Does long-form content still matter in the age of AI?

If someone handed me a quid every time I heard or read “nobody reads long-form content anymore”, then there’s a chance I’d enjoying my sweet retirement right about now. In a landscape once dominated by bloggers and in-depth guides, this is now one of those lines that gets repeated so often in marketing meetings, that we’ve stopped questioning whether or not it’s actually true.

I’m not surprised when I hear this point anymore because, on the surface, it makes perfect sense. AI overviews and chatbots can answer most of our questions in a couple of lines, our attention spans are practically non-existent, and short-form video content eats into the internet’s spare time. So why-oh-why would anyone sit down and write – or read – 2,000 words on a topic, when with just a few taps, we can get the answer in seconds?

But here’s the thing: long-form content isn’t dead, or even remotely close to dying.

What’s dying is that age-old notion that long-form content should exist purely to hit a word count – content that was written for search engines rather than people, padded out with fluff, and actually saying very little by the time you reach the conclusion. But that’s a completely different problem, and it’s one that existed long before AI stepped onto the playing field.

So what’s actually changed?

AI, of course, is the change, and what that’s done is allowed people to get quick answers to their queries. If someone wants to know how old someone is, the capital of a country, or cups to grams measurement conversion, they’re not going to be heading over to a 3,000-word article to find out. And they never really needed to.

What AI hasn’t changed is the WHY brands need to publish in-depth content in the first place. This type of content has never really been about answering quick, transactional queries – it’s about building topical authority, earning trust, and giving search engines (and now LLMs) enough substance to recognise you as a credible source on a subject. None of that happens in 200 words.

Why long-form still matters – maybe more so than ever

If you’re a brand that thinks “AI will just summarise it anyway” – then you’re missing the point entirely. LLMs need something to pull from and summarise – and as much as they would like to – they can’t just pull answers out of thin air, because AI works by synthesising content from sources they trust. And depth is still one of the strongest trust signals out there.

A genuinely in-depth piece can:

• Give search engines and LLMs more context to pull from and cite
• Build topical authority around the subjects you actually want to be known for
• Provide the substance that makes a page worth linking to (which can make the life of your Digital PR team a hell of a lot easier)
• Get repurposed into multiple short assets like social posts, email content, sales collateral – rather than the other way around
• Answer the follow-up questions and objections that a quick answer never gets close to
• Demonstrate actual expertise, rather than just claiming it in an “About Us” page

Short-form content certainly has its place; it’s brilliant for capturing attention and driving those quick bursts of engagement. But it was never designed to carry the weight of building authority on its own – and that hasn’t changed simply because AI has come out to play.

What types of long-form content are worth your time?

Not all types of long-form content is created equal, and lumping all of them together is part of why the “is it still worth it?” question keeps cropping up.

In-depth guides

The classic. A genuinely useful, comprehensive guide on a topic your audience cares about does more heavy lifting than ten thin blog posts combined. The key word here is useful – if it doesn’t actually help anyone do or understand something, it’s not a guide, it’s just a long page.

Original research and data

This is where long-form earns its keep twice over. A well-researched, data-led piece gives you something unique to publish and something newsworthy to pitch to journalists. It’s hard to fake, which is exactly why it carries weight with people and with search engines.

Thought leadership

Less about campaigns, more about consistently sharing genuine opinions, predictions, and insight. This is where a brand (or the person behind it) starts to feel like an actual authority rather than just another website that exists.

Case studies and comparisons

These tend to get overlooked, but they’re some of the most useful long-form content you can produce – particularly now that people (and AI tools) are pulling together “best of” style recommendations. Detail and specificity win here, not vague claims.

Where AI actually fits into all this

AI tools are genuinely useful for research, structuring, and speeding up the first draft of long-form content. There’s no point pretending otherwise. But the bit that actually makes a piece worth publishing – original opinion, real expertise, the lived experience of having actually done the thing you’re writing about – still has to come from a person.

And ironically, that’s exactly why long-form matters more in an AI-saturated world, not less. When anyone can generate a generic 800-word article in thirty seconds, the brands that stand out are the ones still willing to go deeper, add something genuinely useful, and put real expertise behind what they publish. Thin content was always replaceable. Good long-form content never was – AI has just made that gap more obvious.

So, does long-form still matter?

Absolutely! Just maybe not in the way it used to.

Long-form content was never really about word count – or at least it shouldn’t have been – and it certainly shouldn’t be treated that way now either. It’s about giving your audience – and increasingly, the AI tools they’re using to find you – a genuine reason to trust what you’re saying. The brands writing long-form content purely to satisfy an SEO checklist were always on borrowed time. The ones using it to genuinely demonstrate expertise? They’re the ones AI is going to keep pointing people towards.
