The service is specifically designed for health and wellness practices in Montgomery County, Pennsylvania and New Jersey (Bergen County and South Jersey Shore corridor). ### How it works A structured, geo-matched article is written for the practice and published on a verified local news publication covering their exact geographic zone. The article is formatted as a community announcement — not marketing copy — so Google's AI can extract clean, trusted entity data about the practice. ### Why it works Google AI Overviews apply a strict geographic proximity filter when sourcing local entity data. A publication covering Horsham carries no weight for a practice in Collegeville. Each article is matched to the correct publication zone for the practice's physical address. ### Target markets **Pennsylvania — Montgomery County:** Lansdale, Hatfield, Montgomeryville, Horsham, Hatboro, Willow Grove, Ambler, Blue Bell, Lower Gwynedd, Whitpain, Collegeville, Skippack, Trappe, Schwenksville **New Jersey — Bergen County:** Ridgewood, Paramus, Glen Rock, Fair Lawn, Hackensack, Mahwah, Ramsey, Teaneck **New Jersey — South Jersey Shore:** Ventnor, Margate, Longport, Sea Isle City, Ocean City ### Practice types served Dentists, dental surgeons, orthodontists, cosmetic dental practices, physical therapists, rehabilitation clinics, chiropractors, dermatologists, medical spas, mental health counsellors, therapy practices. ### Pricing **Pennsylvania:** - Single Zone — $149 (one article, one publication) - Overlap Corridor — $249 (two articles, two publications) - Full County Presence — $349 (three articles, three publications) **New Jersey:** - Single Zone — $199 - Shore Double — $299 (both South Jersey Shore publications) - Full NJ Presence — $399 (all three NJ publications) ### Add-ons (both markets) - Medical Directory Listing — $109 - Medical Authority Profile — $109 - Mental Health Authority Profile — $109 (mental health practices only) - Fast-Track Indexing — $99 (DA 90+ syndicated placement, 6-month duration) ### Pages - `/miami-ai-search-optimization-agency` — Miami AI Search Optimization Agency (English) — commercial hub for AI search optimization services.

SEO optimises for ranking. AEO optimises for answers. AI-Ready Publishing optimises for extraction. **Answer Density** — how much of a retrievable content block directly answers the question being asked. High Answer Density means the opening section contains a direct, specific answer with named entities. Low Answer Density means the opening section contains introductions, context, background or marketing language without substantive answers. **HTML Noise** — structural content that appears before the article body in a page's HTML source — navigation menus, promotional banners, breadcrumbs, author metadata, affiliate disclosures, social sharing buttons — which AI retrieval systems evaluate as part of the first content block before reaching the substantive article content. ## Pages * `/` — Homepage and free AI visibility checker * `/history` — Pro scan history dashboard * `/blog` — AEO, GEO, and AI search guides * `/thankyou` — Pro activation page * `/blog-chatgpt-mentions` — How to get your brand mentioned in ChatGPT answers * `/seo-vs-aeo-vs-geo` — SEO vs AEO vs GEO: The Definitive 2026 Comparison — reference page covering definitions, comparison table, decision framework and FAQ for all three disciplines * `/blog-aeo-vs-seo` — SEO vs AEO vs GEO: What's Actually Different in 2026 * `/blog-competitor-ai-search` — Why competitors appear in AI search while your brand does not * `/blog-zero-click-search` — Zero-click search and what it means for brands * `/blog-content-for-ai` — How to write content AI systems are more likely to reference * `/blog-free-ai-visibility-checkers` — Best Free AI Visibility Tools & Trackers in 2026 * `/blog-does-chatgpt-recommend-brands` — Does ChatGPT recommend brands? * `/blog-what-does-ai-know-about-your-brand` — What does AI know about your brand? * `/blog-ai-reputation-monitoring` — AI Reputation Monitoring: How to Track What AI Says About Your Brand * `/blog-what-does-chatgpt-say-about-your-brand` — What Does ChatGPT Say About Your Brand? * `/blog-monthly-ai-reputation-audit` — How to Run a Monthly AI Reputation Audit * `/blog-is-your-brand-invisible-to-ai` — Is Your Brand Invisible to AI? * `/blog-what-to-do-when-ai-gets-brand-wrong` — AI Got Your Brand Wrong: Now What? * `/blog-why-ai-recommends-competitors` — Why AI Recommends Your Competitors (And Not You) * `/blog-ai-visibility-gap` — The AI Visibility Gap: What It Is and How to Close It * `/blog-ai-brand-monitoring-for-agencies` — How to Add AI Brand Monitoring to Your Agency Services * `/blog-does-ai-recommend-your-saas` — Does AI Recommend Your SaaS?
