Conversion optimization for small business websites doesn’t require expensive software or huge traffic numbers. In fact, solo CRO freelancers and small agency owners working with startups, e-commerce shops, or local businesses often face limited traffic and no dedicated developers. That can make traditional A/B testing impractical – a classic A/B test needs a significant amount of traffic in order to provide beneficial results within a reasonable timeframe.
Don’t worry: there are alternatives to A/B testing that still yield insights on low-traffic sites. The key is to leverage a few essential (and free!) tools that are easy to install, even for non-technical folks, and that deliver immediate data for smarter decision-making.
Below we highlight three must-have free tools every conversion rate optimization (CRO) professional should install on every client’s website from day one:
- Google Analytics
- Microsoft Clarity
- Google Search Console
These tools provide a mix of quantitative and qualitative insights to drive organic growth and boost conversions quickly.
