Performance — How much does the widget weigh? Does it affect Core Web Vitals?
Pricing — Is there a free plan? What does the paid plan include?
Setup complexity — How long does it take to install and configure?
Customization — Can you match the widget design to your brand?
Privacy compliance — Is the tool GDPR compliant?
