If you're a marketing manager at a building product manufacturer, you've probably noticed the acronyms piling up. SEO vs GEO vs AEO is now a regular question in boardrooms, and most of the answers online are written for retailers or SaaS firms, not for a business with 400 products, a technical specification and a specifier who needs the right data fast.
Here's the short version. Most of the work is the same. The labels matter less than the foundations. Below, we define each term in plain English, show where they overlap, and suggest an order of priorities for a manufacturer with a large range.
SEO (search engine optimisation) is making your site easy for Google and Bing to find, understand and rank. A contractor searches "A1 non-combustible insulation board" and your product page appears in the results. The goal is a click.
AEO (answer engine optimisation) is about being the direct answer. Think of the snippet at the top of Google, the "People also ask" box, or a voice assistant reading out a reply. A specifier asks, "What is the U-value of 150mm PIR board?" and your page supplies the figure in a clear sentence.
GEO (generative engine optimisation) is about being mentioned or cited when AI tools such as ChatGPT, Perplexity, Gemini or Copilot write an answer. Someone asks, "Which manufacturers make BBA-certified breathable membranes?" and your brand is named in the response. The user may never visit your site.
LLM optimisation, sometimes called LLM SEO, is the broader habit of making your content easy for large language models to read, trust and quote. In practice it sits very close to GEO. Treat the two as near-synonyms.
When people compare SEO vs GEO, they tend to imagine two separate disciplines. They aren't. AI tools draw on much of the same material that search engines do: your website, your documentation and what others say about you.
The shared foundations are:
If you do these well, you've done most of the work for all of the acronyms.
The differences are real, but they are differences of emphasis.
AEO vs SEO. SEO asks, "Can we rank for this topic?" AEO asks, "Can we answer this exact question in two clear sentences?" That means writing a short, direct answer near the top of the page, then adding the detail below. A page on cavity barriers might open with: "Cavity barriers slow the spread of fire and smoke through concealed cavities. Required locations are set out in Approved Document B." Then it goes deeper.
GEO vs AEO. AEO usually still ends in a visible answer on a results page, often with a link. GEO is about being included in a synthesised answer, where sources may be mentioned briefly or not at all. Because of that, GEO leans harder on reputation beyond your own site. If your brand is described consistently and favourably across trade directories, press and partner pages, AI tools have more to draw on.
GEO vs SEO. SEO success is measured in rankings, traffic and enquiries. GEO success is harder to measure. You're looking at whether your brand appears in AI answers, and whether the description is accurate.
One caution. No one outside the platforms knows exactly how AI tools choose their sources, and the behaviour changes often. Be wary of anyone selling secret tactics. Clear, credible, well-structured content is the safest bet.
If you have hundreds of SKUs, you can't do everything at once. This is the order we'd work in.
1. Fix the foundations. Check that product pages are indexable, load quickly and hold their key data as readable text, not just in downloadable PDFs. If your site is holding you back, this may be a case for a website redesign or a rebuild using Webflow, where clean structure and fast pages are easier to maintain.
2. Standardise your product page template. Every page should carry the same blocks: a short description, a specification table, standards and certifications, applications, installation notes, compatible products and FAQs. Consistency helps people and machines alike.
3. Answer the questions specifiers really ask. Start with your top ten product categories. List the 10 to 20 questions your technical team hears most often. Write short, direct answers, then link to the detail. This is your AEO work.
4. Add structured data. Product, FAQ, organisation and breadcrumb markup helps search engines and AI tools interpret your pages correctly.
5. Build your reputation off-site. Keep your NBS listing, BIM objects, certificates and distributor pages accurate. Pursue trade press features and case studies with named project outcomes. This is where your GEO and LLM optimisation efforts will pay off most.
6. Check what AI tools say about you. Once a quarter, ask ChatGPT, Gemini and Perplexity the questions your customers ask. Note whether you appear, whether the facts are right, and which sources they cite. Then fix gaps at the source.
What not to do: don't build a separate "AI site", don't rewrite every page in one go, and don't drop SEO because a new acronym is trending.
You don't need three strategies. You need one well-built website, clear technical content and a solid reputation, and then a bit of extra care on how answers are written and how your brand is described elsewhere.
