By the Numbers: Perth's Duplicate Image Problem Is Costing Local Businesses More Than They Realise

Perth businesses are sitting on a largely invisible liability. Across the city's property listings, government procurement portals and retail e-commerce platforms, duplicate and placeholder images — stock photos recycled across multiple pages, or product shots used twice without metadata variation — are undermining digital performance in ways most operators have never measured.

The timing matters. Western Australia's economy is running hot, and the competition for digital attention has sharpened considerably. Metronet station precinct developments along the Thornlie-Cockburn Link corridor have pushed a wave of new apartment listings onto platforms like realestate.com.au and Domain, many of them from small and mid-tier developers who reuse the same renders across dozens of individual property pages. Defence industry contractors clustering around HMAS Stirling at Garden Island and the Henderson Marine Precinct south of Fremantle are rapidly building out web presences to compete for AUKUS subcontracts. And a sustained immigration-driven housing demand surge has flooded the rental market with near-identical property imagery.

What the Data Actually Shows

Google's publicly documented guidance on duplicate content has long warned that pages sharing substantially identical images — particularly where the alt-text and filename metadata are also copied — can be assessed as lower-quality results. Research published by SEMrush in 2023 found that e-commerce pages with duplicate product images had, on average, 29 percent lower organic click-through rates than pages using unique visual assets. While that figure covers global data, digital agencies operating in Perth's CBD, including firms on St Georges Terrace and in the West Perth tech precinct, report the pattern is consistent with what they see locally.

The scale of the problem in Western Australia's property sector alone is significant. CoreLogic data shows WA had more than 34,000 properties listed for sale or rent in the first quarter of 2026 — a record for the state. A substantial proportion of those listings, particularly in high-turnover rental corridors like Cannington, Bentley and Midland, cycle through the same half-dozen interior photography packages. Property management firms operating across multiple Metronet corridor suburbs routinely republish the same bathroom and kitchen shots across different unit listings within the same complex.

For retail, the problem is compounding. Osborne Park's strip of auto parts, homewares and trade supply businesses has seen rapid e-commerce adoption since 2022, but many operators uploaded product catalogues without image deduplication processes. A single SKU appearing under three category pages with the same image file and no unique alt-text is, from a search engine's perspective, three weak pages competing against each other.

What Businesses Should Do Now

The fix is technical but not expensive. Image deduplication audits — running a site's visual assets through tools that flag pixel-level or hash-based matches — typically cost between $300 and $1,200 for a small-to-medium business site, based on pricing disclosed publicly by Perth-based digital agencies including several operating out of the Spacecubed coworking hub on St Georges Terrace. Larger operators, including local government economic development portals and state agency sites, can run automated audits through platforms like Screaming Frog, which flags duplicate image URLs as part of a standard crawl report.

The State Government's Small Business Development Corporation, which operates a business advisory service out of offices in the CBD and regional hubs, has not yet listed image deduplication as a formal advisory topic — but its broader digital health check program, available free to eligible WA businesses, covers website technical audits that can surface the issue.

The practical bottom line: every duplicated image on a commercial website is a marginal drag. Individually, the effect is small. Across 200 product pages or 50 property listings, the cumulative suppression on search visibility is measurable and, importantly, fixable before the spring property season peaks in September. Perth businesses that audit now are buying themselves a quarter's head start.
