SEO, Search Engine Optimization

Traditional search optimization focused on ranking your website in Google search results.

Keyword research that matches what real customers search for
On-page SEO: titles, headings, descriptions, image alt text
Backlinks from trustworthy local and industry sources
Technical SEO: speed, mobile, sitemap, structured data

AEO, Answer Engine Optimization

AEO helps your business become the direct answer in AI summaries, voice search, and Google's featured snippets.

Featured snippet-style content that answers a question in one or two short paragraphs
Voice-search-friendly phrasing that sounds like how people talk
FAQ sections on every service page
Direct, confident answers, not vague marketing copy

GEO, Generative Engine Optimization

GEO helps AI systems like ChatGPT, Claude, and Perplexity understand and recommend your business inside AI-generated responses.

Structured content with clear headings and sections
Context and clarity in every paragraph
Authority signals: reviews, case studies, real client names
AI readability: plain language, short sentences, no jargon

Practical tips that work for all three

Write content that answers real customer questions
Use clear headings and a logical page structure
Add FAQ sections to your most important pages
Create location-based service pages if you serve specific areas
Keep content updated regularly so search engines see your site is alive

Do I have to choose between SEO, AEO, and GEO?

No. They overlap heavily. Strong SEO foundations also support AEO and GEO. Different goals, one strategy: be findable everywhere.

Which one should a small business focus on first?

Start with SEO basics, clear messaging, service pages, Google Business Profile. Once that's solid, layer FAQs and clearer structure on top to support AEO and GEO.

Is GEO replacing SEO?

No. GEO is a new layer on top of SEO. Google still drives most discovery for small businesses, but a growing share of customers now ask AI assistants too. You need both.

How do I know if GEO is working?

Open ChatGPT, Claude, or Perplexity in a clean session and ask for recommendations in your industry and city. If you appear, GEO is working. If you don't, your foundations need more clarity.
