SEO vs AEO vs AIO: why your SMB needs all three in 2026

Google still drives traffic. But ChatGPT, Claude, and Perplexity now answer the question before users click. Your site needs to rank AND get cited. Here's the three-axis model we use at gohexa to score every site we audit.

Three years ago, "SEO" was a complete checklist for web visibility. Get your title tags right, build backlinks, ship a sitemap, monitor Search Console. Done.

In 2026, that checklist still matters, but it's no longer sufficient.

Here's what changed: when someone searches "best italian restaurant in munich" today, they don't always click through to a website. They ask ChatGPT, Claude, or Perplexity. The answer engine reads the web, synthesizes results, and gives them a curated three-line answer with citations. If your business isn't structured for those engines to quote you, you're invisible, even if you rank #2 on Google.

That's why we score every site we audit on three axes, not one.

SEO: still the foundation

Search Engine Optimization is what you already know. Google's crawler indexes your HTML. Ranking signals: relevant title tags, meta descriptions, proper heading hierarchy, alt-text on images, mobile-responsive design, fast Core Web Vitals, valid sitemaps, working robots.txt, HTTPS, and, for local businesses, LocalBusiness schema with consistent NAP (Name, Address, Phone) across the web.

SEO drives roughly 60% of the traffic for most SMB sites in our cohort. Cutting it costs you. Doing it well costs less than you'd think. It's mostly mechanical hygiene plus content.

AEO: how ChatGPT cites you

Answer Engine Optimization is newer and more interesting. When an LLM answers a question, it does one of three things:

  1. Quotes a website directly (with a citation link)
  2. Synthesizes from many sources (and may name some)
  3. Hallucinates an answer (and names no one)

You want to be in category 1. To get there:

  • Write factual content. Specific facts ("We've operated since 1987 in Munich's Glockenbachviertel") are quotable. Marketing fluff ("the best Italian experience in town") is not.
  • FAQ pages with Q&A schema. LLMs love structured Q&A. If your page literally has "Q: What hours are you open? A: …" with the schema markup, you'll be the cited source.
  • Clear business summary above the fold. The first 200 words of your homepage should tell an LLM exactly what you do, who you serve, and where.
  • /llms.txt: a new convention. A plaintext file at the root of your site that gives LLM crawlers a curated summary. Few sites have one. Adding one is a small win.

AIO: the structured data layer

AI-readable structured data is the deepest axis. It's about whether your site can be machine-read at all.

  • JSON-LD coverage. Every page should embed at least one structured-data block (LocalBusiness, FAQPage, Service, Product, Article). Most SMB sites we audit have zero. Adding correct JSON-LD can raise an audit score 20+ points.
  • Semantic HTML. <main>, <article>, <header>, <nav>, <section>, <aside>, not endless <div> soup. LLM crawlers (and accessibility tools) use semantic tags to understand page structure.
  • Content chunkability. Your content should split cleanly into ~200-token chunks for embedding indexes. Long unbroken paragraphs hurt. Subheadings every 200-300 words help.

The three-axis scorecard

When we audit a site, we score each axis 0-100 and surface 3-5 specific findings per axis with severity (high / medium / low) and a fix hint. Most SMB sites we see land in the 30-50 range across all three, meaning a single careful rebuild can move them into the 80+ range and unlock both Google rankings AND LLM citations.

The audit is free. Paste your URL at gohexa.ai/audit and you'll get the same scorecard within 60 seconds.

If the score is low and you want help fixing it, that's what we do: bespoke website builds from €2-5k, scoring in the green on all three axes from day one, plus optional monthly maintenance.

The web didn't stop being important when ChatGPT arrived. It just got a second audience.
