GEO isn't replacing SEO. Here's why that matters.

If you have hired an SEO agency in the last five years, the brief was probably simple: rank higher, get more clicks, turn those clicks into leads.

That brief is incomplete now. Google's AI Overviews, ChatGPT, Perplexity and Copilot answer a growing share of commercial questions before anyone reaches page one. Ranking still matters. Being cited inside the answer matters at least as much. That is what GEO and AEO are actually about, once you strip out the jargon.

GEO and AEO in plain English

SEO is still about being findable and rankable in classic results: crawlable pages, clear intent match, authority, technical health.

AEO (answer engine optimisation) is about structuring content so an answer engine can lift a clean, quotable answer. Think AI Overviews, featured-style answers, and any surface that summarises rather than lists ten links.

GEO (generative engine optimisation) is about earning citations and recommendations inside generative tools such as ChatGPT and Perplexity, including when the model leans on third-party sources rather than your homepage.

Different labels, same commercial job: when a buyer asks a question, your brand should be in the answer, not only buried under it.

Why this is not "SEO is dead"

Plenty of vendors will sell you GEO as a replacement product. For most UK and US SMEs, that is the wrong pitch.

Answer engines still ground themselves in pages that already look trustworthy in search. Weak technical SEO, thin content and zero third-party mentions do not suddenly become citation-worthy because you renamed the retainer. Citation is layered on ranking and reputation. It is not a shortcut around them.

If you already invest in SEO, the practical upgrade is not "stop ranking." It is "make your best pages answer-shaped, keep them current, and earn mentions off your own site." We covered the wider citation mechanics in our piece on AI search optimisation in 2026. This article is about how GEO and AEO fit next to the SEO work you are already buying.

What UK SMEs should change first

You do not need a 40-page strategy deck. You need a short list of changes that move citations and still protect classic rankings:

• Lead with the answer. For each money page and guide, put a direct, one-to-two sentence answer under the H1 or first H2. Models extract passages. Humans skim. Both reward the same habit.
• Rewrite headings as real questions. "How much does X cost in the UK?" outperforms a vague "Our approach" every time for answer surfaces.
• Add comparison and steps where they are honest. Tables, numbered processes and FAQs are easier to lift than long narrative blocks.
• Fix Bing visibility, not only Google. ChatGPT Search and Copilot lean on Bing's index. If Bingbot is blocked or your key URLs are missing there, GEO work on-site will not show up where buyers ask.
• Invest in proof off your domain. Reviews, press, niche directories and genuine forum mentions feed generative citations. Your blog alone rarely does.
• Refresh dates and numbers. Stale stats and "last updated 2023" pages are easy for models to skip when a competitor published last month.

What to ask an agency before you buy "GEO"

If an agency pitches GEO or AEO as a bolt-on with no link to your existing SEO and content, push back. Useful questions:

• How will you restructure our top landing pages for extraction without wrecking rankings?
• How do you track citations in ChatGPT, Perplexity and Google AI surfaces month to month?
• What is the plan for third-party mentions, not only on-site blogs?
• Are schema, crawl access and Bing coverage part of the same engagement?
• How does this sit alongside paid search when AI answers suppress organic clicks? (If budget decisions are next, our guide on SEO vs paid ads for lead generation is a useful companion.)

A competent answer sounds like an extension of SEO and PR. A weak answer sounds like a new acronym and a content calendar.

A simple way to decide where to spend next

Ask one question: are buyers already finding you in classic search, or are you invisible before the AI layer even starts?

• Invisible in classic search - fix fundamentals first. Crawl, intent pages, local or national authority, conversion paths. GEO on a weak site is theatre.
• Ranking but losing clicks to AI answers - prioritise AEO-style rewrites on your highest-impression pages, add FAQ schema where it is accurate, and start a citation tracking habit.
• Ranking and sometimes cited, but rivals own the chatbot recommendations - push GEO harder via digital PR, reviews and specialist publications your buyers already trust.

Most SMEs sit in the middle bucket. That is where restructuring existing winners beats publishing twenty new AI-written posts.

Frequently asked questions

SEO is about ranking in classic search results. AEO is about being the source an answer box or AI Overview pulls from. GEO is about being cited or recommended inside tools like ChatGPT and Perplexity. All three still rely on crawlable, trustworthy content.

You need both. GEO and AEO do not replace rankings. They reward pages that already rank and that answer questions clearly enough to be quoted. Skip classic SEO and you give answer engines nothing solid to cite.

Search your brand and your top customer questions monthly in Google AI Mode or AI Overviews, ChatGPT and Perplexity. Note whether you appear, who appears instead, and which pages or third-party sources get credited.

Usually no. Treat GEO and AEO as an extension of SEO and content strategy, not a separate retainer. Ask your agency how they restructure pages for extraction, build third-party mentions, and track citations alongside rankings.
