How to run Google Ads without hiring an agency

Most agencies charge between $1,500 and $3,000 a month to run Google Ads for a small business. For some businesses, that's the right call. For most, it's not.

Here's a framework that lets a small business run Google Ads competently without paying anyone a retainer.

Step 1: Decide what a customer is worth

Before you spend anything on ads, write down what an average new customer is worth to your business. Be honest.

A plumber's average customer is worth maybe $400 once you account for repeat work. A coffee shop's first-visit customer is worth maybe $8, but maybe $80 over a year if they come back weekly.

This number is the only thing that matters. Everything else flows from it.

Step 2: Set a per-click budget that respects that number

If a new customer is worth $400 and you expect roughly 1 in 20 clickers to convert, you can afford to pay up to $20 per click. If a new customer is worth $8 and 1 in 30 will convert, you can afford to pay $0.27.

That's it. That's the math.

If your industry's typical click cost is higher than what you can afford, Google Ads is probably not your channel. Try local SEO, organic social, or email marketing instead.

Step 3: Pick the right keywords

The cheapest, highest-converting clicks come from keywords with two qualities:

1. Local intent. "Plumber near me" beats "plumber" every time.
2. Specific need. "Emergency drain unblocking" beats "plumbing services" every time.

Generic, high-volume keywords are expensive and rarely convert. Specific, lower-volume keywords are cheap and convert often.

Step 4: Write three versions of every ad

Google Ads now uses what's called "responsive search ads." You give Google several headlines and descriptions, and it figures out which combinations work best. Don't agonize over picking the perfect one. Give it variety:

• One headline that mentions price
• One that mentions speed
• One that mentions a specific neighborhood or city
• One that mentions a guarantee

Google sorts out the rest within a week.

Step 5: Don't change anything for two weeks

This is the hardest step. You'll be tempted to tinker every day. Don't.

Google's algorithm needs about two weeks of data before it figures out what's working. If you change keywords, ads, or budgets every other day, you're starting the learning over each time.

After two weeks, look at what's working and double down. Pause anything that isn't.

What this looks like in practice

A coffee shop spending $300 a month on Google Ads, targeting people searching for "coffee near me" within a 1.5 km radius of the shop. They run two ads: one mentions "free Wi-Fi", the other mentions "best espresso downtown." After two weeks, the espresso ad outperforms by 2x. They pause the Wi-Fi ad and shift the budget to a third version focused on study spots.

That's the entire workflow. No agency. No retainer. About 20 minutes a week.

If you don't have 20 minutes a week, that's where a tool like ours comes in. The framework above is still the same.
