What a $3,000 ad budget actually buys
Clicks, leads, customers and the maths in between — an honest walk through a $3,000-a-month campaign for a local B2B business.

“We tried Google Ads once. Spent a few thousand and got nothing.”
We hear that a lot. Usually the ads weren’t the problem. The problem was that nobody had worked out, before spending a dollar, what the money was supposed to buy, or set things up to measure whether it did.
So let’s do that maths out loud. Below is an illustrative $3,000-a-month campaign for a local business that sells something worth a few thousand dollars per customer: equipment rentals, trucking services, financing, renovations. The numbers are typical starting assumptions, not a client’s results. You can plug in your own on our ROI calculator.
Step 1: dollars become clicks
On Google Search you pay when someone clicks. What a click costs depends on your industry, your area and how many competitors are bidding. For our example, call it $4.50 a click.
$3,000 ÷ $4.50 ≈ 667 clicks a month
Those aren’t random visitors. On search, every click is someone who just typed something close to “chassis rental Surrey” or “equipment financing BC”. That intent is why search is usually where we start.
Step 2: clicks become leads
Here’s where most of the money is won or lost, and it has nothing to do with the ad. It’s about the page people land on.
A slow, generic homepage might turn 1–2% of visitors into enquiries. A focused landing page with a clear offer, a quote form and ideally something useful, like a payment calculator, can do several times better. For the example, we’ll assume 6%.
667 clicks × 6% ≈ 40 leads a month
At $3,000, that’s a cost per lead of about $75.
The cheapest way to halve your cost per lead is usually not a better ad. It’s a better landing page.
Step 3: leads become customers
Not every enquiry buys. Some are tyre-kickers, some are the wrong size, some go with a competitor. Say 15% close: 1 in 7 or so.
40 leads × 15% = 6 customers a month
How fast you reply matters as much as anything here. Leads go cold within hours, not days. That’s why we route every enquiry straight into your inbox or CRM, tagged with the ad that produced it.
Step 4: customers become revenue
If an average new customer is worth $3,500 to you, whether that’s a first invoice or the margin on a deal:
6 customers × $3,500 = $21,000 a month
$21,000 of revenue on $3,000 of spend is a 7× return on ad spend once the campaign is running properly.
The whole chain at a glance
| Stage | Assumption | Result per month |
|---|---|---|
| Budget | — | $3,000 |
| Clicks | $4.50 per click | ~667 |
| Leads | 6% of clicks enquire | ~40 |
| Customers | 15% of leads buy | ~6 |
| Revenue | $3,500 per customer | ~$21,000 |
| Return on ad spend | — | ~7× |
All illustrative. Your numbers will differ, and the point of measuring properly is to find out by how much.
Why month one doesn’t look like this
New campaigns need time to learn. Google’s bidding needs conversion data before it gets efficient, search-term lists need pruning, and landing pages need a round or two of fixes. In our model we assume the first month runs at about half efficiency and the second at three-quarters, before settling.
Over a full year, that ramp still leaves the example roughly $200,000 ahead after ad spend. But it does mean judging a campaign on its first two weeks is a mistake. It’s also why we insist on tracking before launch: without it, nobody can tell a campaign that’s learning from one that’s broken.
Small improvements multiply
Each stage feeds the next, so modest gains compound:
- Cut the cost per click 10% with tighter keywords: +11% clicks.
- Lift landing conversion from 6% to 7% with a better page: +17% leads.
- Close 18% instead of 15% by replying faster: +20% customers.
Do all three and the same $3,000 brings in about 56% more customers. None of those changes is heroic. Together they’re the difference between “ads don’t work for us” and a channel you’d happily spend more on.
Where the $3,000 should go
A sensible starting split for a local B2B business looks something like this:
| Channel | Share | Why |
|---|---|---|
| Google Search | ~45% | Highest intent: people actively looking |
| Meta (Facebook & Instagram) | ~25% | Reach and retargeting, great for lead forms |
| Performance Max | ~15% | Extends search across Google’s other surfaces |
| Retargeting | ~10% | Brings back visitors who didn’t enquire |
| Testing | ~5% | New keywords, audiences and creative |
That’s a starting point, not a recipe. After the first month, the data decides: money moves toward whatever produces customers at the lowest cost.
What has to be true before you spend a dollar
- Tracking works. Form submissions, calls and other key actions are recorded as conversions in GA4 and Google Ads, and every lead arrives with its ad source and click ID. Otherwise you’re optimising blind.
- The landing page is ready. Fast on a phone, one clear offer, a short form, and a reason to enquire today.
- Someone answers. Leads get a reply the same business day.
- You know your numbers. Roughly what a customer is worth and what you can afford to pay to win one.
What this means for you
A $3,000 budget can be a waste or a profit centre, and the difference is almost entirely in the set-up and the follow-through. Run your own numbers on the ROI calculator, then talk to us about building the campaign, the pages and the tracking to match.
