The Client: Lilium Diagnostics is a trusted provider of PCR and COVID-19 antibody testing services in Montreal, Quebec. The company offers reliable, fast, and convenient testing solutions for travelers, businesses, and individuals.

Objective: The goal of this SEO campaign was to enhance the website's organic visibility, increase traffic, and improve keyword rankings for high-intent medical testing queries. Given the competitive nature of healthcare-related searches, we focused on strengthening local SEO, resolving technical issues, and implementing a data-driven content strategy to secure top positions for relevant keywords.

The Challenge

Low presence in non-branded search results – Most traffic was branded, limiting the site's ability to attract new customers.

Technical SEO issues – Hreflang errors, orphan pages, inconsistent NAP details on Google My Business, and multiple H1 tags impacted performance.

Lack of high-quality backlinks – Weak link profile reduced domain authority.

Local SEO inconsistencies – Google My Business listing was not fully optimized, affecting rankings in local search.

Keyword visibility gaps – The website was not ranking in the top positions for high-intent commercial queries related to PCR testing.

What we did

Technical SEO Fixes – Conducted a comprehensive website audit and resolved hreflang errors, optimized NAP consistency, fixed orphan pages, and corrected multiple H1 tag issues.
