Why not every follower sees your post

Many people assume a follower sees every post. In fact the feed hasn’t been in time order for years: on Instagram since 2016, on Facebook even earlier. Both networks build a separate order for each person. According to Instagram head Adam Mosseri, in a chronological feed people were missing about 70 % of posts — almost half of them from close friends.

1 / 4How the feed is built

Facebook describes this process in its Transparency Center. Put simply, it happens in three steps.

1. 01
   First, the candidates

   The feed gathers every post it could show you: from the pages and people you follow, and from recommendations.

2. 02
   Then, the prediction

   Using thousands of signals, the system estimates in advance how likely you are to watch a post to the end, like it, comment on it or send it to someone.

3. 03
   Finally, the order

   Each post gets a relevance score and the feed is sorted by it. That is why two followers see completely different feeds at the same minute.

2 / 4What Instagram looks at

1. 04
   Watch time

   How long a person stays with your video or post. In January 2025 Mosseri named it among the three signals that matter most.

2. 05
   Likes per reach

   Not the number of likes but the share: how many liked it out of those who saw it. 50 likes on 200 views beats 50 likes on two thousand.

3. 06
   Sends per reach

   How many people forwarded the post to a friend in a direct message. According to Mosseri, this matters more when the post is shown to people who don’t follow you yet.

3 / 4What you can change yourself

1. 07
   Lead with the point

   The first second and the first line decide whether someone stops scrolling. In a video, show the result or the question right at the start.

2. 08
   Ask a question

   End the post with something simple that can be answered in one word. It is easy to reply to, and a comment is a good signal for the system.

3. 09
   Write what people forward

   A tip, a list or a useful fact — the kind of thing you would send a friend with “look, this is about you”.

4. 10
   Reply to comments

   Your reply reaches the person as a notification and they may come back to the post. A conversation under a post is a good signal too.

4 / 4How the reader sees the feed

1. 11
   Favorites

   On Instagram you can add up to 50 profiles to Favorites: their posts rank higher in the feed. The profile owner is not notified.

2. 12
   Feed in time order

   Tapping the Instagram logo opens a chronological feed: Favorites only, or everyone you follow. But by default the ranked feed still opens first.

3. 13
   “Why am I seeing this post?”

   On Facebook this item is in the post menu: it shows what pushed the post up in your feed. A good way to understand how the feed thinks.

✓The bottom line

Follower count only gives you a chance. The post is shown to those the system thinks will find it interesting. So the page that grows is the one whose posts get watched, liked and sent to friends.
