Sellers Report – February 2025

Ads.txt Lines:

In January 2025, the addition of 69,177 new ads.txt lines and the removal of 65,478 existing lines resulted in a net change of approximately +3.7K lines. This positive net change is inline with last year’s trend where we have seen a net change of around +6K lines in Jan 2024.

The provided snapshot illustrates the distribution of line changes among different tiers of publishers. While looking in-depth, it appears that Tier-1 SSPs shows a good positive net change in ads.txt lines, with an increase of approximately 2,500+ lines, which looks great.

Auction Duplication: A Critical Issue in the AdTech Industry

• Tier 1 SSPs are expected to have a lower share of Direct Only Domains and a higher share of Direct + Reseller Domains in comparison to other tiers. This is attributed because Tier-2 and Tier-3 SSPs rely on Tier-1 to serve as a demand partner.
• However, during this process, Tier 1 SSPs may inadvertently be listed as a reseller on domains where they are already directly connected, leading to auction duplication and classification as Direct + Reseller Domains.
• For SSPs, especially Tier 1, managing intermediaries in choosing non-duplicate domains is challenging. Additionally, it becomes an added responsibility for SSPs to address both auction duplication and carbon emissions. Choosing the right intermediary is crucial for reaching unique domains where their ads.txt lines are not yet present.

At DataBeat, we offer assistance in identifying and managing ineffective intermediaries, reducing duplicate domains, and improving your green index score while not compromising on your net revenue. Leveraging our Competitive Intelligence (CI) Tool, we enable you to identify & address these challenges effectively.

Breakdown of domain connections to SSPs by relationship types (Direct Only, Reseller Only, Direct + Reseller)

• Direct Only: Domains exclusively connected through direct relationships.
• Reseller Only: Domains exclusively connected through reseller relationships.
• Direct + Reseller: Domains with both direct and reseller connection

Proportion of unique and duplicate domains, and average number of intermediaries influence on duplicates.

• Unique Domains: Domains exclusively connected to an SSP through a single connection.
• Duplicated Domains:  Domains connected to an SSP through multiple intermediaries or integrations, resulting in duplications.
