THE CHALLENGE
A Great Plumber Stuck
With Bad Marketing
How was it possible to nearly double the lead volume when their previous marketing agencies had said that they were maxed out and could not get more than 500 calls per month?
Lithium saw the opportunity. With the right SEO strategy and conversion-focused PPC campaigns, we knew Sarkinen Plumbing could grow far beyond what they’d been told was their ceiling.

AI SEARCH DOMINANCE
Winning the AI Search Revolution
Google’s AI Overviews now appear at the very top of search results — before ads, before organic listings. When someone searches for a plumber, Google’s AI recommends Sarkinen first.

AI SEARCH #1 RANKINGS
That’s 44 different searches where Google’s AI recommends Sarkinen Plumbing before showing any ads or traditional search results. While other plumbers are fighting over ad clicks, Sarkinen is getting recommended by AI — for free.
This is the future of search, and Sarkinen is already there. Their content strategy isn’t just built for today’s Google — it’s built for the AI-first search landscape that’s rapidly replacing traditional results.
PPC RESULTS
Google Ads Conversion Rate
Sarkinen had always been told that they needed to just keep spending more on Google Ads to increase calls. We took a different approach.
You don’t need to always increase the budget — often the best ROI is by increasing the conversion rate (CRO)! An average Google Ad campaign converts at about 5%. With CRO we were able to bring that to over 25%!
