Hanhan Interactive

Hanhan Interactive works out of La Mesa, California, and has operated as a San Diego SEO and web design agency since 2004. The firm concentrates on search engine optimization and conversion-focused web design, building customized SEO and Local SEO strategies rather than applying a single template across clients. Businesses come to the agency for a custom strategy aimed at acquiring quality online traffic, not just volume.

Services split between search engine optimization, web design and development, and PPC management. SEO campaigns are structured to build long-term website visitor traffic over time, while Pay-Per-Click campaigns are used when a client needs immediate traffic rather than a slower organic build. The web design and development process is oriented toward producing sites that are both aesthetic and marketing-driven, meaning design decisions tie back to conversion goals. Clients working with the agency have described the core team as knowledgeable, creative, and attentive throughout the process.

Past project work spans several formats. Perkins Mobile received a dedicated mobile website, while Marie Callender's got a desktop site paired with a custom responsive/mobile hybrid build. The Shea Center needed a donation-drive program that was easy to use and manage, and Fumari's project involved a custom-designed eCommerce website. The agency has also worked on a project tied to the Federal Trade Commission's Weight Loss Challenge. Across these engagements, the pattern is consistent: SEO and design work built around the specific traffic and conversion needs of each client rather than a one-size-fits-all package.
