How Much to Spend on Google Ads

Work backward from the customers you want instead of picking a number and hoping. The most common question we hear is “what should I spend?” The honest answer depends on three numbers you can estimate yourself: how many new customers you want, how many leads it takes to close one, and what a lead costs in your market.

Step 1: Start With Your Sales Goal

How many new customers or jobs do you want from Google Ads each month? Start with a realistic number.

Step 2: Know Your Close Rate

Out of every 10 leads, how many become customers? If you close 3 of 10, your close rate is 30 percent.

Leads needed = new customers wanted ÷ close rate

Step 3: Estimate Your Cost Per Lead

Cost per lead depends on what a click costs and how many clicks turn into calls or forms.

Cost per lead = average cost per click ÷ conversion rate

Google Keyword Planner shows estimated click costs for your services and area. A well-built landing page with tracking in place helps your conversion rate.

Step 4: Do the Math

Monthly budget = leads needed × cost per lead

Subheading:

  • Goal: 6 new jobs per month
  • Close rate: 30 percent, so 20 leads are needed
  • Average cost per click: $6
  • Conversion rate: 8 percent, so each lead costs about $75
  • Budget: 20 leads × $75 = about $1,500 per month in ad spend

Then check it against what a customer is worth. If an average job brings in $2,000 in profit, spending $250 to get one customer is a strong return.

Tips Before You Launch

  • Set up call and form tracking first. Without it you cannot see your cost per lead.
  • Start with your most profitable services and your core service area.
  • Add negative keywords to block searches for jobs, free, DIY and services you do not offer.
  • Give a new campaign time to learn. Judge results after 60 to 90 days, not the first week.
  • Budget too small to get steady leads? Narrow the area or services before spreading it thin.
