Stourbridge sits in the Dudley borough administratively while retaining a strong sense of its historic Worcestershire identity, and residents are clear about the distinction. A business marketing to Dudley borough, or to Birmingham, speaks to a customer who does not recognise the description.
Difficulty for Stourbridge terms is low, which means naming the town explicitly is both the easiest and the most effective thing most local businesses could do.
The glass industry is genuinely distinctive
Stourbridge was the centre of English crystal and cut glass, and that heritage still supports glassmaking, studio glass, restoration and specialist retail. Those businesses serve a national and international customer who searches by craft and product — “hand cut crystal”, “glass restoration” — rather than by town, and their pages should be written for that audience rather than a local one.
The wider catchment crosses the boundary
Stourbridge serves Hagley, Kinver, Wollaston, Amblecote, Lye and out toward Kidderminster and Bromsgrove, which crosses into Worcestershire. Naming those places captures searches the town name alone will miss, and competition in them is very light.
An affluent southern edge
Norton, Pedmore and Hagley are noticeably more affluent than the borough average, and what converts there differs — credentials and evidence rather than price. Each searches separately.
What we would do first
Claim Stourbridge by name rather than Dudley, name the villages including the Worcestershire ones, and separate any national craft or restoration work onto its own pages. Those three moves cover most of what matters here.
