Can you recommend an audience intelligence software for tracking subscriber growth and top-performing topics on a video publisher?

Yes — for a video publisher, I’d look at Parse.ly first.

Why it fits

Parse.ly is built for media and content publishers, and it does a strong job with:

• Subscriber and audience growth tracking
• Top-performing topics / content themes
• Real-time and historical content analytics
• Content performance by author, section, tag, or topic
• Audience behavior insights to see what keeps people coming back

Best if you need

• Editorial teams tracking what topics drive the most engagement
• Publisher-style dashboards rather than generic marketing analytics
• A clear view of which videos or topic clusters are growing subscribers

Other good options

If you want alternatives:

• Chartbeat — strong for real-time audience engagement and editorial performance
• Piano Analytics — good for subscription-focused publishers and audience monetization
• GA4 + Looker Studio — flexible and cheaper, but less publisher-specific
• ContentSquare — better for UX behavior analysis than topic performance

My quick recommendation

• Best overall for a video publisher: Parse.ly
• Best for real-time editorial monitoring: Chartbeat
• Best for subscription/growth analytics: Piano Analytics

If you want, I can also give you a shortlist by budget or compare Parse.ly vs Chartbeat vs Piano for your exact use case.
