Contact us for an AI Visibility ReportSEO and GEO FAQs
What is GEO (generative engine optimisation)?
GEO is the practice of making your brand easy for AI engines like ChatGPT, Gemini, Perplexity and Google AI Overviews to understand, trust and cite. It builds on SEO with clear entity information, specific facts, FAQs, structured data and mentions on trusted third-party sites.
What’s the difference between SEO and GEO?
SEO helps your pages rank in Google’s search results. GEO helps AI engines mention and cite your brand in the answers they write. They share the same foundations, such as a technically sound site and clear, specific content, so we plan them together.
Do I still need SEO if people use AI to search?
Yes. Google is still the biggest source of search traffic, and AI engines draw on the same pages that rank well. Strong SEO makes GEO easier.
How do you measure GEO results?
We track a set of prompts that matter to your business, such as “best web development agency in Sydney”, and report whether ChatGPT, Gemini, Perplexity and Google’s AI Overviews mention you, how they describe you and which competitors they cite, using tools like Ahrefs Brand Radar. That sits alongside rankings in Search Console and traffic and leads in GA4.
What’s included in an AI visibility audit?
A review of how you rank in Google and appear in AI answers for your key services, your site’s technical health, content gaps and the third-party mentions competitors have that you don’t, with a prioritised list of fixes.
How long does SEO take to work?
Technical fixes can show results within weeks, while content and authority building usually take three to six months. GEO can move faster, because AI answers update as new content and mentions appear.
Can you protect our rankings during a website migration?
Yes. We map every URL, set up redirects, move metadata and structured data, and monitor rankings and errors after launch. Because we build websites too, migrations are part of the same project.
Do you do ecommerce SEO?
Yes. We work on category and product structure, faceted navigation, product schema and site speed, including for Adobe Commerce stores.
Do you do local SEO for Sydney businesses?
Yes. We optimise Google Business Profiles, keep name, address and phone details consistent across directories, and build location pages that rank in local results.
Can you work with our CMS?
Yes. Our developers work in AEM, Adobe Commerce, WordPress, Webflow, Sanity, Umbraco, Directus, Laravel and Next.js, so we can make changes ourselves rather than send you a list.
What does SEO cost?
Cost depends on the size of your site, how competitive your market is, and how much technical work and content you need. The audit is free, and after it you get a fixed monthly plan with clear priorities and reporting, so you know what’s being done each month and why.
Do you only do SEO for Sydney businesses?
No. We’re based in Surry Hills, Sydney, and do SEO and GEO for brands across Australia, including local SEO for businesses targeting particular cities.
