Verification and integration.
WHAT ASKS FOR THEM
Search Console Business profile verification Email sending services Payment gateways Collaboration platforms Security and monitoring services
WHAT THEY ASK FOR
Usually a TXT record with a specific value, or a CNAME pointing at their hostname.
WHERE TO ADD IT
Wherever your DNS actually lives. If your nameservers point at Cloudflare, there. Not cPanel.
This is the most common reason verification fails repeatedly for no apparent reason.
ENTERING THE VALUE
Exactly as given. These values are frequently long strings and a single altered character fails.
Copy and paste rather than typing.
THE NAME FIELD
Some services want the record at the bare domain, some at a specific subdomain such as _verification.
Read carefully. Adding it at the wrong name fails silently.
AFTER ADDING
Most services check within minutes. At Cloudflare, changes take effect almost immediately.
Elsewhere, allow for the TTL.
KEEPING THEM
Do not remove verification records after verifying. Many services re-check periodically and verification lapses if the record is gone.
