Most agency social content is invisible because it could have been posted by any business in your sector, and readers scroll past anything that does not sound like a specific person who knows something.
If you have ever looked at your own feed and thought "that is nice, and it tells nobody anything", you have seen the problem. The calendar is full, the graphics are tidy and nothing happens.
This guide explains why that happens, what the available data says about it, and three post formats worth testing instead. It belongs with our broader guide to hiring a social media marketing agency in the UK.
Why generic agency content disappears
Generic content fails because it has no information in it. A post that says "Happy Monday from the team" or "Here are five tips for a productive week" gives a reader nothing to learn, disagree with or reply to, so they do nothing.
It happens because an agency working from a calendar often has a dozen or more posts to fill each month for a business it speaks to rarely. With no real material to hand, it fills the gap with seasonal greetings, quote cards and tips that could apply to anyone.
Look at the idea lists that rank for this search. One widely read list recommends polls, giveaways, ask-me-anything sessions and posts for "National" days. Those are formats, not content. They tell you how to wrap a post and nothing about what it should say.
What the engagement data shows
There is real evidence that generic posts do worse. It is not perfect, and it is worth reading carefully.
Originality.ai analysed 3,368 long-form LinkedIn posts from 99 influential profiles across 11 industries, published in 2025. It classed 53.7% as likely AI-written. In the marketing and branding category, its figures show posts it classed as human-written averaging 771 interactions, against 207 for those it classed as AI-written. PPC Land's report on the study has the full table.
Treat that with care. Detector scores are probabilistic, the profiles are different sizes, and Originality.ai's own percentage gaps do not match its raw averages. The direction is still clear: in marketing content, posts that read as human got far more reaction.
Edelman and LinkedIn's 2024 survey of B2B decision-makers points the same way. They found that decision-makers trust thought leadership more than marketing materials, and 54% said it made them realise other vendors might understand their challenges better. Ragan's summary sets out the findings.
What invisible content has in common
Four traits are common in posts that underperform.
They have no first-hand detail. Nothing in the post shows the writer has met a customer, fixed a problem or made a mistake.
They have no number. A figure from your own work, even a small one, gives a reader something to remember.
They have no opinion. A post that nobody could disagree with attracts no comment.
They could be moved to a competitor's page without changing a word. That test is the quickest one to run on a calendar. Take any post, swap in a rival's logo, and see if it still makes sense.
Three post formats worth testing
We cannot claim these three earned a measured number of comments for any named client, because we have no data we could publish. They are the formats we would test first, because each forces real material into the post.
The answered question
Take a question a customer asked this week and answer it in 150 words. Start with the question as asked, in the customer's wording, with the name left out.
A dental practice might answer "Is it normal for a crown to feel high for a few days?" An accountancy firm might answer "Do I have to register for VAT if I sell through a marketplace?" A retailer might answer "Why was my delivery split into two parcels?"
Readers with the same question stop. Readers with a different answer reply. Both outcomes beat silence.
The number from your own work
Pick a figure from your records and say what it means. It can be small: the average time to reply to an enquiry, the share of orders that arrive on time, the number of appointments missed last month.
State what you did about it. A number with no action reads as bragging. A number followed by "so we changed X" reads as someone running a business.
Keep it honest. If a figure is from a small sample, say so. Readers trust a firm that admits how little it knows more than one that claims too much.
The walkthrough document post
Turn one process you explain often into a short PDF the reader can swipe through. A checklist, a decision tree or a "what happens at each step" works well.
LinkedIn business-page data supports the format. Socialinsider's 2026 benchmark covered 1.3 million posts from 16,645 pages across 2024 and 2025. It found native document posts generated the highest engagement of any format, with an average of 7.00% against 5.20% for all pages. Social Media Today's report covers the study, and our guide to making a LinkedIn document post in 20 minutes shows how to build one.
Rewriting a generic post
The fastest way to see the difference is to rewrite one. Here is a typical calendar post for a small accountancy firm: "Tax season is coming! Make sure you are ready with our top tips." It could be posted by any firm in the country.
Now start from something that could happen. Imagine a client rings because a letter from HMRC has arrived and they are unsure whether to pay. The rewrite is a short post saying what the letter looked like, the two questions to ask before paying, and where to check it is genuine on gov.uk. Names and figures are removed.
The first post gets a like from a colleague. The second gets a comment from someone who received a similar letter. One of those people may become a client.
A retailer can do the same. "New stock in!" becomes "Several customers have asked this week whether the new oak range comes with a matching shelf. It does, and here is the lead time." A dental practice can turn "Smile!" into the answer to a question patients ask at reception.
The pattern is the same each time: begin with a real event, say what a reader should do about it and leave out anything that is only decoration.
How to get this material without being a writer
You do not need to be a good writer. You need a way to capture what already happens in your business.
Keep a running note of customer questions, objections and surprises. Add to it daily. Once a fortnight, spend 30 minutes turning five of those notes into posts.
If that is too much, record a 20-minute call with the person who knows most about a topic and have someone else shape it. Content repurposing done properly walks through how a single call becomes a month of posts, including the consent step.
What to ask your agency to change
Ask the agency where its last ten posts for you came from. If the answer is "a content calendar", the posts have no connection to your customers.
Then ask it to sit in on one customer call a month, or read your enquiry inbox. Give it access to your CRM notes if they exist. An agency that cannot get close to your customers cannot write anything specific about them.
Put the request in writing in your brief. Our template, how to brief a social agency, includes the section that most briefs leave out: what the agency may and may not say.
When to keep the generic posts
Some generic posts are fine. A bank-holiday opening-hours notice or a staff announcement serves a purpose. Retailers and local firms often need these.
The problem arises when generic posts make up most of the calendar. A reasonable mix is one generic post for every four specific ones. If it is the other way round, the agency is filling space.
Retailers and ecommerce brands tend to have more everyday material than professional firms: product questions, delivery quirks and customer photos. They can run a higher share of lighter posts, as long as each says something about a real product or order.
Dental practices and clinics have to be careful with patient material, so lean on questions and process explanations, not individual cases.
How to tell if the content is working
Count comments from people who might buy, not total likes. A post with eight comments from prospects and peers is worth more than one with 80 likes from staff and friends.
Then count conversations. How many direct messages, enquiries or calls mentioned a post? Our guide on why "followers up, sales flat" is the commonest agency failure sets out the measurement that goes with this.
