SEO gets you ranked on Google's results; AI-SEO (GEO) gets your business named inside ChatGPT, Gemini, Perplexity and Google AI Overviews. In 2026 you need both — classic SEO for search traffic, GEO for the fast-growing audience that asks AI for recommendations. Here is the difference in plain English, why both matter, and what it costs.
What is SEO?
Search Engine Optimisation makes your website rank higher on Google and Bing for what your customers search. It covers on-page content, technical health (speed, crawlability, schema), and off-page authority (links, citations, reviews). Done well, it brings steady, compounding traffic that you do not pay per click for.
What is AI-SEO (GEO)?
Generative Engine Optimisation makes your business eligible to be quoted by AI answer engines — ChatGPT, Gemini, Perplexity and Google's AI Overviews. Instead of ranking a page, the goal is to be the source the AI names when someone asks "best X near me" or "how much does Y cost". It relies on correct schema, crawler access (GPTBot, PerplexityBot, Googlebot), an llms.txt, and quotable, factual content.
SEO vs AI-SEO — side by side
| SEO | AI-SEO (GEO) | |
|---|---|---|
| Where you appear | Google/Bing results | ChatGPT, Gemini, Perplexity, AI Overviews |
| Goal | Rank a page | Be the cited source |
| Key levers | Content, technical, links | Schema, crawler access, quotable facts, llms.txt |
| Who wins | Authority + relevance | Clear, structured, factual answers |
| Timeline | Months, compounding | Faster to appear once structured |
Why you need both in 2026
Search is not disappearing — most buyers still Google. But a growing share now asks an AI engine first and trusts the short list it gives. If you only do SEO, you win the old channel and miss the new one; if you only chase AI mentions, you have no foundation. The businesses pulling ahead do both, and the two reinforce each other — the same structured, factual content that ranks also gets quoted.
What it costs
| Service | Price |
|---|---|
| SEO | From ₹15,000/month |
| AI-SEO / GEO | From ₹20,000/month |
| Combined (recommended) | Scoped after a free audit |
How to start
Begin with a quick audit: is your site fast and crawlable, do you have correct schema and an llms.txt, is your content structured to answer real questions, and can AI crawlers reach you? Fix the foundation, then run SEO and GEO together. Cyber Defence does exactly this — and because we also build the website, the fixes are done at the source, not bolted on.
The honest bit
No agency can guarantee a Google position or an AI mention — anyone who does is guessing. What a real partner guarantees is the right foundation, honest reporting, and content that earns both. We publish our own llms.txt and do not oversell any single tactic. Explore AI-SEO services, GEO services and SEO services.
FAQ
What is the difference between SEO and AI-SEO (GEO)?
SEO ranks your website on Google and Bing; AI-SEO (GEO) gets your business named inside ChatGPT, Gemini, Perplexity and Google AI Overviews. SEO optimises pages; GEO optimises to be the cited source. In 2026 you need both to be found everywhere buyers look.
Do I really need AI-SEO in 2026?
Yes, if your customers ask AI for recommendations — and a growing share do. AI engines name only businesses structured to be quoted, via schema, crawler access and factual content. Without GEO you are invisible in that channel no matter how good your service.
How much do SEO and AI-SEO cost?
SEO starts around ₹15,000/month and AI-SEO/GEO around ₹20,000/month, with a combined plan scoped after a free audit. Pricing depends on your site's current state and how competitive your market is; you should get a clear scope before committing.
Can an agency guarantee a Google ranking or an AI mention?
No — nobody controls Google's algorithm or an AI model's output, so guarantees are a red flag. A real partner guarantees the correct foundation, honest reporting and content that earns rankings and citations over time, not a fixed position.
How do I start with SEO and GEO?
Start with an audit: site speed and crawlability, correct schema, an llms.txt, AI-crawler access and question-structured content. Fix the foundation, then run SEO and GEO together so the same content both ranks and gets quoted by AI engines.
