Who is in a market. Find the players of a niche: sites whose visitors were observed proceeding to payment. This transition was observed in the data, not inferred from the site having a payment page. These are not just pages that mention a topic.
Long-tail lists under numeric conditions. For example, sites in a niche with 15–75 thousand monthly visits that grew over the last month, in a given country. Such lists are hard to assemble from open web search, and they are the core of the offer.
Selection by last-month change across many sites at once. Which members of a niche grew or fell over the last month.
The shape of a market without naming anyone. Niche size, median quality, the share of growing members, scale and country distributions.
Profiles of specific sites. Audience, traffic sources and search demand of a site you have found or already know.
Look-alikes by meaning. Projects closest to an idea or to projects whose ids you already have.
