So here’s the question keeping marketing teams up at night. Large language models (LLMs) like ChatGPT can write content fast. They understand search intent. They optimise for readability. Does that mean traditional SEO (search engine optimisation) is dead?
Short answer: No.
Long answer: It’s more interesting than that.

What LLMs Actually Do Well
LLMs are genuinely brilliant at certain things. They generate ideas in seconds. They help you understand what searchers actually want. They can create variations of content for different angles. They speed up research and planning massively.
Here’s what research shows:
Google’s own studies found that 41% of marketers now use AI tools for content creation. That number keeps climbing. LLMs excel at brainstorming, outlining, and drafting. They understand language patterns in ways that make content feel natural to humans.
For DIY business owners, this is huge. You don’t need a copywriter to create first drafts anymore. For agencies, LLMs mean your teams spend less time on repetitive writing and more time on strategy.
But here’s where things get complicated.

Where LLMs Hit a Wall
LLMs make some critical mistakes that SEO professionals catch immediately.
They hallucinate facts. An LLM might claim a statistic that sounds right but isn’t real. It sounds confident. It looks cited. It’s completely made up. Google’s algorithm punishes inaccuracy with lower rankings.
They don’t always understand search intent. Just because an LLM can write about a topic doesn’t mean it knows what someone searching for “best running shoes under £50” actually needs. Traditional SEO analysis reveals those nuances. LLMs often guess.
They miss technical SEO entirely. Keyword research, site structure, metadata, internal linking patterns, page speed optimisation, mobile responsiveness. LLMs can write about these topics. They can’t audit your website and fix them.
They create similar content at scale. Many marketers are using LLMs the same way. Google’s March 2024 update specifically targeted this problem. Generic AI-generated content now ranks worse than before.
They don’t understand context. LLMs trained on public data don’t know your local market, your competitors, or your specific audience quirks. Traditional SEO professionals do.
What Traditional SEO Still Owns
SEO specialists do things LLMs cannot.

They dig into actual data about what your competitors rank for. They study keyword difficulty and search volume. They identify gaps in your content strategy that exist nowhere in your training data. They understand the algorithm updates that change the game every few months.
SEO professionals also handle the boring but essential work. Fixing broken links. Optimising images. Improving Core Web Vitals (CWV). Building backlinks from relevant sources. These technical foundations matter more than ever.
Here’s a real example: A client approached us wanting to rank for “sustainable packaging solutions.” An LLM could write great content on that topic. But traditional SEO research revealed their audience wasn’t searching for that phrase. They were searching for “eco-friendly box alternatives” and “plastic-free packaging options.” Same topic, completely different keywords. An LLM wouldn’t find that on its own.
The Winning Strategy: The Hybrid Approach
This is where things get interesting.
The best marketers right now aren’t choosing between LLMs and traditional SEO. They’re combining them.
Here’s how it works:
Step 1: Use traditional SEO research to identify actual keywords people search for. Use tools like Ahrefs, SEMrush, or even Google Search Console. Find the gaps in your competitor’s content.
Step 2: Brief an LLM with that research. Give it the keyword, the search intent, the target audience, and your angle. Don’t just ask it to “write an article about X.”
Step 3: The LLM generates a first draft. Fast. Good enough to edit. Saves weeks of writing time.
Step 4: A human editor (ideally someone who understands SEO) rewrites sections. Adds original insights. Removes hallucinations. Verifies facts. Improves the angle.
Step 5: A technical SEO specialist optimises metadata, internal links, and formatting. They make sure the content actually ranks.
The result? Content that’s faster to produce, genuinely useful, accurate, and optimised for search.
What Agencies Need to Know
If you’re evaluating an agency’s approach to SEO in 2024, listen for this language:
They should talk about “combining AI efficiency with human expertise.” Not replacing one with the other.
They should show you their research process. How do they identify keywords? How do they validate search intent? How do they spot gaps competitors miss?
They should explain their editing and fact-checking process. If an agency is just publishing raw LLM output, run.
They should discuss technical SEO specifically. Content strategy alone doesn’t win rankings anymore. The whole package matters.
Agencies that understand this aren’t worried about LLMs replacing them. They’re excited about what LLMs let them do better.
What This Means for DIY Marketers
If you’re running a small business and can’t afford an agency, LLMs are genuinely useful.
Start here:
Use an LLM to research. Ask it questions about your industry. What are common questions customers ask? What misconceptions exist? What solutions work best? This helps you think like an SEO specialist.
Do basic keyword research yourself. Tools like Google’s free Keyword Planner or Ubersuggest’s free version show you what people actually search for. Spend an hour on this. It changes everything.
Write with intention. Use an LLM as your writing assistant, not your writer. You provide the expertise and angle. It handles the rough draft. You refine it.
Learn about technical SEO basics. Your LLM won’t handle meta descriptions, headers, or image alt text. You need to. Spend one afternoon learning these basics. It matters.
Track what actually works. Use Google Analytics and Google Search Console. See which content actually drives traffic. Learn from what works. Adjust what doesn’t.
The best DIY approach combines LLM efficiency with smart fundamentals.
The Future Isn’t Either/Or
Here’s what’s actually happening:
Google’s algorithm is getting smarter at spotting generic AI content. That means the future belongs to content that combines AI efficiency with human insight and technical precision. Pure AI content will keep ranking worse. Pure human content without technical optimisation will still get buried. The hybrid wins.
LLMs won’t replace traditional SEO. But they’re changing what SEO specialists actually do. Instead of writing hundreds of articles, they’re focusing on strategy, research, and technical implementation. That’s actually better work.
For businesses, this is good news. You can get better content faster and cheaper than five years ago. But you still need someone who understands how Google actually works.
Key Takeaways
- LLMs generate content faster but often miss accuracy and search intent nuances.
- Traditional SEO research, technical optimisation, and strategy still determine rankings.
- The winning approach combines LLM efficiency with human expertise and technical SEO knowledge.
- Generic AI content now ranks worse after recent algorithm updates.
- The future of SEO is hybrid, not either/or.
