What's different about websites in the AI era? SEO, AEO and GEO explained

Customers used to find suppliers by opening Google, typing a keyword and scrolling through page after page of results. Now there are more ways to look. Google results open with an AI Overview at the top, and many people stop reading right 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 hasn't 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 hand 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 it cites or recommends you in the answer it generates.

The three sound like three separate jobs, but they're really one foundation with two extensions. Get the site's technical structure right and you have SEO, and you've already cleared most of the bar for AEO and GEO as well. What's left 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 has to do, and what the content has to do.

What the system has to do

  1. The content is actually in the page source. Some sites look beautiful, but their source code is empty; the content only shows up once the browser has run the scripts. Google can just about cope with that. Most AI crawlers simply give up.
  2. 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 keep going.
  3. 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 lean heavily on this.
  4. Sitemap, RSS and robots.txt set up correctly, and not locking AI crawlers out. Many sites have a robots.txt set up years ago that blocks GPTBot, ClaudeBot and similar crawlers by default, and the owner never knew.
  5. 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.
  6. Multilingual and URL conventions. The 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.
  7. Alt text on images, and fast loading. These are basics, but plenty of sites skip them.

What the content has to do

  1. Answer questions directly. One point per paragraph, question first, answer right after. AI Overviews love to cite paragraphs like that.
  2. Show the date. Who wrote it, when it was written, and when it was last updated. This affects whether AI judges the content trustworthy.
  3. Talk about things you've actually done. Cases, numbers and methods beat adjectives. When AI decides whom to cite, it looks for concrete information.
  4. Keep updating. A single article can keep getting cited for a long time, but a site that hasn't been touched in a year slowly loses both rankings and citations.

Our website system already does all of this

Websites built by Bright Forever Digital meet all seven of the "system" requirements above from the day they launch, with no extra work, no add-ons and no plugins:

  • Every page is fully rendered 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, which gives Google the chance 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's 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've built up aren't reset.
  • Images are served through a global content delivery network, and alt text can be filled in centrally in the media library.

For how the same requirements get covered on WordPress, and how many plugins it takes, WordPress or an AI website system? goes through them one by one. 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 went in the right place afterward.

On the right structure, every article goes further

Writing an article on a laptop

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 shot at being found in search, cited in AI Overviews, and recommended by AI.

We've seen plenty of clients pour 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.

FAQ

My site already has SEO. Do I still need to worry about AEO and GEO?
Check two things first: whether your robots.txt blocks AI crawlers, and whether your content can be read in the page source. If both are fine, you already have the foundation for AEO and GEO, and what's left is adjusting how the content is written.
How long until these changes show results?
Google usually indexes new pages within a few days to a few weeks, and rankings take two to three months to settle. There's no fixed timeline for AI citations, but the prerequisites are the same: get indexed first, and make the content concrete.
If we move an old site over, will we lose our rankings?
As long as the redirects from the old URLs to the new ones are set up properly, the rankings move with the site. It's something we always take care of when migrating a site.
How is Bright Forever Digital's SEO article writing priced?
It's quoted per project. Note the topics or industry you want to cover when you fill out the form, and we'll go through it with you during the consultation.
