Questions

London digital marketing FAQs

Forty second answers with no jargon. Anything else, ring the office and ask whoever picks up.

What does digital marketing cost?

From £3,000, and a typical project runs around six weeks. What moves the figure is scope, since a full campaign across content, paid and social is a bigger job than a strategy piece. Prices are published up front and hold once agreed.

What does the work cover?

Everything under one roof: strategy, branding, content, programmatic and paid ads, social, and SEO with AI search visibility. One small team runs all of it, so the campaign doesn't fall between departments and the creative matches the channel it lives in.

How will we know it's working?

On what lands in your inbox and your accounts. Every month you get a report from the person doing the work, and it leads with enquiries and revenue rather than reach. If a number doesn't connect to money, we won't dress it up as success.

Google Ads or SEO first?

Usually both, sequenced. Paid gets you enquiries while SEO is still warming up, then the ad spend tapers as organic takes the weight. If the budget only stretches to one, the answer depends on margins and how urgently you need work in the door, and we'll tell you which after the audit.

Do you work with businesses in London?

Yes. We're in Basildon, about 40 minutes from Fenchurch Street on the c2c, so a London meeting works in either direction. Come out to Chester Court or we'll come to you. Same team, same day, no city rates.

Can you do the branding too?

It's part of the offer. Branding folded into digital marketing in August 2026, so identity, rebrands and guidelines (from £3,500, four to six weeks) are planned alongside the campaigns they'll appear in. The point is coherence: one team, one direction, no brand book gathering dust.
