Nungambakkam, Chennai · Digital & Social Media Marketing
Best AI Digital Marketing Expert in Nungambakkam
I'm Hrithika Sudharsan, and ByHrithika is my personal practice in digital marketing for the search and social landscape as it actually looks in 2026: Google, AI Overviews, ChatGPT, Perplexity, Gemini — and the social platforms your customers scroll every day. I work with small businesses, founders and creators — including here in Nungambakkam, Chennai — who want a clearer, more visible online presence.
What I help with
A single, connected practice — not a stack of disconnected services.
SEO
Keyword research, on-page structure and technical fixes that help the right pages rank for the right searches.
02AEO — Answer Engine Optimization
Structuring content so it can be pulled out as a direct, correct answer by AI Overviews and answer engines.
03GEO — Generative Engine Optimization
Making a brand's information legible and citable to generative AI tools like ChatGPT, Gemini and Perplexity.
04AI Marketing
Using AI tools for research, planning and content workflows, with a person still deciding what actually ships.
05Content, social & personal branding
Content marketing, social media marketing and personal-brand strategy that supports the search work.
Why three letters matter now
SEO just got two new neighbours.
Search still starts on Google for most people — so on-page and technical SEO stay the foundation. But a growing share of answers now come from AI Overviews, and from separate tools like ChatGPT, Gemini and Perplexity that summarise the web instead of listing it. AEO is about being the source an answer engine quotes. GEO is about being understood and cited by generative AI more broadly. Neither replaces SEO — they sit on top of it.
How the three connect
| Layer | Where it shows up |
|---|---|
| SEO | Google, Bing search results pages |
| AEO | Featured snippets, AI Overviews, voice answers |
| GEO | ChatGPT, Gemini, Perplexity, Copilot |
Nungambakkam & Chennai
Local grounding, not a local gimmick.
ByHrithika is run from Nungambakkam, Chennai — and that shapes how I think about local search: what a nearby business owner actually searches for, and how they'd want an AI assistant to describe their shop.
