SEO has changed. People don't only search Google now. They ask AI.

They ask ChatGPT. They ask Perplexity. They ask Google AI Overviews. They ask Claude. If your content isn't cited in those answers, you can lose traffic - even if you rank well. That's where GEO comes in.

What is GEO?

GEO stands for Generative Engine Optimization. Traditional SEO is about ranking blue links. GEO is about getting cited inside AI-generated answers.

The goal is different. Traditional SEO wants a click. GEO wants a citation. Sometimes a citation gets no click at all. That's fine. The mention still builds authority. But it changes how you write, how you structure pages, and how you measure success.

How SEO changed in 2026

The numbers are clear. AI search visits grew 42.8% year over year. They went from 15.6 billion in Q1 2025 to 27.4 billion in Q1 2026. Google search visits grew just 2.4%. And where AI Overviews appear, click-through rate for the top page can drop by up to 58%.

So rankings still matter. But selection matters more. AI systems look at brand authority, structured data, and real-world mentions. They don't just match keywords. GEO is mostly strategy. Only part of it is technical.

Is AI useful for SEO?

Yes. But not as a content generator. AI is most useful for audits, structure analysis, and citation-readiness scoring. That's what the geo-content Claude skill does.

It checks content for E-E-A-T signals. It also checks AI citability. E-E-A-T now applies to all competitive queries. Not just YMYL topics. Google updated its Quality Rater Guidelines in December 2025.

Skill to automate site audits

The geo-content skill is part of the geo-seo-claude repository. It installs into Claude Code. It fetches target pages. It scores E-E-A-T across four dimensions. Each dimension is worth 25 points. It also checks content quality, AI content signals, and topical authority.

Then it outputs a report called GEO-CONTENT-ANALYSIS.md. You can turn that into a PDF. It's production-ready. There's also a video walkthrough here:

Pros

Quick way to analyze sites.
Delivers a production-ready report.
Clear 100-point E-E-A-T scoring model.
Transparent SKILL.md. You can read it before running.
Simple install command.
Good for focused audits.

Cons

Claude Code requires a paid subscription or API key.
Token use can be heavy.
A coding agent re-sends the conversation on every turn. So tokens burn fast.
Anthropic's average is $13 per developer per active day. That's $150 to $250 per month.
The $20 Pro plan includes Claude Code. But it has usage limits.
Max plans cost $100 to $200 per month.
Large sites may drain the $20 plan fast.
Pay-as-you-go at scale can get expensive. It can reach thousands per month.

What site size can the $20 plan handle?

A small site with 10 to 20 pages? Usually fine. A medium site? Maybe a focused audit. Not a full crawl.

A large site with hundreds of pages? It will likely hit limits. Enterprise sites? Use an API or team plan. Budget carefully. So the $20 plan is a good starting point. It is not a bulk crawling tool.

geo-content/SKILL.md

The skill file is transparent. It lists allowed tools: Read, Grep, Glob, Bash, WebFetch, Write. It lists the purpose and the scoring framework. You know what it does before you run it.

Conclusion

GEO is not a replacement for SEO. It is an extension. AI engines crawl the same web. Technical health, authority, and site architecture still matter.

The geo-content skill is a useful entry point. It helps you measure citation-readiness without building a custom pipeline. The trade-off is cost and token use. So use it for focused audits. Use it on high-value pages. Don't use it to bulk crawl entire domains unless you have the budget.
