The Challenge

Buried on Page 3 While Competitors Owned the Map Pack

Denver Drain Masters had a solid reputation with existing customers but couldn't crack the first page of Google for a single plumbing keyword. Their outdated website hadn't been touched in 4 years. They had no GBP, no reviews, and were spending $800/month on Angi leads with a 35% close rate.

Page 3 Google for every target keyword — effectively invisible

!

No Google Business Profile — missing from Maps entirely

!

Zero online reviews across all platforms

!

$800/month on Angi with poor lead quality

Outdated website with no mobile optimization
