For decades, ranking on Google meant optimizing for a crawler — a bot that read your HTML, indexed your keywords, and matched your page to search queries. SEO was about signals: backlinks, page speed, keyword density, structured data. That model is changing fast. AI-powered search engines like ChatGPT, Perplexity, Google AI Overviews, and Microsoft Copilot don’t return a list of links. They generate an answer. When someone asks “What’s the best tool for tracking brand mentions in AI?” — the AI reads, synthesizes, and responds. Your page either gets cited or it doesn’t. Generative Engine Optimization (GEO) is the discipline of ensuring your brand, content, and expertise are what AI models reach for when generating those answers.

GEO doesn’t replace SEO — it extends it. A well-optimized page that ranks well in traditional search often gets cited in AI results too. But the signals that drive AI citation are different enough that GEO deserves its own strategy.

​
How AI models decide what to cite

AI search systems draw from two sources:

​
1. Training data

Large language models are trained on large corpora of text. Brands with strong, authoritative content published before and during training windows have a higher baseline presence.

​
2. Retrieval-Augmented Generation (RAG)

Most modern AI search tools retrieve live content at query time using semantic search. When a user asks a question, the AI fetches relevant documents from the web, then synthesizes an answer using those documents as grounding context. This is where GEO has the most leverage. By optimizing your content for retrieval — clear entity definitions, structured answers, authoritative tone — you improve your odds of being retrieved and cited.

​
The GEO playbook

1

Identify citation gaps

Find the prompts and topics where your competitors are being cited but you’re not. These are your highest-leverage opportunities.
2

Audit your content

Review existing pages for GEO signals: clear entity definitions, direct answers to common questions, structured data, and authoritative tone.
3

Create citation-worthy content

Publish content that directly answers the questions AI systems are asked. Structured formats (FAQs, listicles, comparisons) perform well in AI retrieval.
4

Track and iterate

Monitor your citation rate and visibility score over time. GEO is iterative — what works changes as models are updated and competitors adapt.

Key GEO metrics in Siftly

The percentage of AI responses to tracked prompts that include a mention or recommendation of your brand. Higher is better.
A composite score (0–100) combining citation frequency, sentiment, and competitive share of voice. Your headline metric for AI visibility.
Your brand’s citation percentage relative to the total citations in your market. A brand cited in 30 out of 100 responses has 30% SOV for that topic.
How many of the prompts Siftly tracks for your market include your brand in the response. Low coverage = opportunity.
When your brand is cited alongside competitors in a single response, what position is it mentioned at? First mention carries more weight.
GEO is an emerging field and AI search platforms evolve rapidly. Siftly’s analysis engine is continuously updated to reflect changes in how major AI systems retrieve and cite content.
