X Analytics Tool That Shapes Your Next Posts
GrowX is an X analytics tool built for one job: showing which of your posts work and writing more like them. It tracks engagement by day, by topic, by format, by posting hour and with or without an image over the last 30 days, and the writer uses the same numbers to shape your next drafts.
What the X analytics tool shows
| View | What you learn |
|---|---|
| Engagement per day | Whether the last 30 days are trending up |
| Average engagement by topic | Which of your content pillars your audience cares about |
| Average engagement by format | Whether lists, stories, how-tos or takes do best for you |
| Engagement by posting hour | When your audience responds |
| With and without an image | Whether images earn their place on your posts |
Engagement here means likes, replies and reposts on your own posts.
How it works, step by step
- Post through GrowX or on X as usual. Your posts are matched to your account.
- Numbers arrive two ways. The Chrome extension reads the figures on screen when you open your own posts or X's analytics page, at no cost. You can also switch on a nightly read of your last 7 days of posts through the X API.
- Open Analytics in the web app to see the 30-day views.
- The writer learns. Your best posts weigh more as examples when GrowX drafts the next ones, so the queue drifts toward what works.
Who it is for
- Builders and creators who want to know what to post more of, without a spreadsheet.
- Anyone posting on a cadence who wants each week to beat the last.
- People who want a short dashboard that answers one question: what to post next.
Limits on the plan
Analytics is included in Pro at $15 a month and in the lifetime licence ($39 to $99 once). The extension path is free and always on. The nightly API read is opt-in and covers your posts from the last 7 days. See pricing.
Frequently asked questions
Does GrowX show follower growth?
GrowX analytics focuses on engagement per post: by day, topic, format, hour and image use. For changes in who follows you, see our guide on how to see who unfollowed you on X.
How is this different from X's own analytics?
X shows numbers per post. GrowX groups them by the choices you make, such as topic, format and hour, and feeds the result into your next drafts.
Do I need the Chrome extension?
It is the free path for numbers. Without it, switch on the nightly API read in settings.
How do I work out my engagement rate?
Divide engagements by impressions and multiply by 100. The free engagement calculator does it for you.
What counts as a good engagement rate on X?
It depends on account size and niche, so compare against your own last 30 days first. Our guide on how to grow on X covers a weekly review routine.
