Frequently Asked Questions
What subreddits does this tool analyze?
We analyze posts from r/popular (Reddit's hot feed) plus targeted tech and business subreddits like r/technology, r/business, r/startups, r/SaaS, r/programming, and r/webdev. This gives a broad view of what's trending across Reddit with a focus on professional and tech communities.
How are trending topics identified?
We extract keywords from post titles, filter out common stop words, and require at least 3 occurrences across the analyzed posts. Topics that appear in multiple subreddits are ranked higher, as cross-subreddit trends indicate broader interest.
How often is the trending data updated?
Trending data is cached for 2 hours to stay relatively fresh while maintaining performance. Each analysis pulls the latest hot posts from Reddit.
How many posts are analyzed?
We analyze up to 300+ posts from the popular feed and multiple subreddits. The exact count depends on Reddit's API response at the time of the request.
