Trends across marketplaces
What people want, whatever marketplace it shows up on. A topic is a need, such as LinkedIn tools or email verification, followed across every marketplace that serves it.
No topic can be ranked yet. A topic needs a week of history on at least two marketplaces.
How marketplaces are put together
Every marketplace labels its listings its own way. One has categories, another tags, another nothing at all, and the same need goes by different names. So their lists cannot simply be added up.
- Read. Each marketplace's tags, and the words in listing names, are put in one spelling.
- Merge. A curated list says which of them mean the same need. A language model judges the common ones the list does not cover: an existing topic, a new one, or too vague to mean anything.
- Rank. A topic is scored by where its growth stands among the topics of each marketplace, then averaged. Counts from different marketplaces are never added together.
A growth score of 80 means the topic outgrew 80% of topics, on average, on the marketplaces that have it. The full definitions.
