Monitor website traffic, conversion rates, and sign-ups to assess user interest and adoption. Additionally, use analytics tools to analyze user behavior, conversion funnels, and referral sources. Gathering feedback and testimonials from users can also provide insights into the impact of your launch. By measuring these factors, you can evaluate the effectiveness of your launch and make informed decisions for future improvements.
