Posting every day on LinkedIn for 90 days is worth trying only if you decide in advance what you will count, because impressions alone will tell you nothing about enquiries.
We could not find a published test that follows one business through 90 days of daily posts and reports the enquiries it produced, so this LinkedIn posting strategy does not pretend to have one. It uses the largest frequency study we could find, sets out a plan you can run yourself, and shows how to measure it honestly.
It sits inside our wider guide to social media marketing agencies in the UK. Two companion guides matter most: one on founder-led LinkedIn against a company page and one on daily commenting.
What the data says about how often to post
The best evidence we found is Buffer's analysis of more than 2 million LinkedIn posts from over 94,000 accounts, published in August 2025. Compared with the same accounts posting once a week, accounts posting two to five times a week got about 1,182 more impressions per post. Accounts posting six to ten times a week got about 5,001 more, and those posting 11 or more got about 16,946 more.
Engagement rate rose with frequency too: 0.23 percentage points higher at two to five posts, 0.76 at six to ten and 1.40 at 11 or more.

A daily post is seven a week, so it sits in the middle band. Buffer itself calls two to five posts a week the sweet spot for reach without overwhelming a schedule, and says the jump from one to two to five is where gains begin.
What the frequency data does not tell you
It tells you about reach, and reach is not enquiries. Buffer's study measured impressions, engagements and engagement rate. It did not measure leads, and the authors say low-quality content posted often "won't yield great results".
It also compares accounts against their own earlier weeks, so it shows that the same people got more reach when they posted more. It does not prove that posting more caused a sale. Buffer sells scheduling software, which gives it a reason to like the finding.
For UK B2B in particular, Whito, a UK agency, says three to five posts a week from a personal profile is the sweet spot. It gives no source for that figure, so treat it as one practitioner's view.
Account size matters less than you might expect. Buffer reports that smaller accounts saw similar relative lifts, although it gives no size-specific figures. That is encouraging for a founder with a few hundred connections, and it is not proof.
Why daily might still be the wrong target
Five posts a week is the better starting point for most founders. It covers the working week, leaves weekends alone and sits inside the band where the biggest gains appear.
Seven posts a week means thinking of something worth saying 365 times a year. Most small firms do not have that much to say that is specific, and the posts that fill the gap are the generic ones we describe in why most agency social content is invisible.
If you can post daily without repeating yourself, do it. If you find yourself reaching on day 12, drop to five and keep the quality.
A 90-day plan you can run yourself
Run it in three blocks of about 30 days. The point of the blocks is to change one thing at a time so you can tell what worked.
Days 1 to 7: set the baseline
Before you publish anything, write down the starting numbers. Count your followers, your average profile views a week, and the enquiries you got in the last 90 days, with how each one found you.
Ask your sales team or yourself where the last ten enquiries came from. If LinkedIn is not on the list, that is useful to know before you start.
Days 8 to 37: post five times a week
Post every weekday. Mix three kinds of post: something you learned from a real customer problem, a number from your own work, and a short opinion on something in your sector. Keep each under 200 words.
Spend ten minutes a day replying to comments on your own posts and on other people's. That is covered in the guide to a 15-minute LinkedIn comment routine.
Days 38 to 67: add the formats that earn more
Add one document post a week. Socialinsider's 2026 benchmark of 1.3 million business-page posts found native documents average 7.00% engagement, against 5.20% across all formats. That is a company-page figure, so check it against your own results.
Keep the other four posts as they were. If the document post beats them, do more. If not, drop it.
Days 68 to 90: test a daily rhythm
Now try seven posts a week for three weeks, but only if the first two blocks felt easy. Compare profile views and enquiries per week against the first 60 days, not against the week before.
What a posting week looks like
A week of five posts needs a repeatable shape, or you will spend Sunday evening staring at a blank box. This is the shape we would start from for a founder or partner at a small B2B firm.
| Day | Post | Source of the material |
|---|---|---|
| Monday | A question a customer asked this week, answered in 150 words | Your inbox or call notes |
| Tuesday | A number from your own work and what it means | Your own records, anonymised |
| Wednesday | A mistake you see in your sector, and the fix | Something you corrected recently |
| Thursday | A short opinion on a news item in your field | Trade press, a regulator's update |
| Friday | A document post that walks through one process | A checklist you already use |
Every post comes from something you did that week, which is why the plan works for people who say they have nothing to write about. The material is already in your diary. The job is to notice it.
Keep a note on your phone and add to it whenever a customer says something surprising. Ten minutes on that note on Sunday gives you the week.
Who should not post every day
Do not post daily if the posts would come from a ghost writer who has never spoken to your customers. Readers can tell, and LinkedIn will not hide it.
Do not post daily if nobody will reply to the comments. A post that gets six replies you ignore does more harm than a quiet week. Commenters are the people most likely to become enquiries, so a founder who posts and vanishes is wasting the reach.
Do not post daily as a substitute for fixing your offer. If your website does not explain what you do and who for, more visitors will not help, and our web design service usually gives a better return first.
A regulated firm needs one more check. Anything that describes your services or results may need sign-off under your regulator's advertising rules, so decide who approves posts before day one.
How to measure enquiries, not impressions
Track four numbers each week in a spreadsheet: posts published, profile views, new conversations that started on LinkedIn, and enquiries that mention LinkedIn.
The last two are the ones that matter. Add a "how did you hear about us" field to your contact form and ask on every call. People forget where they found you, so also note whether the enquirer connected with you on LinkedIn in the previous month.
If you run a CRM, add LinkedIn as a source value. If you use tracked links, tag them so your analytics shows LinkedIn as the source. Then an enquiry that arrives three weeks after a post is not lost.
For the numbers beyond those four, our guide to followers up, sales flat explains which vanity metrics to ignore.
What to expect from 90 days
Expect more profile views and a few conversations, not a flood of leads. LinkedIn work compounds slowly because most people who see your posts are not buying yet.
Marketing Week's piece on the 95:5 rule, written by Peter Weinberg and Jon Lombardo of LinkedIn's B2B Institute, cites research that only about 5% of B2B buyers are in the market at any time. The rest are not ready, and the brand they remember is the one they call. Ninety days of posting builds that memory. It rarely closes a sale inside the period.
Edelman and LinkedIn's 2024 research supports the long game. In it, 86% of decision-makers said they were somewhat or very likely to invite consistent, quality thought leadership creators to a tender, though only 38% of creators expected it.
When to stop or change course
Stop or change the plan if, after 60 days, your profile views have not moved and nobody has mentioned a post in a conversation. That usually means the topics are too general or the audience is wrong, not that LinkedIn does not work for your sector.
Look at who is viewing your profile. If they are other marketers and recruiters, not people who buy from you, change what you write about before you change how often you write.
Accountants, consultancies and other professional services firms tend to have long sales cycles, so judge them over six months, not three.
