Set up Google Analytics: Start by creating an account in Google Analytics and linking it to your website. Make sure you install the tracking code correctly to collect data on site traffic, pages visited, dwell time, traffic sources, and more. This will provide you with valuable information about user behavior on your site.

Analyze key metrics: Use Google Analytics to analyze key metrics that will provide you with valuable information about the performance of your online marketing channels. Some of these metrics include organic traffic, conversions, bounce rate, time on site, and the device used by customers to access your website. 

These metrics will give you a clear view of how each channel is performing and help you identify areas that might require improvement. For example, if you see a high bounce rate on a specific channel, you may need to optimize the relevance and quality of the content to retain visitors and encourage engagement. 

Track conversions: Set up conversion goals in Google Analytics to track key actions that users take on your website, such as filling out a contact form, making a purchase, or subscribing to a mailing list. This data will allow you to evaluate the effectiveness of your strategies and determine which channels are generating the most conversions.

Have you used a CRM: In addition to Google Analytics, Customer Relationship Management (CRM) is a powerful tool to measure the performance of your marketing channels. Its main function is to record and analyze data related to your customers, such as their interactions with your company, the transactions carried out and their value for your business. This will help you better understand the impact of your marketing actions and make more informed decisions.

Remember that measuring your channels is not limited to just collecting data, but involves analyzing it and taking actions based on it. It's important to conduct regular evaluations of your metrics, identify areas for improvement, and adjust your strategies accordingly. By effectively using Google Analytics or CRM, you will be able to maximize the performance of your marketing channels and boost your online sales.

Please note that each company is unique and results may vary. We encourage you to experiment with different strategies and stay up to date on best practices in the field of data analysis and online marketing. Remember: measure, analyze and optimize to achieve success in your industry!
