Where to Find Content Ideas to Post on LinkedIn When You've Got Nothing to Say

The short version: the best LinkedIn content ideas are not in your head, they're already sitting in your inbox, your sales calls, your old blog posts and the comments section of your last five posts. You don't need a content calendar full of trending topics, you need a habit of capturing what you already say out loud every week and turning it into a post.

Your calendar is not the problem, your capture system is

I get this question at least three times a week, usually from someone who has just committed to posting on LinkedIn five days a week and has gone completely blank by Wednesday. The honest issue isn't a lack of ideas. It's that nobody wrote them down when they had them.

I keep a note on my phone called "LinkedIn scraps". Every time a client says something interesting on a call, every time I get annoyed by bad advice in my feed, every time someone asks me the same question for the third time that month, it goes in that note. Right now it has 34 lines in it. That's roughly six weeks of posts, and I didn't sit down once and "brainstorm" any of them.

Start with what's already in your inbox and your DMs

This is the one nobody tells you because it feels too obvious to be useful, but it's the single highest-yield source I've got. Search your sent folder for the last ten emails where you explained something to a client. Those explanations are posts. If you've typed it out once to help one person, it will help a hundred more.

Same goes for your LinkedIn DMs. Scroll back through the last month of messages you've sent and count how many times you've explained the same thing. I did this exercise once and found I'd explained "why your open rates dropped after Apple's Mail Privacy update" to four separate people in three weeks. That became a post that got 214 comments, because it turns out a lot of people had the same quiet confusion and nobody had said it plainly yet.

Client conversations are a goldmine, if you're paying attention

A few years ago I was on a call with a client who'd just fired their agency after eighteen months and £40,000 with almost nothing to show for it. She was embarrassed to tell me. I posted about it that evening, no names, just the shape of the story: bright agency pitch, vague monthly reports, a director who couldn't explain what "engagement" meant when she asked directly.

That post did 41,000 impressions and pulled in three discovery calls that week, more than any polished "5 tips" post I'd written in months. People don't remember your tips. They remember your stories, especially the ones that make them think "oh thank god, it's not just me."

The rule I use: every real client conversation has a post in it somewhere, you just have to strip out anything identifiable and keep the emotional shape intact. Frustration, relief, surprise, that awkward moment when someone finally says the quiet part out loud. That's the content, not the case study stats.

Your competitors' comment sections

Go to five posts from people in your industry with 50 or more comments. Read every single comment. You're looking for two things: the question that keeps repeating, and the disagreement nobody resolved. Both are posts waiting to happen. If forty people are arguing in the comments about whether cold email is dead, that argument is your next post, and you get to be the one who settles it with an opinion instead of sitting on the fence.

Steal shamelessly from other platforms (, not lazily)

LinkedIn is the only platform where I see people acting like ideas can only come from LinkedIn itself. That's backwards. Some of my best-performing posts started life somewhere else entirely.

If you're already writing for other channels, mine them. I wrote a piece on how to write and schedule an Instagram post for a business and realised halfway through that the actual planning process I described made a perfectly good standalone LinkedIn post on its own, just with the fluff stripped out and the tone flattened to sound less like a caption and more like advice from a person.

Facebook groups are another underused well. I put together a guide on where to find Facebook groups aimed at marketers, and those groups are full of raw, unpolished questions from people who haven't yet learned to phrase things the "professional" way. That rawness is gold. Someone asking "why does nobody engage with my posts anymore, am I doing something wrong" in a Facebook group is a better content prompt than any AI idea generator will give you, because it's a real person's actual anxiety, not a keyword.

Old blog content works too. I once dug back through a piece I'd written on which blogging platforms pay you for content and turned three separate paragraphs from it into three separate LinkedIn posts over three weeks, each with a different angle and a different opening line. Nobody noticed it was one source. Nobody needs to.

Look at what's new in your field, even if it feels off-topic

Some of the widest-reaching posts I've written have come from noticing a shift somewhere adjacent to my usual topics, not directly in them. When wearables started getting serious about capturing content on the move, I wrote about what wearable technology means for the future of content creation, and the LinkedIn version of that piece did better than most of my straightforward marketing posts that month, purely because so few people in my feed were talking about it yet. Being early on a topic beats being thorough on a topic everyone's already covered to death.

The same logic applies if you're watching other creators experiment with formats. I've written before about finding your TikTok drafts before they disappear, and honestly, half the value of that post for LinkedIn purposes wasn't the TikTok tip itself, it was noticing that "here's a small technical fix that's been quietly annoying everyone" is a content format that travels well across every platform, including LinkedIn.

LinkedIn's own features, used

Most people ignore the tools LinkedIn hands them for free. Three worth using every week:

• The "Trending now" news module on the homepage sidebar. Ninety percent of it is irrelevant to you, but that other ten percent will occasionally hand you a topic three days before it peaks in your industry.
• LinkedIn's search bar itself. Type a topic and filter by "posts" and sort by "top". You'll see exactly what's already performing on that subject, which tells you both what's saturated and what angle hasn't been covered yet.
• Your own analytics. Go into your post performance and sort by impressions over the last 90 days. Whatever your top three posts have in common (a format, a tone, a topic) is your next batch of ideas, not something brand new.

The uncomfortable bit: original ideas are overrated

Here's the part most people writing about LinkedIn content don't want to say plainly. Nobody remembers your last post. LinkedIn's own reach data has shown for years that most posts are seen by a tiny fraction of your audience, often under five percent, before the algorithm moves on. That means the person who "already saw that" from you three months ago almost certainly didn't.

I have republished the same core idea, worded differently, four separate times over two years, and every single time it performed within the same range because it's good advice and most of my audience simply wasn't there the first three times. The people chasing constant novelty are burning themselves out for an audience that mostly wasn't watching anyway. Your job isn't to never repeat yourself. It's to say the true, useful thing often enough that eventually the right person is scrolling when you say it.

That single mindset shift solves the "I've run out of ideas" problem faster than any list of prompts, because it means your best posts from eighteen months ago aren't finished, they're a draft folder.

A simple weekly system that works

Here's exactly what I do, no app, no fancy dashboard:

• Monday morning, ten minutes: scroll my "LinkedIn scraps" note and pick two things to write about that week.
• Every client call, I keep a notes doc open and flag anything worth stealing (with permission if it's specific enough to identify anyone) with the letters "LI" so I can search for it later.
• Friday afternoon, I check my post analytics from the previous four weeks and note which one did best, then plan one follow-up post on the same theme for the week after.
• Once a month I do the competitor comment-section read, roughly 45 minutes, and it usually generates three to four post ideas on its own.

That's the whole system. It generates more ideas than I can use, which is the actual goal, not a clever prompt list, just a habit of catching things before they evaporate.

Frequently asked questions

How often should I post on LinkedIn to see real results?

Three to four times a week is enough for most small businesses and consultants to build steady visibility, and it's far more sustainable than daily posting, which is where most people burn out and quietly stop after six weeks.

Is it okay to repost the same idea on LinkedIn more than once?

Yes, and you probably should. Most of your audience never saw the first version, LinkedIn's typical organic reach for a single post reaches only a small slice of your followers, so reworking a strong idea with a new angle or opening line months later is not lazy, it's just realistic about how the platform works.

Where do I find LinkedIn content ideas if I have no clients or audience yet?

Read comment sections on posts in your industry with 50 plus comments and note the repeated questions, join relevant Facebook groups where people ask raw, unpolished questions, and write down every question you've been asked in job interviews, networking chats or DMs, since those are exactly the questions your future audience will have too.

Should I use AI tools to generate LinkedIn post ideas?

They're fine for breaking a blank-page moment, but AI-generated ideas tend to sound like everyone else's AI-generated ideas because they're pulling from the same patterns. Your inbox, your client calls and your own analytics will always give you sharper, more specific ideas than a generic prompt ever will.
