FAQ
Digital marketing: frequently asked questions
Can’t find your answer? Our digital marketing team is happy to help.
What is the main purpose of digital marketing?
To connect your business with the right audience in a way you can measure: more visibility, better-quality traffic, and more enquiries and sales for long-term growth.
Why outsource digital marketing to experts?
You get a full team of specialists, from SEO and paid ads to web developers, for less than the cost of one in-house hire. We keep up with changing algorithms and AI search so you can focus on running your business.
What is Generative Engine Optimisation (GEO)?
GEO helps your business get cited and recommended by AI tools such as ChatGPT, Gemini and Google AI Overviews. As more customers use AI to find suppliers, it makes sure your brand is part of the answer.
How does your IT background help my marketing?
Unlike creative-only agencies, we have a deep technical foundation. Your website is fast, secure and well hosted, and we fix the technical problems that often hold marketing back.
How long does it take to see results?
Technical fixes take effect straight away. Organic growth usually builds momentum over three to six months, while local visibility in Google Maps can improve sooner. PPC can bring leads from day one.
Where do you provide digital marketing services?
We are based in Dartford, Kent, and focus on Kent and London, but we work with clients throughout the UK and worldwide.
Do you offer bespoke strategies for SMEs?
Yes. We look at your industry, competitors and goals and build a plan that makes the most of your budget. We do not sell one-size-fits-all packages.
Do you offer a free consultation?
