Start with SEO if your website is not yet solid, add AEO if you rank but get few answer-box and AI Overview appearances, and add GEO if buyers are asking ChatGPT or Perplexity and your brand never shows up. You do not need three separate projects. The three share one foundation of clear, accurate, well-structured content on a healthy site.
The three terms in plain English
SEO, AEO and GEO are three ways of being found. They overlap far more than the acronyms suggest, but each one aims at a different result, so it helps to know which result you want first.
SEO (search engine optimization) gets your pages to rank in Google and Bing so people click through. AEO (answer engine optimization) structures your content so search engines can lift a direct answer from it, as in featured snippets, People Also Ask boxes and Google’s AI Overviews. GEO (generative engine optimization) aims to get your brand mentioned and cited inside answers written by tools like ChatGPT, Perplexity, Gemini and Google’s AI Mode. These definitions follow the guides from LLM Pulse and Digital Agency Network.
If you would rather have someone audit all three for your site, our SEO, AEO and GEO services start with a free visibility audit.
SEO vs AEO vs GEO side by side
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank and earn the click | Be the source of the direct answer | Be mentioned and cited in AI-written answers |
| Where it shows | Blue links, local pack, shopping listings | Featured snippets, People Also Ask, AI Overviews | ChatGPT, Perplexity, Gemini, AI Mode |
| What moves it | Technical health, content depth, backlinks | Clear answer blocks, accurate facts, valid structured data where it fits | Brand presence on other sites, reviews, directories, fresh facts |
| How you measure it | Clicks, impressions, position, conversions | Snippet share, AI Overview citations | Mention rate and citation share across a set of prompts |
| Typical first step | Fix the site and the money pages | Rewrite key pages to open with a 40 to 60 word answer | Test 20 to 50 buyer prompts and find the gaps |
Metrics and first steps summarize the LLM Pulse and Digital Agency Network guides. Treat them as a working checklist, not a guarantee of results.
Why you do not need three separate projects
The most useful point in the current guides is how much the three share. LLM Pulse describes the centre of the overlap as well-structured, factually accurate, authoritative content with strong technical hygiene, and estimates that a page that performs well there covers roughly 80 percent of AEO and GEO work, leaving about 20 percent for specialist layers. Digital Agency Network makes the same point from the other side: technical SEO is the floor, and most AEO improvements also help traditional rankings.
That is why we treat them as one system rather than three add-ons. Our case studies show the work as it is delivered.
Which one should you start with?
Digital Agency Network ranks a primary and secondary focus for common situations. We have kept its picks and added a plain-English note.
| Your situation | Start with | Then add | Why |
|---|---|---|---|
| Local service business | SEO | AEO | Customers search a service plus a place, so maps, reviews and service pages come first |
| E-commerce product pages | SEO | AEO | Product and category pages win on search intent and listings |
| New website | SEO | AEO | You need crawlable pages and authority before anything else works |
| “How do I” and “what is” content | AEO | SEO | These questions are the ones answer boxes and AI Overviews serve |
| B2B SaaS with a long evaluation | GEO | SEO | Buyers research with AI tools and compare vendors before they visit your site |
| Brand reputation and comparisons | GEO | AEO | What AI tools say about you depends on what other sites say about you |

A simple way to find your biggest gap
Both guides give the same diagnostic, and you can run it in a week without any new tools.
- Weak technical health or little authority: start with SEO. Nothing else works if search engines and AI systems cannot reach and trust your pages.
- Rankings are fine but traffic is sliding: the gap is likely AEO. Answers are being taken at the top of the results page, so make your pages the ones that get quoted.
- Strong rankings and snippets but no mention in ChatGPT or Perplexity: the gap is likely GEO. Work on how you appear on directories, review sites and other pages that AI tools read.
LLM Pulse suggests checking AI Overview presence for your top 50 keywords and tracking 20 to 50 representative prompts across ChatGPT, Perplexity and Gemini, then prioritizing the largest gap.
What changes for GEO versus SEO
GEO is where most businesses are behind, because it depends on pages you do not own. WRITER cites research that about 85 percent of brand mentions in AI search come from third-party pages rather than brand-owned sites. If that holds for your market, reviews, directories and comparison articles matter as much as your own blog.
It is also worth knowing what you do not need. WRITER reports that Google’s May 2026 AI search guide says structured data is not required for AI Overviews or AI Mode, and that no special schema is needed. LLM Pulse adds that the crawlers differ by product: Googlebot for Google Search AI features, OAI-SearchBot for ChatGPT search and PerplexityBot for Perplexity, while GPTBot and Google-Extended control other uses. We explain the ChatGPT side in our post on how ChatGPT search finds new pages, and the Google side in how links are changing in AI Mode.
Common mistakes to avoid
- Treating SEO as dead. LLM Pulse lists this as a pitfall because SEO still drives most organic traffic for many businesses.
- Optimizing only for Google snippets. ChatGPT and Perplexity do not rely on Google’s AI Overviews.
- Waiting on GEO. LLM Pulse argues early citations compound as models update.
- Hiring three teams. The work is largely shared, so one plan and one monthly dashboard is simpler and cheaper. Our guide to what SEO costs in 2026 shows how AEO and GEO are priced on top.
The bottom line
Pick your starting point from the table, fix the foundation first, and add answer and citation work in the order your gap shows. Most established businesses will find they are strong in one area and thin in another, which is a better position than starting from nothing.

Frequently Asked Questions
Do I need AEO and GEO if I already do SEO?
Probably a little of each, but not as separate projects. LLM Pulse estimates a page that performs well on the shared foundation handles roughly 80 percent of AEO and GEO work, leaving about 20 percent for specialist layers. Start by auditing where you are losing visibility, then close the biggest gap first.
Is SEO dead because of AI search?
No. LLM Pulse lists treating SEO as dead as a common pitfall, because SEO still drives most organic traffic for many businesses. Technical health, useful content and authority are also the base that AEO and GEO build on. Keep that foundation strong, then add answer and citation work on top.
Do I need special schema markup for AI search?
Not according to Google. WRITER reports that Google’s May 2026 AI search guide says structured data is not required for AI Overviews or AI Mode, and that no special schema is needed. Add structured data where it matches the visible page and its type, such as products or local business details, not as an AI shortcut.
How do I know if I am visible in ChatGPT or Perplexity?
Test it directly. LLM Pulse suggests tracking 20 to 50 representative prompts across ChatGPT, Perplexity and Gemini, and checking AI Overview presence for your top 50 keywords. Record whether your brand is mentioned or cited each week, and review the full set monthly. Patterns matter more than any single answer.
Which should a local service business start with?
SEO. Digital Agency Network lists local business visibility as an SEO-first situation with AEO second. Get your Google Business Profile, service pages and reviews right, then add clear question-and-answer content for the questions customers ask before calling. Budget is better spent on that foundation than on chasing AI citations first.
