Questions from Harpenden businesses
Do you have an office in Harpenden?
No. Our office is in Luton, about 6 miles away, at 33 Kenilworth Road, LU1 1DQ. We’re happy to meet Harpenden clients there by appointment, or on a video call.
How much does digital marketing cost for a Harpenden business?
Our monthly plans start from £149, and one-off website builds start from £995. Every package starts with a free audit, so you’ll know exactly what you need before spending anything. See full pricing.
We already get word-of-mouth referrals. Do we need marketing?
Referrals are great, but most people still look you up online before they get in touch. If your website, Google profile and reviews don’t back up the recommendation, some of those referrals quietly go elsewhere. A free audit will show whether that’s happening.
How long does local SEO take to work?
Most businesses see early improvements in two to three months, with stronger results building over six months and beyond. Paid ads can bring enquiries much faster while SEO grows.
