How often you review your Conversion Rate Optimization (CRO) strategy will depend on several factors: traffic numbers, competitors, complexity of the project at hand, industry, shift in trends, and more. Typically, you must review your CRO strategy at least quarterly; however, high-traffic websites may need monthly assessments. If you notice sudden conversion drops or rises, or changes in business goals, an immediate review may be required. Also, if you're making major changes to your website in terms of design, content, and more, or running continuous A/B tests, monthly or weekly oversight could help identify opportunities and friction points more easily.
