Salient Bio are an award-winning London-based laboratory. They offer a range of state-of-the-art services including blood and stool pathology, microbiome analysis for medicine, research and industry, and industry-leading metagenomic sequencing services.
We worked with Salient over a 9-month period to improve organic Google rankings for key terms and services. They were in a particularly challenging SEO position as a small, independent lab competing against household names with global resources such as Randox and Boots, plus leading private hospital chains and NHS trusts.
