When your ideal client asks ChatGPT, Perplexity, or Siri who the best specialist is in your field — does your business come up? If not, that's the gap I close. I'm an AI SEO content strategist with 15+ years of experience building content systems that get businesses found on Google AND recommended by AI search tools simultaneously. My specialty is AI search visibility — making sure your business is the one ChatGPT, Perplexity, Gemini, and Google AI Overviews cite when your customers ask. I work across all 10 platforms where customers now search: ChatGPT · Gemini · Perplexity · Siri · Alexa · Google · Google Assistant · Bing Copilot · Apple Intelligence · Meta AI ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ WHY YOUR CONTENT ISN'T RANKING (AND WHAT TO DO ABOUT IT) Most "SEO content" stopped working in 2024. Standalone blog posts don't build authority. Generic articles can't be cited by AI. And content without schema, speakable sections, or entity signals is invisible to ChatGPT, Perplexity, Gemini, and every voice assistant. I build content infrastructure — interconnected clusters of pillar pages, supporting articles, FAQ content, and location pages that establish deep topical authority fast. Every page is optimized at the section level for all 6 ranking signals: SEO — traditional Google ranking AEO — Answer Engine Optimization (featured snippets, People Also Ask) AIO — AI Overview Optimization (Google's AI summaries) GEO — Generative Engine Optimization (ChatGPT, Perplexity, Gemini) VEO — Voice Engine Optimization (Siri, Alexa, Google Assistant) E-E-A-T — Experience, Expertise, Authoritativeness, Trust This is the most effective approach to AI SEO in 2026 and beyond. ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ WHAT YOU GET WHEN YOU WORK WITH ME ✓ Full topical cluster architecture mapped before writing starts ✓ Complete keyword package per page (primary, secondary, LSI, voice, AI Overview targets) ✓ Up to 14 schema types per page in a paste-ready JSON-LD block ✓ Information Gain elements competitors can't copy ✓ Entity profiles with verified sameAs signals for AI recognition ✓ AI image generation prompts for every visual ✓ Publishing companion (GSC submission, distribution checklist, GBP post copy) ✓ 50+ point quality checklist verified before delivery — first draft is the final draft ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ INDUSTRIES I SPECIALIZE IN Medical aesthetics · Med spa · Plastic surgery · Legal · Dental · Real estate · Home services · Contractors · Pool service · Water treatment · Wellness · Professional services · Local service businesses YMYL compliance is automatic for medical, legal, financial, and real estate content — credentials, citations, and trust signals applied at the section level. ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ A FREE AI VISIBILITY SCAN FOR NEW CLIENTS Before we work together, I offer every prospective client a free AI Visibility Scan — an instant readout showing exactly where your business stands across all 10 AI platforms, with a list of 20+ AI prompts where your competitors are getting recommended instead of you. No credit card. No sales call. Just real data. ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ LET'S TALK IF YOU NEED: → AI SEO content writing (blogs, service pages, location pages) → AI search visibility strategy → Content cluster strategy and architecture → Schema markup and structured data → ChatGPT SEO and AI search optimization → Voice search optimization for Siri, Alexa, Google Assistant → Generative Engine Optimization (GEO) → Answer Engine Optimization (AEO) → E-E-A-T content writing for YMYL industries → Local SEO content → Topical authority building → Pillar page and spoke page development → FAQ schema implementation → Site architecture audits → Competitive content gap analysis Send me a message with your website URL and what you're trying to fix. I'll tell you honestly whether I'm the right fit. - Joy Herro

➡️My App Store Optimization earned the #1 ranking on the App Store Games - Trivia category in under 1 month for DAFUQ, a previously unranked app. I’ve worked with 150+ apps of all sizes, from startups to global brands like Hard Rock and MGM, achieving impressive results. My experience includes working on more than 15 top-100 apps, with notable examples like BetMGM Sportsbook (#4), Stadium Live (#9), Hard Rock Neverland Casino (#43), Timeleft (#55), Vivino (#38), Qmee (#20), Stronger (#37), DMV Genie (#88) Novel Effect (#47), Minutes (#57), Sole Supplier (#88), DMV Genie (#88), Sole Supplier (#90), and more. [ DATA-DRIVEN APPROACH ] These results come from a transparent, data-driven approach that focuses on improving keyword rankings on both Google Play and the App Store, improving organic downloads, conversion rates, retention rates, app ratings, and ultimately work to grow in-app purchase and subscription revenue. [ INDEPENDENT FREELANCER – I DO ALL THE WORK MYSELF ] Let's set up a free, 30‑minute video screenshare call 📞 to discuss how I can help your app achieve long‑term organic growth. Just send me a message, and I’ll share my calendar 📅 via Upwork. [ QUANTIFIABLE SUCCESS STORIES ] • Increased 21Moves’ monthly subscription revenue from $500 to $10,000 in just 3 months. • Boosted Qmee’s organic downloads from 13,000 to over 70,000 per month in 2 years. • Launched an ASO strategy that generated over $100,000 in monthly revenue. • Scaled apps to earn more than $300,000 per month. [ MOBILE APP MARKETING SPECIALITIES ] • ASO Metadata Optimization • Keyword Research • Cross-Localization (Japanese, Korean, French, etc.) • 7-Figure Apple Search Ads (ASA) Ad Campaigns • App Store Screenshots • App Preview Videos • Custom Product Pages (CPP) • Product Page Optimization A/B Testing • Conversion Rate Optimization (CRO) • App Ratings & Reviews Growth • In-App Events • Push Notifications & In-App Messaging Drip Campaigns • App Onboarding User Flow • User Retention Strategies • In-App Purchases & Subscriptions • App Development Feature Roadmaps [ NO PREDATORY TACTICS ] I can't stand agencies that fail to deliver on their promises. Too many make excuses like shifting market conditions, algorithm updates, low budgets, or increased competitor spending, rather than taking responsibility and adapting their strategy. Their focus is often on extracting as much money as possible before clients realize the strategy isn’t working. I don’t operate that way. My approach is transparent, data-driven, and built around real results, not empty promises. [ YES TO DATA ] I don't pretend to have superhuman intuition. I know how to find, understand, and apply ASO data to create and improve your app store product page. How to measure the impact of the ASO efforts is just as significant, so we're confident in the effects of the ASO efforts. No, "it sounded good" is not a sufficient explanation. Whether you’re an indie developer or a large studio, my ASO strategies can help you reach more users, improve conversion rates, and build long-term organic growth. Let’s talk about how I can help your app achieve its full potential.
