I can speak from experience as I run a small agency, and live in Sydney, Australia. My clients are all within Oz. In late 2024 the helpful content algo destroyed a bunch of my local sites which were admittedly built with thin, mostly duplicate templated local geo pages, targeting every suburb across Sydney with 1 site, and Brisbane etc with other sites. I knew they were very grey hat, but they were working so I left them. First mistake... I got hit, those sites went from top of page 1 to page 7 or worst. Followed closely by angry emails and phone calls from clients. For the next "many months" i deleted and or redirected hundreds of pages on each site, painfully.. What i learned, never emulate this dated method, even if its a plumber site in Sydney, are you really going to be able to make each suburb page 50% different to the next suburb page, across 300 suburbs, with unique "real" images on each page, talking about the same plumbing specific service ? I'd say definitely not. I've spoken with a few leading SEO's at seminars etc regarding this since the 24 helpful content, and they agree that building out hundreds of local pages to blast a city is a thing of the past.. What works now is with Sydney in mind, there is Northern Beaches, North Sydney, Eastern Suburbs, Sutherland Shire, Macarthur District, Greater Western Sydney as regions of Sydney, build a page for each of these, sprinkle in a few of the sought after demographic suburbs within that region by mentioning specific landmarks, etc. Or what i do which I think is much better, is build "project pages", showing before & after images of a job in a particular suburb, i add a brief description of what the jobs purpose was, what the client requested, the product or service used to achieve the desired request, and even give the street name and suburb, highliting a landmark, eg- "X plumbing service at X restaurant, on Macquarie Rd, Sydney just 50 mtr walk from the Sydney Opera House. Sorry for the rant, but I really got stung in 24, and I don't want to see any of my new community go through same thing.
