How much should a small business spend on Google Ads?

Start from the numbers that matter

• Customer value: the average profit from a new customer, ideally over their lifetime with you.
• Close rate: how many leads become customers.
• Affordable cost per lead: the most you can pay for a lead and still make money, given your close rate.
• Conversion rate: how many clicks become leads on your landing page.
• Cost per click: what clicks cost for your keywords and area. Google’s Keyword Planner gives estimates.

A simple budget formula

Monthly budget = leads you want × (cost per click ÷ conversion rate)

Say you want 20 leads a month, clicks cost about $8 and your landing page converts 10% of clicks into leads. Each lead costs about $80 ($8 ÷ 0.10), so you need roughly $1,600 a month. If 1 in 4 leads becomes a customer worth $1,500 in profit, each customer costs about $320 in ads, which is affordable. If the numbers don’t work, improve the conversion rate or close rate before raising the budget. These figures are an illustration; use your own.

How Google Ads budgets actually behave

Google’s help page on managing spend explains that you set an average daily budget. On any given day, spend can be up to twice that amount, but your monthly charges won’t exceed the daily budget multiplied by 30.4, the average number of days in a month. So a $50 daily budget means up to about $1,520 a month, with some days higher and some lower.

Where to spend first

1. Your brand name, so competitors can’t take your own searches.
2. High-intent service searches such as “emergency plumber near me” or “estate planning attorney [city]”.
3. Your most profitable services, before broader or research-stage searches.
4. Remarketing to people who visited but didn’t contact you, once the basics are working.

A budget spread across too many campaigns learns slowly. Concentrate it where buyers are closest to deciding.

When to increase or cut the budget

• Increase when campaigns produce customers below your affordable cost and are limited by budget.
• Hold while you fix tracking, landing pages or wasted search terms.
• Cut or pause campaigns that spend without producing leads after a fair test, and move the money to what works.

Give changes time; campaigns often need a few weeks of data before results settle.

Budgeting across platforms

• Local Services Ads use an average weekly budget, and you pay per valid lead rather than per click. Google explains the details in its help page on how leads work.
• Meta ads (Facebook and Instagram) usually work best for reaching people before they search, and for remarketing to past visitors. Budget them separately and judge them on cost per lead, not clicks.
• Keep a testing reserve. Set aside a small share of the budget to test new keywords, audiences or offers without risking what already works.

Management fees and ad spend

Ad spend goes to the platform; management is a separate cost. At Ai Boutique, ad budgets are paid directly to Google and Meta from accounts you own, and ad management is included in the Pro and Max plans. Whoever manages your ads, make sure the accounts are in your name.
