How to Add Contact Us Page in Blogger (Step-by-Step Guide for Beginners)

In this post, I’ll explain what app-ads.txt is, why it matters, and show you step by step how to add it to your Blogger site in just a few minutes.
app-ads.txt is a simple text file that lists all the advertising networks and resellers that are officially allowed to sell ads for your app.
It is the apps version of the ads.txt standard used by websites.
Prevents fraud: Blocks unauthorized sellers from pretending to sell your app traffic.
Improves revenue: Buyers trust your inventory and bid higher, increasing eCPM.
Required by networks: AdMob and many others now expect it for proper verification.
Here are some sample lines you might add:
google.com, pub-9115076398426079, DIRECT, f08c47fec0942fa0
applovin.com, 6aeced8521f9d0e07517fc12042ece35, DIRECT
unity.com, 7369187, DIRECT, 96cabb5fbdde37a7
Each line tells advertisers:
The ad network domain (e.g., google.com)
Your publisher/account ID
The type (DIRECT or RESELLER)
An optional certification ID
Log in to Blogger Dashboard and open your blog.
From the left menu, click Settings.
