About Michael
Michael Costin is an Australian digital marketer and entrepreneur who has worked across SEO, Google Ads, conversion rate optimisation and lead generation since 2009. In 2015 he co-founded Local Digital with Dominic Sergi, growing it from a two-person operation into a full-service growth marketing agency with offices in Parramatta, NSW and Burleigh Heads, QLD. He also founded Postclick, Local Digital's sister brand, which builds done-for-you lead generation funnels, landing pages and websites for home service businesses.
He got his start in June 2009 at Acorn Rentals, a Sydney car rental company, moving from marketing assistant to online marketing and business development manager. There he ran all of the company's digital marketing nationally, including a website redesign and relaunch, SEO, link building, PPC and email, and ranked the rebuilt site first for target keywords like “courtesy car”. Watching Google respond to the work was addictive, so in September 2012 he moved agency side to APD, one of Australia's leading digital marketing agencies at the time.
At APD he worked as an SEO executive and then SEO/CRO consultant on search and conversion projects for blue-chip brands, charities and large ecommerce sites, including eBay, Harvey Norman, iiNet, Suncorp Group, Unicef, The North Face, Rebel Sport and Chemmart. He also drove the agency's conversion rate optimisation offering: strategy, tooling, CRO and UX training, audits and testing across multiple clients. Along the way he built a network of affiliate websites that used SEO to attract more than a million visitors a month.
Since July 2021 he has co-hosted The SEO Show with Arthur Fabik: a weekly Australian SEO podcast that has passed 130 episodes, ranks among Australia's top 10 marketing podcasts, is heard in more than 100 countries and was nominated for an Australian Podcast Award. His work has been featured on Backlinko and Apple News, and Local Digital was named Best Large Integrated Agency at the 2022 APAC Search Awards.
Michael is based on the Gold Coast and splits his time between there and the agency's Sydney office.
