Hertford sits where two old trade routes meet, the River Lea and the A414, and its commercial character still reflects that. The core is independent. Maidenhead Street, Fore Street and Castle Yard host the kind of shops, restaurants and service businesses that London commuters discover after they move out and then stay loyal to for years. McMullen Brewery has been here since 1827, which sets a tone: this is a town that respects businesses with substance.
That matters for your website. Hertford customers research properly before they buy. A site that looks like it was built in 2014, or that takes four seconds to load on a phone, gets closed inside ten seconds. The businesses doing well in town have caught up to this. The ones who have not are losing ground every quarter, and they usually do not know why.
