51Blocks was contracted by Integrity Fire Safety Services, a startup company, to establish their online presence. The company created a WordPress website for Integrity Fire Safety Services and currently manages it. They also worked on SEO and lead generation, and manage a chat feature on the site, interacting with customers and ensuring they get directed to the right people. 51Blocks also provides content for the company's blog. The partnership, which began in January 2018, has seen an investment of about $40,000 by Integrity Fire Safety Services. The CEO of the company commended 51Blocks for their honesty and shared values.

Smileworks Liverpool, the UK's largest and fastest-growing independent dental practice, hired 51Blocks to update their blog site which had become slow and hard to navigate following a recent update. The company was tasked with making the blog more mobile-adaptive, which they achieved by adding larger fonts that were easier to read on small screens and visible in WordPress' visual mode for easy formatting by non-technical editors. They also backed and reinstalled the entire database, altered the frontend based on design insights gained from heatmaps, research, and data, upgraded security features, and refined the legacy code to improve site speed. The project, which was completed in October 2018, cost less than $10,000. The CEO of Smileworks Liverpool expressed confidence in 51Blocks due to a referral from a reputable local SEO consultant and positive comments from another SEO company.
