What Makes the Algorithm Boost a Post

Why this matters

Platforms give preferential distribution to posts that demonstrate early engagement velocity, shares, and saves — these signals tell the algorithm the content is worth amplifying before it risks showing it to a wider audience. Knowing which specific triggers exist on each platform lets you write content and time posts to maximize those early signals.

Try it yourself

1. Post two similar pieces of content — one with a question CTA ('what do you think?') and one without — and compare comment counts and reach 24 hours later.
2. Look at your analytics for the posts with your highest reach and check whether they also show an above-average save or repost rate compared to your median.
3. Find a post that got strong early engagement in the first hour — note the reach at 1 hour vs. 24 hours and calculate the multiplier the algorithm applied.
