Web design in Cannington for the trades and suppliers working Perth's Albany Highway corridor.

Two businesses can share a Cannington postcode and have nothing in common in search. One sells to people who are physically near it. Westfield Carousel is the largest shopping centre in Western Australia and pulls foot traffic in from across the southern suburbs, so for a business in that catchment the map listings at the top of a local search do the heavy lifting, because proximity is weighted heavily and the searcher is usually already close. The other sits behind it in Welshpool, where the warehouses, transport yards and trade suppliers serve the entire metro area. Their buyers search by product and by Perth, not by Welshpool.

The housing stock splits the corridor again. Cannington, East Cannington, Queens Park and Bentley are 1950s to 1970s homes carrying heavy infill and subdivision, so much of the trade demand is strata and rental maintenance, subdivision earthworks and retaining, and plumbing and electrical work on services that were never sized for four dwellings on one old block. Much of that is booked by a property manager from a desk rather than an owner in a panic, which is a different search and a different page. Bentley adds another layer again with Curtin University and the technology precinct sitting inside it.

The river side of the corridor behaves nothing like that. Wilson, Shelley and Rossmoyne are 1960s and 1970s homes on larger blocks near the Canning River, bought by owners who stay, so the work is renovation, roofing and the slow upgrade of a house somebody intends to keep. It is one highway from Kenwick and reads as a separate market. Albany Highway, Leach Highway, Welshpool Road, Orrong Road and Roe Highway all converge here, which is why so many trades base themselves in the corridor and why a Cannington service area is usually wider than the suburb name suggests. The Armadale line through Cannington and Beckenham has been rebuilt as elevated rail, so even the way people describe getting to you has changed.

The structural answer is not a page per suburb. It is a page for each way the business is actually bought, with area pages only where the jobs, the access or the questions genuinely differ. Where there is no work in a suburb yet, it belongs in the service area.
