I'm Aman, a Local & Technical SEO specialist with 6+ years of experience and a 100% Job Success Score across 28 completed projects on Upwork. Over the last year, I've expanded my focus into AI Search Optimization — Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) — so my clients don't just rank in traditional search, they get surfaced and cited as the recommended answer inside AI Overviews, ChatGPT, and Perplexity. What I do: AI Search Visibility (GEO/AEO) Structuring content, schema, and entity signals so AI systems can find, trust, and cite your business as a source. This includes optimizing for direct-answer formats, FAQ structuring, and the E-E-A-T signals AI systems weight heavily before citing a brand. Local SEO & Google Business Profile Multi-location GBP optimization, local citation building, review generation strategy, and local schema markup that gets you found in map packs, "near me" searches, and AI-generated local recommendations. Technical SEO Full-site audits, crawlability and indexation fixes, Core Web Vitals and page speed optimization, XML sitemaps, structured data implementation, and broken link cleanup. On-Page & Content SEO Keyword research, competitor gap analysis, on-page optimization, and content built to satisfy both human readers and AI parsers — clear structure, concise direct answers, and entity-rich language. Link Building & Authority White-hat backlink strategy, guest posting on high-DR sites, and digital PR angles that build the authority signals both Google and AI systems reward. My process: Audit — I map your current visibility across Google, AI Overviews, and AI chat tools, and identify exactly where you're losing ground. Strategy — You get a prioritized action plan tied to business outcomes, not vanity metrics. Implementation — I execute the technical, content, and local fixes myself — no handoffs, no delays. Reporting — Monthly tracking against rankings, AI citation appearances, and organic traffic, in plain language. Recent results: Delivered technical SEO and schema fixes for a law firm client that improved on-page structure and Google Business Profile performance across a multi-project engagement Built and executed a high-volume local SEO + GBP model for UK SMEs across multiple ongoing fixed-price contracts, maintaining a 5.0 rating throughout Managed city/state landing page rollouts for multi-location businesses to improve local search coverage Tools I use: Google Analytics, Google Search Console, Ahrefs, Moz Pro, Screaming Frog, Semrush A few quick answers to what clients usually ask me: Do you only do traditional SEO, or AI search too? Both. Traditional SEO is still the foundation — AI systems pull from the same authority and technical signals Google does — but I layer AI-specific structuring on top so you're visible in both. Can you handle multi-location or franchise SEO? Yes — this is one of my core specialties, including city/state landing pages and multi-location Google Business Profile management. Do you write content, or only optimize? I handle both — content structuring/optimization for AI and human readers, plus technical and local SEO execution. What's the first step if we work together? A short audit of your current visibility across Google, AI Overviews, and AI chat tools, so we both know exactly where the opportunity is before any work starts. If you want a strategy call to map out where your business is losing visibility — and a clear plan to fix it — message me. I respond fast and I'm currently accepting new clients.
