The number that matters is the one you can keep
Advice about posting frequency is usually derived from what high-performing accounts do, which inverts cause and effect: accounts with resources post more, and accounts with resources also perform better for a dozen other reasons. Copying the frequency without the resources produces three excellent weeks followed by a month of silence, and the silence costs more than the extra posts gained. Pick a number you can hit in your worst week, not your best one.
X: frequent, because posts have almost no shelf life
X posts are effectively invisible within a few hours, which means frequency is doing most of the work. One to three posts a day is a reasonable working target for an account that matters to the business; several a week is the realistic floor below which the account stops registering at all. The saving grace is that X posts are cheap to produce — they are short, they can be reactive, and they do not need an asset.
LinkedIn: less often, but each post has to earn it
LinkedIn posts have a longer life and a less forgiving audience. Two to four times a week is plenty for most accounts, and daily posting is only worth attempting if you genuinely have something to say daily. The failure mode here is not infrequency, it is filler: LinkedIn punishes an account that posts five times a week of which three are obviously padding, more than it rewards the raw cadence.
Instagram: consistency over volume
Three to five times a week across feed and short-form video suits most accounts. The grid makes your consistency visible in a way no other network does, which cuts both ways — a steady three a week looks deliberate, while a burst of ten followed by nothing looks abandoned. Because Instagram content is asset-dependent, the sustainable number is usually set by how much shooting and editing capacity you have, not by how much you can write.
TikTok: the one network where more genuinely is better
TikTok is the clearest case for volume, because distribution is driven by the platform rather than by your following, and more posts mean more chances at that distribution. Daily is the ambition; three to five a week is a solid working cadence. This is also the network where batching pays off most, because the production is the whole cost and the posting is trivial.
YouTube: as often as quality allows, and no more
Weekly is the classic cadence for long-form, fortnightly is perfectly respectable, and Shorts can run on their own faster rhythm alongside. YouTube is the network where publishing something underbaked does the most lasting damage, because the video stays in front of your channel indefinitely. Consistency of schedule matters here — audiences learn when to expect you — but not at the cost of putting out something you would rather not have made.
- X: one to three a day, several a week as a floor
- LinkedIn: two to four a week, and nothing you would call filler
- Instagram: three to five a week, limited by asset production
- TikTok: three to five a week, daily if you can batch it
- YouTube: weekly to fortnightly for long-form, Shorts on their own cadence
Set the floor, then let batching raise the ceiling
The practical way to hold a cadence you could not otherwise sustain is to decouple creating from publishing. If you have to be present at the moment of posting, your frequency is capped by your attention. If you write and queue a fortnight in one sitting, it is capped by your writing throughput on a good day — which is considerably higher. This is the entire reason scheduling tools exist, and it is why the accounts that look relentlessly consistent usually are not being run by relentlessly consistent people.
Then ignore all of this in favour of your own data
These numbers are a starting point for an account with no history. Once you have a few months of your own, your audience will tell you something more useful than any benchmark — that your Tuesday posts outperform everything, that your audience is not where you assumed, that the fifth post of the week never lands. Treat the general advice as scaffolding to be removed once the building stands up.
