to sell ads on your website. For AdSense users, it normally contains your Google AdSense publisher ID.
Simple meaning: Ads.txt helps AdSense and advertisers confirm that your website is authorized to show ads through your publisher account.

Why Ads.txt Shows Not Found After Adding Code?
If you already added code but AdSense still says not found, there can be multiple reasons. First understand the reason, then apply the fix.
| Reason | What It Means | Quick Fix |
|---|---|---|
| AdSense status delay | AdSense has not rechecked your file yet | Wait and check updates |
| Wrong publisher ID | Your pub ID is missing or incorrect | Copy code from AdSense only |
| Custom ads.txt disabled | Blogger is not publishing your ads.txt | Enable custom ads.txt in settings |
| Wrong domain version | AdSense checks different domain version | Check www/non-www setup |
| Cache or propagation delay | Browser or AdSense has old status | Open /ads.txt and wait |
| Line format mistake | Extra text, wrong comma or wrong spacing | Use exact format |
Step-by-Step Fix: Blogger Ads.txt Not Found
Now follow these steps carefully. Do not change everything again and again. First check the basic setup.
Open AdSense
Login to AdSense and copy your real ads.txt line from your account.
Open Blogger Settings
Login to Blogger and select the blog where you want to fix ads.txt.
Find Monetization
Scroll down in Settings and find Monetization section.
Enable Custom Ads.txt
Turn on custom ads.txt if it is disabled.

Paste your real AdSense ads.txt line without extra text.

Where to Add Ads.txt Code in Blogger?
You do not need to edit Blogger theme HTML for ads.txt. Blogger gives a separate setting for this.
- Open Blogger Dashboard.
- Go to Settings.
- Scroll down to Monetization.
- Enable Custom ads.txt.
- Click on Custom ads.txt.
- Paste your AdSense ads.txt line.
- Click Save.
How to Check If Ads.txt Is Working?
After saving the code in Blogger, you should check the live ads.txt file manually.
Open this in browser: https://www.yourdomain.com/ads.txt
For Blogspot: https://yourblog.blogspot.com/ads.txt
If you can see your ads.txt line in browser, then the file is published. If it shows 404, blank page or old code, then something is still wrong in Blogger settings or domain setup.
Ads.txt Opens in Browser But AdSense Still Says Not Found
This is very common. If your /ads.txt URL opens correctly in the browser but AdSense still shows not found, then mostly the issue is status update delay.
Do this:
- Do not delete the code again and again.
- Do not change the publisher ID randomly.
- Open AdSense and check the Sites section.
- Use the check/update option if available.
- Wait for AdSense to refresh the status.
Check WWW and Non-WWW Domain Version
If you use a custom domain in Blogger, domain version matters. Sometimes your website opens with www, but AdSense may check the non-www version, or the redirect is not working properly.
| Check | Example | What Should Happen |
|---|---|---|
| WWW ads.txt | https://www.example.com/ads.txt | Should show your ads.txt line |
| Non-WWW ads.txt | https://example.com/ads.txt | Should redirect or show same file |
| HTTP version | http://example.com/ads.txt | Should redirect to HTTPS |
| Blogspot version | yourblog.blogspot.com/ads.txt | Should match your setup if still used |
Common Mistakes While Adding Ads.txt in Blogger
Most ads.txt not found errors happen because of small mistakes. Avoid these mistakes if you want a clean setup.
| Mistake | Problem | Correct Fix |
|---|---|---|
| Using sample pub ID | AdSense cannot verify your account | Use your real publisher ID |
| Pasting HTML code | Ads.txt format becomes wrong | Paste only one ads.txt line |
| Custom ads.txt disabled | Blogger does not publish the file | Enable custom ads.txt |
| Wrong comma format | File may not be verified | Use exact AdSense format |
| Checking too early | Status still shows not found | Wait for AdSense update |
| Wrong domain version | AdSense checks another URL | Fix www/non-www redirect |
How Long Does Ads.txt Take to Update in AdSense?
There is no fixed instant time. Sometimes AdSense detects ads.txt quickly, sometimes it can take a few days. If your website has low traffic or low ad requests, it may take longer.
Keep checking your AdSense Sites section, but do not panic if the warning does not disappear immediately.

Final Conclusion
Blogger Ads.txt Not Found after adding code is usually not a big issue if your code is correct and visible at /ads.txt. The main thing is to check your publisher ID, enable custom ads.txt, use the correct domain version, and wait for AdSense to refresh the status.
Do not keep changing the code again and again. First open your live ads.txt URL in browser. If the line is visible there, your Blogger side setup is mostly complete. After that, give AdSense some time to update.
Keep your Blogger monetization setup clean, use your real AdSense publisher ID, and avoid copied code from random websites.
