Customers used to find suppliers by opening Google, typing a keyword and scrolling through page after page. Now there are more ways to look. Google results open with an AI Overview at the top, and many people stop reading there. Others ask ChatGPT or Gemini directly, "Which pediatric clinics in Nantou would you recommend?", get three names back, and choose from those three.
The website's job has not changed: it still has to help the right people find you. What has changed is that "finding" now has several entry points, and each one reads a website a little differently. SEO, AEO and GEO are simply the names for those three entry points.
Three terms, explained once
SEO, search engine optimization. Making sure Google can find your website, understand what each page is about, and rank you near the top when someone searches for a related keyword. This is the oldest and most basic layer; the other two are built on top of it.
AEO, answer engine optimization. Some places skip the list of links and give you an answer directly: the AI Overview at the top of Google results, featured snippets, and answer tools like Perplexity. AEO is about getting your content used as that answer, with your website credited as the source.
GEO, generative engine optimization. When AI assistants like ChatGPT, Gemini and Claude answer a question, they read websites, digest them and generate a response. GEO is about making sure the AI can read your site and understand what you do, so that it cites or recommends you in the answer it generates.
The three terms sound like three separate jobs, but they are really one foundation with two extensions. Get the site's technical structure right and you have SEO, and you have already cleared most of the bar for AEO and GEO as well. What remains is how the content is written.
What a website needs to deliver all three
We split the requirements into two groups: what the website system itself must do, and what the content must do.
What the system must do
- The content is actually in the page source. Some sites look beautiful, but their source code is empty; the content only appears once the browser has run the scripts. Google can just about read that; most AI crawlers simply give up.
- Every page has its own title, description and a clear heading hierarchy. Search engines and AI both read the title first before deciding whether to read on.
- Structured data. A machine-readable format that states whether a page is a company, an article, a set of questions and answers, or a step-by-step guide. AI Overviews and featured snippets rely heavily on this.
- Sitemap, RSS and robots.txt set up correctly, and not shutting AI crawlers out. Many sites have a robots.txt set up years ago that blocks GPTBot, ClaudeBot and similar crawlers by default, without the owner ever knowing.
- A site description written for AI. This is llms.txt, a plain-text file in the site root that tells AI what the site is, which pages it has, and how it can be cited.
- Multilingual and URL conventions. Chinese and English versions point to each other, each piece of content has exactly one canonical URL, and when a URL changes, the old one redirects automatically.
- Alt text on images, and fast loading. These are basics, but many sites skip them.
What the content must do
- Answer questions directly. One point per paragraph, with the question first and the answer right after. AI Overviews love to cite paragraphs like this.
- Show the date. Who wrote it, when it was written, and when it was last updated. This affects whether AI judges the content trustworthy.
- Talk about things you have actually done. Cases, numbers and methods beat adjectives. When AI decides whom to cite, it looks for concrete information.
- Keep updating. A single article can keep being cited for a long time, but a site that has not been touched in a year slowly loses both rankings and citations.
Our website system already does all of this
Websites built by Bright Forever meet all seven of the "system" requirements above from the moment they launch, with no extra work, no add-ons and no plugins:
- Every page is rendered in full by the server, so search engines and AI crawlers can read it the moment they open it, without waiting for scripts to run.
- Every page automatically carries its canonical URL, links to its other language versions, and the title and image used for social sharing.
- Structured data is generated site-wide: website and organization information on every page, plus article information and breadcrumbs on article pages. FAQ sections, key takeaways and step-by-step guides inside articles are automatically turned into the matching structured data, giving Google the opportunity to show question-and-answer results.
- The sitemap, RSS and llms.txt are generated automatically and updated every time a new article is published; there is nothing to maintain by hand.
- robots.txt is open to Google and the major AI crawlers by default, while admin panel pages are automatically excluded from indexing.
- When an article's URL changes, the old URL redirects to the new one with a 301, so the rankings you have built up are not reset.
- Images are served through a global content delivery network, and alt text can be filled in centrally in the media library.
This is one of the reasons we chose this system as our foundation. Across the clients we work with, more than 30 keywords rank steadily on the first page of Google, not through any special trick, but because the structure was right first and the content was put in the right place afterwards.
On the right structure, every article goes further
Structure is the foundation; content is the house built on top of it. Without a solid foundation, writing more articles is wasted effort. With one, every article has a chance to be found in search, cited in AI Overviews, and recommended by AI.
We have seen plenty of clients put real effort into dozens of articles on an old website, only for Google to index a small fraction of them and for AI to read none at all, because of structural problems in the system. Move the same content onto the right structure and it performs differently.
