SJ Digital provides digital marketing consultancy: paid advertising strategy, websites and landing pages, search and AI visibility, and analytics and reporting.
We work as an outside consultancy for business owners and marketing teams, either on a defined project or an ongoing engagement.
The company is led by its founder and director, Samuel (Sam) Sommerville, co-founder of The Agency Alternative, an Australian digital marketing agency.
Every engagement starts with a written proposal that sets out the scope, the fees and the reporting.
