A best time to post tool reads how your own audience engaged with your past posts and turns that into suggested slots, then schedules your next posts into them. The method is the same in every product: collect a few weeks of posting history, let the tool rank the hours, post into the top slots, and check the results. No tool can skip the first step. Without history, a tool either shows no suggestions or falls back to averages from other accounts, which is exactly what a published study already gives you for free.
What a complete best-time solution needs
Finding the best time to post on social media is not one feature. It is a small system with four parts, and most tools cover some of them well and others not at all.
- Your own audience data. Engagement on your past posts, or a chart of when your followers are online. This is the raw material.
- A ranking. Something that turns the data into a short list of slots per network and per day.
- Scheduling into the slots. A queue or calendar that puts the next post into a top slot without you copying times by hand.
- A check. A way to see whether posts in the suggested slots actually did better, so the ranking keeps earning your trust.
Time zones run through all four. If your analytics, your scheduler and your audience sit in different zones, every slot is off by the difference. The free native apps cover part 1 and some of part 2. The paid schedulers below cover parts 2 and 3, each in its own way. Part 4 stays your job everywhere.
Start free: your network's own active-hours chart
Before paying for an optimal send time feature, read what the networks already show you. Meta's help page lists the times your followers are most active on Instagram among the follower insights public accounts see once they have at least 100 followers [1]. TikTok's Creator Academy describes a Most active times section in TikTok Studio's Viewers tab, covering the last 7 days, and a Followers tab that breaks habits down by hours and days [2]. Write down the top three hours per network, post into them for two weeks, and compare results at the same age.
Published studies are a fair starting guess too. Buffer's best-time study for Instagram, published September 23, 2026, ranks days and hours from posts sent through its own app [3]. It is an average across other accounts, not your followers. Our guide to the best time to post on Instagram shows how to use studies as a first guess, and the step-by-step routine for finding your own best time walks through the free method on TikTok and Instagram.
The free way stops when you run several networks or clients. You read each app separately, copy hours into a spreadsheet and paste them into a scheduler. That is where a tool earns its place.
Compare the slots a tool suggests with the most active hours in your native analytics. Where both agree, trust the slot; where they differ, test both for two weeks.
Tools that suggest the best time to post from your own data
The products below each rank slots from your account's history. They differ in how much history they want, which networks they read, and whether they fill the slots for you or just show them.
For teams that want the best slots ranked for them
Optimal Send Times in Compose ranks the top seven send times for the chosen day from each profile's engagement; the Queue with ViralPost publishes queued posts at those times automatically.
- Pick profiles and a day in Compose
- Open the Optimal Send Times dropdown
- Or switch the profile's Queue to ViralPost
Sprout Social's Optimal Send Times sit in Compose and show the top seven suggested times for the selected profiles on the chosen day, ranked by stars. The model reads 16 weeks of engagement per profile, refreshes each Sunday and scores every five-minute step of the coming week. Switch the Queue to ViralPost and queued posts go out at those times on their own. Thin profiles get aggregated network and time-zone data instead.
Recommended times are built from your last 30 days of results and appear as up to three slots a week in the calendar when you turn on recommended times for scheduling.
Hootsuite builds recommended times from your last 30 days of results. Turn on the calendar option to show recommended times when scheduling, and up to three slots a week appear. It needs at least three posts with some engagement in that window per account.
For creators and small brands on Instagram and TikTok
Best Time to Post, switched on from the calendar, ranks your top seven Instagram times from six months of engagement and one TikTok time per day; saved times become Quick Schedule slots.
Later's Best Time to Post is switched on from the top of the calendar. For Instagram it lists the top seven times from the last six months of engagement; for TikTok it gives one best time per day. You can save those times as Quick Schedule slots in the mobile app, and our guide to scheduling Instagram with Later shows that routine.
Best Times shows a color-coded heatmap on the Planner calendar from your audience's activity; click a dark slot to schedule there, or let recurring posts take the best available time.
Metricool draws Best Times as a color-coded heatmap on the Planner calendar, where a darker cell means a better hour. Clicking a slot sets the post there. Our walkthrough of the Metricool Planner covers the heatmap next to scheduling and bulk imports.
For several profiles and category-based posting
Pick Optimal Times in the Compose box and Sendible schedules at hours learned from your posting history; queues can hold up to three Optimal Times per day.
Sendible's Optimal Times are a choice in the Compose box, learned from your own posting history. They are calculated across all profiles in your account, not per profile. That fits best when the profiles share one audience, such as one brand on several networks.
When you schedule a post at a specific time, the editor suggests an hour from your analytics for that account, category and day; a Preset Schedule covers the weeks before data exists.
SocialBee suggests an hour while you schedule a post at a specific time, weighing the account, the content category and the strongest hour for that day. Our SocialBee for Instagram guide shows the suggested times next to the preset schedule and the grid.
A partial fit: general suggestions
The composer suggests recommended posting times for a chosen day, based on general engagement data from active accounts, which gives a reasonable first schedule.
Buffer's composer can suggest recommended posting times for a given day, but those come from general engagement data across active accounts, not your audience. Its Insights has no best-time report. That is fine for a first schedule, and it is the same kind of average a study gives you.
Two combinations that cover the gaps
No single product covers all four parts for every network. Two pairings work well.
Free charts first, a tool once history exists. Read Instagram Insights and TikTok Studio for your first month. Use those hours as manual slots in whichever scheduler you already have. Once the account has a few weeks of posts, switch on the tool's own suggestions and compare them with what the native charts showed. When both agree, trust the slot. When they disagree, test both.
A preset schedule, then data. SocialBee's Preset Schedule builds a posting plan for chosen categories and profiles before any data exists. Start there, then move slots toward the suggested hours as your analytics fill in. The same logic works in Sendible: its queues can hold up to three Optimal Times per day, but they do not refresh on their own. Edit the queue every few weeks so the slots follow the newer data.
Every tool here needs posting history or a follower minimum first. Until then, you get no suggestions, or network-wide and study-based ones, not your audience.
Where every best time to post tool stops
Each tool is honest about one limit: it needs history. Hootsuite wants three engaged posts in 30 days. Metricool needs at least 100 followers and shows Best Times up to seven days after you connect. Sendible needs a few weeks of posting data. Sprout falls back to network-wide data for thin profiles. A brand-new account gets averages or nothing at all.
The networks themselves set the second limit. According to Metricool, Meta stopped supporting best times in its API on September 24, 2024, so Facebook accounts connected after that date get times from general behavior studies, not their own audience; LinkedIn and YouTube work the same way there. Later does not offer Best Time to Post for LinkedIn. So for LinkedIn, the honest answer is often your own test.
The third limit is what a suggestion is. Sprout's recommendation is a prediction from past engagement, not a chart of when your audience is online. Metricool's Best Times keep no stored history, so past and future weeks show the same slots. A suggestion is a hypothesis. Your results decide.
Queues that store best times, such as Sendible's, do not update on their own. Edit them every few weeks so the slots follow newer data.
How to choose an optimal send time tool
Pick by situation, not by brand. Ask four questions.
| Your situation | Look at first |
|---|---|
| One brand, mostly Instagram and TikTok | Later, Metricool |
| A team that wants posts released at the best slot automatically | Sprout Social (ViralPost queue) |
| A team that wants weekly recommended slots in the calendar | Hootsuite |
| Several profiles under one brand, evergreen content by category | SocialBee, Sendible |
| A first schedule with no history yet | Buffer's suggestions, or a published study |
Which networks matter most? If LinkedIn is your main channel, look at Hootsuite or Sendible, whose times cover LinkedIn (on Hootsuite, LinkedIn profiles only on some plans); Metricool uses general studies there and Later skips it. Plan on testing those slots yourself too. If Instagram and TikTok lead, Later and Metricool both read them, with account-type rules: Later needs a TikTok Business account and an Instagram Business or Creator profile connected to a Facebook Page.
Do you want suggestions or automation? Suggestions you pick per post are in Later, Metricool, SocialBee, Sendible and Hootsuite. Sendible queues can hold up to three Optimal Times per day, but you refresh them by hand, and Metricool can give recurring posts the best available time. A queue that keeps applying fresh best times without your edits is Sprout's ViralPost.
How many profiles? Later's multi-profile Best Times start on Growth. Hootsuite calculates times for up to 100 accounts, the ones with the most followers. Sendible pools all profiles in one account into a single calculation.
How much history do you have? Less than a month means a tool will mostly echo averages or show nothing. Start free, post consistently, then let a tool take over.
Frequently asked questions
Do tools that suggest the best time to post use my own data?+
Most do: Sprout Social, Hootsuite, Later, Metricool, Sendible and SocialBee rank slots from your own history. Buffer's suggestions come from general engagement data across active accounts.
What is optimal send time in social media?+
It is a scheduler's prediction of when a post will get the strongest engagement, based on how your past posts performed. Sprout Social calls its version Optimal Send Times; Sendible calls it Optimal Times.
Why does my scheduler show the same best times for Facebook as everyone else?+
According to Metricool, Meta stopped supporting best times in its API on September 24, 2024, so Metricool gives Facebook accounts connected after that date times from general behavior studies.
Is there one best time to post on social media for all networks?+
No. Each network has its own audience habits, so read each one's active hours and test each network separately.
The bottom line
A best time to post tool is only as good as the history you give it. Read your free native charts first, post consistently for a few weeks, then let a scheduler rank and fill the slots. Sprout Social suits teams that want the queue released at the best times automatically, Hootsuite suits teams that want recommended slots in the calendar; Later and Metricool suit Instagram and TikTok-led brands; SocialBee and Sendible suit category and multi-profile posting; Buffer gives general starting slots. Whatever you pick, compare the suggested slots with your results every couple of months and keep what wins.
