A leading healthcare group in Southern California sought a digital marketing partner to help them expand their reach, engage both English and Spanish-speaking audiences, and drive measurable results across multiple channels. With a robust website and a diverse content offering, they needed a team to implement and optimize their marketing strategy, focusing on technical SEO, content, advertising, and social media.

Opportunity

Several growth opportunities were present. The organization has access to a large, bilingual audience with distinct content interests in the lifestyle realm, including seniors, families, individuals with chronic illnesses, local activities, and wellness topics. There was strong potential for organic growth through SEO and content marketing, as well as untapped potential in paid social and email marketing.

‍

Objective

The objective was to increase website traffic, engagement, and conversions by focusing on several key strategies. This includes improving technical SEO and overall site health, expanding and optimizing bilingual content to better serve both English- and Spanish-speaking audiences, and growing and engaging audiences through paid advertising and social media efforts. We also aimed to improve email marketing performance and proactively adapt to industry changes, particularly those related to the evolving impact of AI on search.

Challenges

However, there were also notable challenges. The healthcare search landscape is highly competitive and has been significantly impacted by changes in Google’s search algorithms and the rise of AI Overviews, both of which have affected organic click-through rates. Additionally, they had technical SEO issues to address, such as thousands of site errors and duplicate content. Audience engagement and conversions also experience seasonal fluctuations, and there is a continuing need to balance content for both English- and Spanish-speaking users.
