Image SEO for CHC E-commerce

Alt text, file names, metadata, visual search: the complete technical guide to making your product images work as hard for SEO as they do for conversion -- on Amazon, Google, and American e-pharmacies.

Introduction: Your Images Are SEO Assets, Not Just Conversion Visuals

Most Consumer Healthcare (CHC) e-commerce teams know that product images are decisive for conversion. What's less known is that these same images play a direct and measurable role in your product visibility -- in Google Images, in enriched organic search results, on marketplace internal search engines, and now in AI-powered visual search.

In the United States, the online health and wellness market continues its strong progression, with annual growth of approximately 18%. Yet online sales still represent less than 15% of total healthcare retail sales. This means competition for visibility is fierce: every position gained in search results represents a disproportionate competitive advantage in a market still in conquest phase.

And here's the point many brands underestimate: Google indexes billions of images, and Google Images represents a significant portion of all searches performed. For queries like "magnesium supplement reviews," "natural nasal spray," or "baby sunscreen chemical-free," image results now appear directly in universal search results -- not just in the Images tab. A poorly optimized image means a door to your product page stays closed.

This technical guide is designed for SEO teams and content teams of CHC brands operating in the American market. It covers the full spectrum of image optimization: alt text, file names, metadata, quality signals, AI visual search, and the specificities of key platforms (Amazon, CVS Pharmacy, Walgreens, Google Shopping).
