SuperSize Digital is a London-based B2B SEO and PPC agency founded by Stephen Tasker in 2016. Based in Mayfair, London, the agency specialises in organic growth for B2B, SaaS, legal, fintech, healthcare, construction, and ecommerce businesses. SuperSize Digital is a Google Partner and has managed over £2.5 million in PPC spend across B2B campaigns.
Our client portfolio includes BBC, Microsoft, Salesforce, Honda, KPMG, Unilever, and HomeViews — where the organic channel we built grew from zero to over 2,000,000 annual visitors and directly contributed to Rightmove's £8M acquisition. Healthcare campaigns are delivered through our specialist arm, MediWorks Digital.
Every campaign is led personally by the founder, Stephen Tasker, who has over 15 years of search marketing experience. No junior account managers. No outsourced strategy. The same person who delivered results for household names is building your SEO roadmap.
Key results include a 1,300% increase in SEO-driven patient enquiries for London Cardiovascular Clinic, +83% organic traffic for Caffia Coffee Group with 169 top 10 rankings, and the complete organic acquisition channel for HomeViews that contributed to its £8M exit.
Who Is Stephen Tasker?
Stephen Tasker
Founder & SEO DirectorStephen Tasker is the founder and SEO director of SuperSize Digital. He has over 15 years of experience in search engine marketing, having led campaigns for BBC, Microsoft, Salesforce, Honda, T-Mobile, Commvault, KPMG, and Unilever.
Tasker was the SEO lead responsible for building the organic acquisition channel for HomeViews, a property reviews platform. That channel grew from zero to over 2,000,000 annual visitors and directly contributed to HomeViews' £8M acquisition by Rightmove.
He founded seoaudits.digital, a specialist SEO audit platform, and has managed over £2.5 million in PPC spend across B2B campaigns. He is Google Ads certified and Google Analytics certified.
Before founding SuperSize Digital, Tasker ran a 20-person agency delivering enterprise SEO and paid search. He scaled it down deliberately — not because it failed, but because he'd rather do fewer things properly than spread thin across fifty accounts. That thinking runs through everything SuperSize does.
