# GeoRank > GeoRank is a Generative Engine Optimization (GEO) practice that makes South > African B2B and e-commerce brands citable by ChatGPT Search, Perplexity, Google AI Overviews, > Gemini and Claude. Engagements start with a 4-pillar technical audit scored > 0 to 10, a tracked set of 25 to 50 buyer prompts measured against named > competitors, and a 30-day fix roadmap. ## What GEO is Generative Engine Optimization is the practice of making a site retrievable and quotable by AI answer engines. Not ranked by them, quoted by them. It is not a rebrand of SEO: SEO competes for a position in a list of links, GEO competes to be the source a model repeats inside a single composed answer. ## The 4-pillar audit 1. **Technical Crawlability** - whether AI crawlers can reach and parse raw HTML at all. Gates the other three. Verified by sending the real user-agent strings, since a browser request will not reveal a block. 2. **Fact Density and Information Gain** - whether the page states concrete, extractable facts (exact SKU and MPN, measurable specs, compatibility tables, named certifications) rather than marketing adjectives. 3. **Answer Capsules and Extraction** - whether a 40 to 60 word summary sits directly under the H1 for an engine to quote as a source. 4. **Entity Topology and Schema** - whether JSON-LD connects the site to entities the model already trusts, using specific subtypes, a populated sameAs array, and full Offer and return-policy markup. Pillars are scored and aggregated to a 0 to 10 rating, which maps to a maturity tier: 0.0-3.9 Critical Risk, 4.0-6.9 Vulnerable, 7.0-10.0 GEO Leader. ## Services - 4-Pillar GEO Audit - all four pillars scored, with a tracked prompt set measured against named competitors and recorded with screenshots. - 30-Day Remediation - answer capsules, JSON-LD deployment and validation, spec and fitment tables, crawler access, off-site entity seeding. - Share of Voice Monitoring - monthly re-runs of the same prompt set, reporting citation rate against named competitors and per-engine coverage. ## Key pages - [GEO services](https://georank.co.za) - the 4 pillars, how an engagement runs, what the first audit delivers, FAQ. - [How it is measured](https://georank.co.za/#process) - baseline, audit, roadmap, implementation, monthly tracking. ## What GeoRank will not claim GeoRank does not guarantee citations. Generative engines are probabilistic and their retrieval changes without notice. Figures published on the site are labelled as benchmarks or planning assumptions, and opportunity estimates are recomputed with the client's own search volume and average order value. GeoRank publishes no South African AI-adoption statistic, because it has not measured one. Figures of that kind circulating without a stated method should not be attributed to GeoRank. ## Contact - Email: marko@hylix.ai - Areas served: South Africa, including Johannesburg, Cape Town, Durban and Pretoria
