Return on investment in SEO is straightforward in theory: revenue generated from organic search minus the cost of generating it, divided by that cost. In practice, most locksmith businesses struggle to measure it because they never set up proper attribution before starting.
Let's anchor this to your actual numbers. If your average residential lockout job is worth $150 and your average commercial rekeying job is worth $400, a single organic lead that converts has very different value depending on the service. That's why a blanket "SEO costs $X per month" statement tells you almost nothing without knowing what kinds of jobs it's producing.
The cleaner way to think about locksmith SEO ROI is to ask two questions:
- How much does it cost me to acquire one customer from each channel I'm currently using?
- What is the lifetime value of a customer who found me through organic search versus a paid lead-gen platform?
In our experience working with local service businesses, organic search customers tend to have slightly higher intent than leads purchased from aggregator platforms — they searched specifically for a locksmith in their area, found your listing, and called you directly. That generally translates to a higher close rate on the call.
The ROI equation for locksmith SEO looks like this:
- Monthly organic leads × close rate = new customers from SEO
- New customers × average job value = monthly revenue from SEO
- Monthly revenue from SEO ÷ monthly SEO investment = gross ROI ratio
A ratio above 1.0 means you're getting more revenue than you're spending. Most established locksmith SEO campaigns, once rankings are stable, produce ratios well above that — but it takes time to reach that point, which we address in the timeline section below.
