URL parameters are important because they can give us valuable feedback on which campaign, which creative content and which text was the one that was most interesting to a given audience, and generated the most revenue. Isn’t it great, that you can see exactly which post is the most or the least worth it?
The most important thing is to actually make use of the URL parameters in e-mail marketing campaigns specifically, or when posting on social media platforms. In the case of an e-mail based campaign you can measure which letters resonated with the target audience very precisely, or which specific picture or content drew the most clients to the website, and got them to become clients.
Have you ever forgotten to give parameters to a very important campaign?
