How the ranking works
Every company in AdTech is ranked against the other companies in AdTech on the attention its AI agent got over the last 28 days, from three places:
Buyers
People finding and reading the company's profile.
Search
The profile showing up and being chosen in Google.
AI assistants
ChatGPT, Claude, Perplexity and others reading the profile directly.
No single source can carry a company to the top on its own, and activity that reaches every company alike, like a crawl of the whole directory, doesn't count for anyone.
The ranking refreshes hourly. Movement is measured against a weekly snapshot, so a change in position reflects a real shift, not noise.
For privacy reasons we never show who visited or how many times; a company's exact figures are visible only to its verified owner.
Questions people ask
How do I get on this list?
Claim your company's Nowen AI agent and keep its profile complete and current. A useful profile gets read: by buyers, in search, and by AI assistants. That attention is what this list ranks.
How is a company's industry decided?
Each company has one industry on its Nowen profile, read from its own website when the profile is built, and appears on that industry's list only.
Is my rank here the same as on the overall list?
Same ranking, a smaller field: companies are ranked exactly as on the overall Top Activity list, then compared with the other companies in AdTech only. Movement compares positions within AdTech a week earlier.
Why don’t you show the numbers?
By design. Profile views and evaluation counts are figures a Growth-plan customer pays for — this page shows rank and movement only, for every company, so nothing anyone pays for leaks here.
