H & CO Agency

Based in Los Angeles, H & CO Agency works exclusively with jewelry and watch businesses: authorized dealers and multi-brand retailers, independent custom jewelers, DTC and wholesale jewelry brands, jewelry manufacturers, and pre-owned watch sellers. The team is small (1-10 people) and structured around senior strategists who manage client accounts directly rather than routing work through account managers. The agency frames its work around connecting ad spend to actual outcomes — online checkout, phone calls, or showroom visits — for high-ticket, considered purchases where buyers research over time before returning to buy. Services span five areas: web design and development (including Shopify builds with POS integration and migration support), paid media (Google Ads, Meta Ads, Pinterest Ads, and programmatic display, CTV, audio, and geofencing), social media marketing (organic and paid strategy, content production, influencer programs), search (technical SEO, local search, and a GEO/AI search offering aimed at citations in ChatGPT, Perplexity, and Google AI Overviews, plus a standalone SEO audit priced between $1,500 and $3,000), and AI and automation tools (AI-generated creative and ad variations, chatbots for after-hours lead capture, and daily reporting on inbox, site, and ad account activity). A stated attribution system ties individual ad clicks or taps to specific sales, matches in-store email captures back to the originating click, works around Safari cookie limits, and dedupes revenue reported across Google and Meta.
