The way websites are discovered is changing. For many years we focused mainly on Google crawling pages and ranking links. Today, websites also need to be understandable to AI search systems and Large Language Models (LLMs).
Two areas that are becoming increasingly important are:
- Structured data (Schema markup)
- Allowing legitimate AI/LLM crawlers to access your content
They are not magic ranking buttons, but they help search engines and AI systems understand what your website is about. 🤖
1. What Is Schema Markup?
Schema is extra information added behind your website pages that helps machines understand your content.
A human sees:
David Can’t Swim provides SEO advice in Plymouth.
A search engine can understand:
- this is a person
- this person is an SEO professional
- this website covers SEO
- the business operates in Plymouth
- articles have authors and dates
Schema is like adding labels to boxes in a warehouse. The contents were already there, but now the machines know exactly what each box contains.
2. Important Schema Types for Local Businesses
LocalBusiness Schema
Useful for:
- tradespeople
- shops
- restaurants
- agencies

Helps define:
- business name

- author identity
- expertise
- website ownership
- social profiles
This supports trust signals.
Article Schema
For blogs and news-style websites.
Helps identify:
- headline
- author
- publishing date
- modified date
- article type
FAQ Schema
Useful when your page genuinely answers questions.
Example:
“How much does SEO cost in Plymouth?”
“How long does SEO take?”
Good FAQ sections also improve user experience.
3. Does Schema Directly Improve Rankings?
This is where many SEO articles exaggerate.
Schema itself is not usually a magic ranking factor.
However, it can improve:
✅ Search understanding
✅ Rich results eligibility
✅ Content interpretation
✅ AI understanding
✅ Trust signals
Think of Schema as improving communication between your website and machines.
4. Should You Allow LLM Bots to Crawl Your Website?
This is becoming an important conversation.
AI companies use crawlers to discover publicly available information.
Examples include:
- search engine AI features
- AI assistants
- answer engines
If you block every AI crawler, you may reduce the chance of your content being discovered or used in some AI-powered search experiences.
However, website owners should make their own choice.
5. The Important Balance
A sensible approach is:
✅ Allow reputable search and AI crawlers
✅ Keep your important content accessible
✅ Avoid blocking everything automatically
✅ Monitor server activity
✅ Protect private areas
Your public blog, guides and knowledge articles are usually the content you want discovered.
Your:
- customer database
- private documents
- admin areas
- paid content
should remain protected.
6. The New SEO File: llms.txt
Many people are discussing llms.txt.
The idea is similar to robots.txt, but designed to provide AI systems with a clear guide to important website information.
It can potentially highlight:
- key pages
- documentation
- important resources
- preferred content
The SEO industry is still debating exactly how widely it will be adopted, but it shows where the internet is moving:
From websites being indexed to websites being understood.
7. WordPress: Easy Ways To Improve LLM Readiness
For a WordPress website:
✅ Use clean headings
✅ Write helpful articles
✅ Add author information
✅ Use Schema plugins
✅ Keep URLs simple
✅ Create clear category structures
✅ Add internal links
✅ Keep pages fast
Popular SEO tools can handle much of the technical Schema work automatically.
8. The Biggest Hidden Advantage: Clear Information Architecture
A messy website confuses humans and machines.
A simple structure works well:
Home
↓
Services
↓
Location Pages
↓
Helpful Guides
↓
FAQs
This creates a little knowledge map that both Google and AI systems can follow.
Final Thoughts
The future of SEO is not about gaming algorithms.
It is about making your website:
- easy to crawl
- easy to understand
- trustworthy
- useful
Schema tells machines what your content means.
Good website structure tells them why it matters.
Allowing trusted AI crawlers gives your content a chance to appear in the growing world of AI-powered search.
The websites that win in the future will not necessarily be the biggest. They will be the ones that are the clearest. 🌱
