"How much should I spend on Google Ads?" There is no single answer — but there is a right process for finding yours. A budget that's too small leaves potential customers on the table; a budget without structure burns cash without results. Our paid search management services are built around making every dollar accountable.
Google Ads operates on a pay-per-click auction. Before setting a budget, know what clicks cost in your vertical. Industry average CPCs in 2026:
Legal: $6–$12
Financial Services: $5–$10
Healthcare: $4–$9
Home Services: $6–$15
eCommerce (Retail): $1–$3
B2B / Software: $5–$20
Travel: $1–$4
These are averages. Your actual CPC will depend on your Quality Score, ad relevance, and the competitiveness of your target keywords. See our guide on maximizing ROI on paid search campaigns for tips on lowering your CPC through better Quality Scores.
A reliable rule of thumb: your monthly budget should be enough to generate at least 100–200 clicks per month, ideally per campaign. Below that, Google's algorithms don't have enough data to optimize, and you won't have enough data to make decisions.
Formula: Minimum budget = target CPC × 150 clicks × number of active campaigns
For a business in a $5 CPC vertical running 2 campaigns, that's $1,500/month minimum just to collect meaningful data.
A common planning heuristic is to allocate 5–15% of target revenue to Google Ads. Higher-margin businesses (SaaS, financial services, legal) often justify 15–20% because a single converted customer has high lifetime value. Lower-margin businesses (retail, commodities) typically stay at 5–10%.
Don't pour everything into one campaign. A well-structured Google Ads account typically splits budget across:
Branded campaigns (10–20% of budget): Protect your brand name from competitors. These are cheap clicks with high conversion rates.
Non-brand/competitor campaigns (50–60%): Target high-intent keywords in your category. This is where growth happens.
Remarketing (20–30%): Re-engage visitors who didn't convert. Remarketing lists for search ads (RLSA) are among the highest-ROI tactics available.
The signal to scale is simple: when your campaigns are profitable and impression share is below 70%, there's uncaptured demand you're leaving for competitors. Scale budget in 20–30% increments, then monitor performance for two weeks before scaling again.
Whether you're starting at $2,000/month or managing $200,000/month, budget efficiency comes from structure, not spend levels. Get a free paid search audit and see exactly where your current budget could work harder.
