Search is not what it used to be. Just five years ago, Google’s main job was matching your keywords to web pages. Today, Large Language Models (LLMs) like ChatGPT and Google’s AI Overviews are changing how people find answers. Your business needs to understand what this means for your website.
The shift is real. People are getting answers directly from AI now. They are not always clicking through to websites anymore. This sounds scary, but here is the truth: the businesses winning in this new landscape are the ones with solid technical SEO (search engine optimisation) foundations. Everything else depends on it.
What Are LLMs Doing to Search?
LLMs are trained on vast amounts of text from across the internet. When someone asks a question, these models generate answers instantly. They pull information from multiple sources and present it in one place.
Google has noticed. They are now showing AI Overviews in search results. These summaries appear at the top, generated by Google’s LLM technology. The result? Users get quick answers without leaving Google’s page.
This is not necessarily bad for your business. But it does mean one thing: if your website is not technically sound, search engines will not rank it. If they cannot crawl it, cannot index it, and cannot understand it, your content might as well not exist.
Why Technical SEO Is Your Real Competitor Advantage Now
Think of technical SEO like the engine of your car. You can have the shiniest paint job and the most comfortable seats. But if your engine does not start, nobody goes anywhere.
LLMs have made this foundation even more critical. Here is why:
Site Speed and Core Web Vitals
LLMs are hungry for data. Google’s algorithms now look at how fast your pages load. They measure three core metrics: how quickly the page becomes interactive, how stable the layout is, and how responsive it feels to user input.
South Africa faces unique challenges here. Load shedding affects internet infrastructure. Data costs are real. Your site needs to load fast on slow connections.
A slow site loses visitors. Studies show that three-second delays cause visitors to leave. When people bounce, Google sees it. Rankings drop. LLMs then have less fresh content from your site to learn from.
Mobile-Friendliness Is Non-Negotiable
Most South Africans browse on mobile. If your site is not mobile-friendly, you have already lost the game.
LLMs work with Google’s mobile-first indexing. Google primarily uses the mobile version of your site to understand and rank it. A site that works beautifully on desktop but falls apart on a phone will never rank well.
This is not a nice-to-have. This is your baseline requirement.
Crawlability and Indexing
Imagine a taxi rank where the marshals cannot find passengers because the signs are broken. That is what happens when Google cannot crawl your site.
If your website has broken links, missing sitemaps, or pages blocked from search engines, Google simply cannot access your content. If Google cannot find it, AI models cannot learn from it. Your business becomes invisible to LLMs.
Your technical setup needs to:
- Have a working robots.txt file that welcomes search engines
- Include an XML sitemap so Google knows all your pages exist
- Avoid blocking important pages with noindex tags by mistake
- Fix broken internal links regularly
Structured Data and Schema Markup
This is how you tell search engines what your content actually means.
Schema markup is like labelling items in a cupboard. If you just put tins on a shelf with no labels, someone might grab the beans when they wanted the tomatoes. With clear labels, anyone finds exactly what they need.
When you add structured data to your site, you help LLMs understand your business better. You tell Google: “This is my business address.” “This is my opening hours.” “These are my product prices.” “This is what my customers think.”
Google uses this data to populate rich snippets in search results. LLMs use it to provide more accurate answers. Your business becomes more visible and trustworthy.
HTTPS and Site Security
Trust is everything, especially online. HTTPS encrypts data between your visitor’s browser and your server. It tells people their information is safe.
Google ranks HTTPS sites higher than HTTP sites. More importantly, people trust sites with the padlock icon. When LLMs recommend sources, they favour secure websites.
If your site still runs on HTTP, switch now. It is not optional anymore.
The Real Problem: Most Businesses Skip the Basics
We see this constantly. Business owners invest thousands in content marketing. They build backlinks. They try every new tactic.
But their site is slow. It breaks on mobile. Google cannot crawl half their pages. The structured data is missing.
It is like decorating a house while the foundation is cracking. You can rearrange the furniture all you want. The house is still collapsing.
With LLMs in the picture, this problem is worse. LLMs learn from what Google can access and understand. A poorly configured site limits what LLMs learn about your business. This limits how often they recommend you.
What You Should Do Right Now
Start with an audit. You need to know where you stand.
Check your site speed using Google’s PageSpeed Insights tool. Aim for green scores across all Core Web Vitals. If you score poorly, talk to your web developer. Optimise images. Reduce code bloat. Enable caching.
Test your site on mobile. Open it on an iPhone and an Android phone. Can you navigate easily? Can you read the text? Can you click buttons without accidentally hitting something else?
Check your crawlability. Use Google Search Console to see if Google can access your pages. Look for crawl errors. Fix broken links. Create a sitemap if you do not have one.
Add schema markup. Start with basic business information. Add product data if you sell things. Add review schema if customers leave feedback.
Make sure your site runs on HTTPS. If you still use HTTP, this should be your first priority.
LLMs Are Not the Enemy
LLMs are tools. They are not replacing Google. Instead, they are changing how Google delivers results.
This is actually good news for businesses that get the basics right. A technically sound website becomes even more valuable. Search engines and AI models can understand it better. Your content ranks higher. Your business gets more visibility.
The businesses struggling are the ones that ignored technical SEO. Now their sites are falling behind.
You do not have to be one of them. Start with the foundation. Build on it. Everything else becomes easier.
Your future customers are searching right now. Make sure your site is ready to be found.
