About Dominic

Dominic Sergi is co-founder and Director of Local Digital, the growth marketing agency he started with Michael Costin in January 2015. Google Ads is his number-one game and driving ad-spend efficiency his aim, but he is equally at home across SEO, conversion rate optimisation, sales and business growth. If a business is struggling to generate leads and sales online, or finding its efforts are becoming less and less effective, he is the person clients call.

He started in paid search in April 2011 as a search executive at APD in Pyrmont, one of Australia's leading digital agencies at the time. There he set up and managed paid search and social accounts across Australia, New Zealand, the USA, the UK, Singapore, Japan, China, Korea and Germany on Google, Yahoo, Bing and Naver, with monthly spends of up to $250,000, for clients including Setanta Sports, Tourism Western Australia, GE Money, Visa, IKEA and Pepsi.

Promoted to account manager in 2013, he developed and executed growth plans across SEO, paid search, display and CRO for clients such as IKEA, Reed Exhibitions, IMB Building Society, Acer, Mirvac and The Heart Foundation, with a focus on cutting cost per acquisition while lifting conversion rate and return on investment. As senior account manager from mid-2014 he led a team of specialists and defined SEM, SEO, paid social, CRO and performance display strategy for blue-chip clients including NETGEAR, Tourism Western Australia, Chemmart, beIN SPORTS and Konica Minolta.

In 2015 he left APD to co-found Local Digital, growing it from a two-person operation into a full-service agency with offices in Parramatta, NSW and Burleigh Heads, QLD. Since July 2025 he has also worked as a conversion rate specialist at Postclick, Local Digital's sister brand, which builds done-for-you lead generation funnels, landing pages and websites for home service businesses.

Dominic holds a Bachelor of Economics (Banking and Financial Support Services) from Western Sydney University and has been Google Ads certified since 2011.
