About AdTech Sumo

AdTech Sumo explains advertising technology to everyone: the marketer who just heard the word “programmatic”, the publisher wondering where their revenue went, the investor reading an earnings call, and the engineer building the next bidder. The name comes from the sumo ring, the dohyo in our logo, where two contenders face off at the starting lines. Every ad impression is a contest like that, decided in a tenth of a second.

Who is behind it

AdTech Sumo is published by ClearTrust, a company that builds solutions to prevent ad fraud and invalid traffic, including the Traffic Quality Index (TQI) Score™. ClearTrust sponsors the site and its house ads appear in ad slots when no other advertiser has bought them. Its products are listed in the players directory alongside competitors, with the same format and no ranking advantage in the news.

How we gather information

The desk reads 34 sources continuously: trade publications, industry bodies, and Google News searches for ad tech, fraud, deals, earnings and regional coverage in North America, Europe, India, Asia-Pacific, Latin America and the Middle East and Africa. It has gathered 460 stories so far. Stock quotes come from Nasdaq and Yahoo Finance and are delayed. Company filings, earnings releases and quarterly figures come directly from the SEC’s EDGAR system.

How we write

• Every story is summarised in our own words, with a “why it matters” line for non-experts, and always links to the original report. We never republish articles.
• Summaries are drafted by a language model from the outlet’s headline and excerpt, under strict rules: no facts, numbers or quotes that are not in the source. When no model is available, we show the outlet’s own short summary and say so.
• Earnings explainers use only figures in the company’s SEC-filed press release.
• Lessons, glossary entries and answers are written and fact-checked against primary sources: IAB and IAB Tech Lab specifications, MRC guidelines, TAG, regulators and court documents. Estimates are always attributed.
