Verify your brand domain

Prove you own your brand domain with a DNS record or a text file, declare what you advertise, and control how you appear to publishers.

Publishers decide who may advertise on their channels by brand domain and by category. Verifying your domain proves who you are. Declaring your categories lets publishers apply their own rules fairly.

Why verify

  • Until your domain is verified, LtvAdx sends no advertiser domain with your ads and lists you as confidential.
  • Once verified, your domain goes out as the advertiser on your ads, and you can appear by name in the public list of buyers.
  • Publishers match their blocks against your domain, verified or declared, so a block applies either way.

Before you start

You need to be able to add a DNS record to your domain, or place a text file at the root of its website. Only owners, admins and managers on your account can change brand settings.

Steps

  1. Open Brand verification.
  2. Enter your brand's website domain, for example acme.com, and select Save domain. Use a domain your business owns: a shared platform address is refused.
  3. Choose one proof. Either add the TXT record shown on the page to your domain's DNS, or publish the text file shown at the web address on the page, containing the token.
  4. Select Check now. LtvAdx looks for the record first, then the file.
  5. Under What you advertise, enter the IAB category codes for your products, such as IAB13, and select Save.

What happens next

The status badge reads Verified when a check finds your proof. LtvAdx re-checks verified domains every week. If the proof has gone, the status reads Failed and your domain is withdrawn from your ads until you restore it. A check that cannot get an answer at all, for example a DNS timeout, does not remove a verification.

StatusMeaning
No brand domain yetNothing entered.
Not verified yetWaiting for a proof.
VerifiedProven by DNS record, text file, or by LtvAdx after reviewing your documents.
FailedIt was verified, and the record is gone.

Changing the domain withdraws verification and issues a new token.

Categories

Enter up to 10 IAB codes. A code like IAB7 covers its sub-codes. Publishers block categories they do not carry, and a blocked category keeps your ads off their channels. Declare yours honestly: a wrong category can get your ads removed.

Public buyer list

Your buyer ID appears in the public list of buyers when your account is live and active. Untick Show my name and verified domain in buyers.json to be listed as confidential instead.

If something goes wrong

  • Enter your brand's website domain, e.g. acme.com. The value was not a domain.
  • No TXT record on your domain, or no verification file at the root of the domain. The proof is not published yet, or DNS has not caught up. Wait and select Check now again. Checks are limited to one a minute.
  • Checks are not switched on yet. LtvAdx can verify you by hand. Contact support with evidence that you own the brand.
  • Your seat cannot change brand verification. Ask an owner, admin or manager.
  • A publisher blocks you after verification: see Choose publishers and channels and the ad and content policy.
