Reach is not audience size
Reach counts the unique accounts that actually saw a post. It is routinely a small fraction of follower count, and the gap between the two is the single most useful diagnostic available.
When reach falls while followers grow, distribution is being throttled because the audience is not responding. Fixing that requires attention to engagement, not to acquiring more followers.
How distribution decisions are made
The general pattern is consistent across platforms. A post is shown to a limited slice of the potential audience, the response is measured, and further distribution depends on that response.
Early engagement therefore acts as a gate. This explains why the first hour matters, and why posting when your audience is active has an effect out of proportion to the effort involved.
What reliably increases reach
The effective changes are mostly about clarity and consistency rather than tactics.
- Keep a narrow topic so the system can identify the right audience to test.
- Prioritise formats the platform is currently distributing widely, which is usually short video.
- Publish on a predictable schedule to create repeated opportunities for discovery.
- Optimise the opening seconds or first line, where most drop-off occurs.
- Reply to comments quickly to strengthen the early signal.
- Cut formats that consistently underperform rather than persisting with them.
What tends not to work
Hashtag volume has limited effect on most platforms now, and posting more often across unrelated topics usually reduces performance rather than improving it.
Inflating follower counts is actively counterproductive here. Because reach is governed by the proportion of your audience that engages, adding unresponsive accounts lowers that proportion and shrinks reach on everything you publish afterwards. The engagement guide explains the arithmetic.
