Your feed is not a list of everything your prospects posted. It is the result of several rules applied in a fixed order. Once you know that order, both questions people usually have become easy to answer: why this post is in front of me, and why the one I expected is not.
The short version
Extrovert collects recent posts from the people and topics your campaigns follow.
Your campaign filters decide which of those posts are allowed through at all.
Your commenting pace decides which people are available to comment on right now.
Only one post per person is offered at a time.
Your sorting strategy decides what comes first.
If you work in Main Feed, your campaigns are mixed together by the priority you gave them.
Each step only ever removes or reorders. Nothing added later can put back a post an earlier step filtered out.
1. What gets collected
Extrovert checks each prospect once every 24 hours, and you can run one extra check per hour yourself. Collecting is separate from your working hours, which only control when comments are sent.
Posts older than 30 days leave on their own, so that is the widest window anything can work with. See how frequently the feed refreshes.
2. What your campaign lets through
Filters run before anything else and they are absolute. A post that fails one never reaches you, no matter how important the person is.
Post age limit, 28 days unless you changed it.
Post categories you chose to exclude.
Filter by your custom topics, if you switched it on.
Minimum reactions, on topic campaigns only.
Whether the campaign is commenting on posts a prospect is only likely to see. With that off, none of those posts appear.
All of these live in commenting settings.
3. Who is available right now
A post can pass every filter and still wait, because of the person attached to it.
Commenting pace per prospect. If you commented on someone recently, their other posts stay hidden for the number of days you set.
Change pace or stop after several comments. Once someone reaches the number you set, they either slow down or stop appearing entirely.
Work already in flight. If you have approved a comment for someone, or one is being written or published, no further post of theirs is offered until it settles.
For a post by somebody else that your prospect is likely to see, the person these rules apply to is the prospect you are warming up, not whoever wrote the post. Several such posts by different authors still count as one relationship.
4. One post per person at a time
Whatever is left is grouped by person, and only that person's best-ranked post is shown. Their other posts are not gone. They wait behind it and come up once you have dealt with the first.
This is why a prolific poster does not flood your feed, and why acting on one post can make another appear.
5. What comes first
Now the order is decided. On a prospect campaign, people you marked as important come first whichever strategy you picked. After that:
Newest first orders by the most recently published post.
Finish warm-up first orders by who needs the fewest remaining comments to reach their outreach target. People with no target come last.
Spread evenly orders by who you have gone longest without commenting on. People you have never commented on come first.
Marking someone important changes the order only. It does not let their posts skip your filters or your commenting pace.
A person's own posts are preferred over posts they are only likely to see, but only as a tie-break. Under Newest first, a fresher post they are likely to see can still come up before an older post of their own.
Only published comments feed any of this. A draft, an approval and a queued comment do not count until they are actually live.
Topic campaigns have no prospects, so they have no sorting choice. Their feed is always newest post first.
6. Mixing your campaigns
Everything above happens inside one campaign. Main Feed then takes those finished lists and interleaves them, taking more often from campaigns you set to High priority and less often from Low.
Priority never reorders anything inside a campaign. It only decides whose turn is next. A post that several campaigns are tracking appears once, and the counts on the tabs count it once.
Main Feed also leaves out campaigns that are stopped or set to comment automatically, because neither has anything waiting for your approval. Their own campaign feeds still show their posts.
Why a post you expected is not there
Work down this list. The causes are ordered roughly by how often they turn out to be the answer.
You already have something in flight for that person. Check Pending. One approved comment holds back the rest of their posts until it publishes.
You commented on them recently. That is Commenting pace per prospect doing its job.
Another of their posts is in front. Only one comes up at a time. Deal with it and the next appears.
The post is older than your Post age limit. The default is 28 days, and some campaigns are set much tighter.
They reached your stop threshold. Check Change pace or stop after several comments. Turning it off brings them straight back.
The post's category is excluded. Note that once you exclude any category, posts Extrovert could not classify are filtered out too.
Your custom topic filter is on and the post does not match one of your topics.
It went to Skipped. Either you skipped it, or Limit posts per prospect set it aside because that person had newer posts. It comes back with Move back for approval.
It is an indirect post and that setting is off. Without Comment on posts they are likely to see, none of them appear.
It arrived after you opened the feed. New posts do not push into a feed you are working in. Click Refresh feed.
It is already dealt with. Check Pending, Posted and Error before assuming it vanished.
You are in Main Feed and the campaign is stopped or on Auto. Open that campaign directly.
If none of these explain it, the post may simply not have been collected yet. Run Check for new posts and give it a few minutes.
