Free Blogger Ads.txt Generator — why it matters for AdSense approval
If you run a Technology & AI blog (tutorials, model reviews, or AI tool roundups), a single line in an ads.txt file can be the difference between AdSense approval and being rejected — or losing ad revenue. This guide shows the exact steps, examples, and fixes for common AdSense rejected reasons.
Step 1 — Understand what ads.txt does
Ads.txt (Authorized Digital Sellers) tells advertisers which companies are authorized to sell ads for your domain. For AdSense, Google requires a valid ads.txt entry to verify your publisher ID and prevent unauthorized resellers.
Tech & AI blogger example
Example: you run "ai-gadgets.example" reviewing AI hardware. If you omit or mis-format your ads.txt, AdSense may flag the site during verification and show "ads.txt missing" or even reject the application.
Step 2 — Get your AdSense Publisher ID
Where to find your Publisher ID
- Sign in to your Google AdSense account.
- Open Account → Settings → Account information.
- Copy the Publisher ID in the format:
pub-XXXXXXXXXXXXXXX.
Example: If your AdSense account shows pub-XXXXXXXXXXXXXXX, that's the exact text you must use in your ads.txt line.
Step 3 — Generate the correct ads.txt line (fast)
Use the embedded generator below to produce the exact line required by AdSense:
Rekreay — Free Blogger Ads.txt Generator
This tool builds the required ads.txt entry for Google AdSense. Paste the generated line into Blogger's custom ads.txt area to avoid approval delays.
Publisher ID reminder
- Open AdSense and copy
pub-XXXXXXXXXXXXXXX. - If you paste only numbers, the generator auto-adds the
pub-prefix.
How to Use This Code
- Go to your Blogger Dashboard.
- Navigate to Settings → Monetization.
- Enable the toggle for "Enable custom ads.txt".
- Click on "Custom ads.txt" (the text, not the toggle).
- Paste the generated code from the box above and click Save.
Step 4 — Validate the ads.txt entry
After pasting, verify the line looks exactly like:
google.com, pub-1234567890123456, DIRECT, f08c47fec0942fa0
Replace pub-1234567890123456 with your publisher ID. If the pub- prefix or checksum is missing, Google will flag the file.
Step 5 — Typical AdSense rejected causes & fixes (for Tech & AI bloggers)
Below are the most common reasons AdSense rejects or delays approval and how to fix them.
1. Missing or malformed ads.txt
Fix: Use this generator and paste the exact single-line entry. Confirm no extra characters or markup are present — only plain text.
2. Wrong Publisher ID
Fix: Copy the ID from AdSense → Account information. Example: AI model review site uses pub-9876543210123456. Double-check digits.
3. Ads.txt not visible to crawlers
Fix: After saving, visit https://yourblog.blogspot.com/ads.txt (or your custom domain) to confirm the file is publicly accessible.
4. Multiple entries or typos
Fix: Only include Google’s recommended lines for AdSense. Remove duplicated or unrelated vendor entries until approved.
Practical examples for Technology & AI blogs
Example A — AI tools review blog
Site: ai-tool-lab.example — After generating and pasting:
google.com, pub-9876543210123456, DIRECT, f08c47fec0942fa0
Example B — ML tutorial blog that uses a custom domain
If hosted at ml-hub.example, confirm the file at https://ml-hub.example/ads.txt. Use the generator, paste, then visit the URL to confirm visibility.

Frequently Asked Questions
Will a missing ads.txt cause AdSense to reject my application?
Possibly — Google may delay or flag your application. While missing ads.txt alone is not always the only reason, it's a required step for many publishers. Fixing it removes one common rejection cause.
Can I add multiple publisher IDs in one ads.txt?
Yes — you can list multiple valid seller lines. During initial approval, keep it simple and include only your primary AdSense line to avoid confusion.
How long after adding ads.txt will AdSense update?
Typically, crawlers pick up the file within 24–72 hours. If you still see issues after 72 hours, re-check the file for typos and confirm the URL is publicly accessible.
My ads.txt shows extra HTML or tags — will that fail?
Yes — ads.txt must be plain text with each entry on its own line. Remove any HTML, BOM markers, or editor metadata before saving.
Troubleshooting checklist (quick)
- Use the Rekreay generator to produce the line.
- Paste exactly one Google line into Blogger custom ads.txt.
- Visit
https://yourdomain.com/ads.txtand confirm the line is visible. - Wait 24–72 hours for AdSense to re-crawl; check AdSense account for errors.
