What clients say

Real results from real clients.

“We'd tried three Google Ads agencies before OIESU. The difference is they actually understand property buyer intent — not just keywords. Within 60 days we had 86 qualified property enquiries per month at a cost we could sustain.”

MR
Michael R.
Director · Real Estate · Australia — NDA Protected

“OIESU cut our cost-per-lead by 41% in the first 60 days. Their Google Ads team understands legal advertising restrictions better than any agency we've worked with. We now have a consistent 90+ qualified consultation pipeline every single month.”

SK
Suresh K.
Founder, PPC Agency — NDA Protected, India

“We scaled from one practice to four locations in 18 months — OIESU's Google Ads strategy was central to that growth. Each location now generates 40–60 new patient enquiries per month at a cost per acquisition well below industry average.”
