One of the primary benefits of using edge functions is that they allow you to move certain processing tasks closer to the edge of the network, closer to the user. This can greatly reduce the latency that users experience when accessing your website, as their requests do not have to travel as far to reach the server that is handling the request. This can lead to faster page load times, which can improve user engagement and ultimately lead to higher conversion rates.

Another benefit of using edge functions is that they can help to reduce the amount of data that needs to be sent over the network, which can also lead to faster page load times. By performing certain processing tasks at the edge, such as image optimization or minifying CSS and JavaScript, you can decrease the size of the files that need to be transferred to the user's device. This can help to reduce data usage and improve the overall performance of the website.

In addition to these performance benefits, edge functions can also be used to improve the security of your website. For example, you can use an edge function to handle authentication and authorization tasks, rather than sending sensitive information to a centralized server. This can help to reduce the risk of data breaches and protect your users' information.

Overall, using edge functions such as Vercel can help to improve the performance and security of your website, which can lead to higher user engagement and ultimately result in a better ROI.

It's also worth mentioning that Vercel is a hosting platform which also support serverless functions that allow developer to run code on the edge and it support many popular web development frameworks such as Next.js and Gatsby. this make it a one-stop solution for web development, hosting and serverless functions.

If you're looking to improve the performance of your website and boost your ROI, consider using an edge function such as Vercel to handle certain processing tasks and protect your user's data.
