Why this one is here
Not every account is a monster
Most of the case studies on this page are scale stories. This one isn’t — on purpose. Scot runs 4M Rentals out of Portland, Tennessee: family-operated, dumpsters from $340, porta johns, a service area that runs Gallatin to Springfield. His ad budget is about $500 a month. If that sounds like your account, this is your case study.
What we walked into
846 cheap clicks that weren't cheap
The account opened in May 2025 and ran about eight weeks of DIY before we got the keys — including a campaign that bought 846 cross-network clicks at $0.34 apiece. Cheap clicks aren’t cheap when they’re the wrong ones.
We took over at the end of June 2025 and replaced everything with one campaign: Adimize-Dumpster Rental Services, with a $50 CPA target written into the name so nobody forgets what the job is.
The numbers
Every quarter since takeover
| Quarter | Leads | Cost/lead |
|---|---|---|
| Q3 2025 (ramp) | 28 | $68.67 |
| Q4 2025 | 27 | $48.53 |
| Q1 2026 | 26 | $54.92 |
| Q2 2026 | 24 | $52.35 |
| Q3 2026 (thru Aug 19) | 18 | $42.65 |
Engagement to date: $6,685 in, 123 leads out, $54.35 a lead — trending down to $42.65 in the current quarter. The conversion rate tells the tuning story: 1.8% in month one, 18.9% in the latest month. Same budget, better machine. one campaign, 99.9 optimization score, 98% of spend on mobile — dumpster rental is a phone business.
The months we’re not hiding
September 2025 ran $133.59 a lead and January 2026 ran $183.61. Dumpster demand breathes with the seasons in Tennessee. Those months are real, they’re in the table’s totals, and they’re in every dumpster account you’ll ever own. The measure of a build isn’t whether winter happens — it’s whether the year lands under target. This one does: $49.60 over the last six months against the $50in the campaign’s name.
What it buys
What $50 buys here
A lead against rentals that start at $340 and run to $900. We don’t publish return math — conversion values in this account aren’t tied to booking revenue and we don’t pretend otherwise — but the arithmetic isn’t hard, and Scot keeps spending the $500.
Methodology
Where every number comes from
Figures from account-level Google Ads exports for the account Adimize manages (monthly cost and conversions plus the full campaign list; May 2025 – August 19, 2026, pulled August 19, 2026), reconciling to the penny: the campaign-list total equals the time-series total at $7,208.35. We took over at the end of June 2025; the engagement tables start July 2025, and the $166.24 the new campaign spent in late June sits between the eras and is disclosed here rather than counted. “Leads” are conversions as tracked in this account. Trailing-six-month figure covers March – August 19, 2026 (52 leads, $2,579.31). Rental pricing is from rent4m.com as of August 19, 2026. No revenue or ROAS claims.
