# Block JavaScript disabled browsers

JavaScript is an online scripting language used extensively by websites and a lot of essential site functions are based on JavaScript code.

In order to save resources, some automation tools or low quality users may disable JavaScript. This action will also block different elements on the website that include tracking cookies and the user experience will be affected.

Depending on how your website is built, a user that disabled JavaScript usually will not be able to view much of your website or interact with it as it very possible that visual elements will not show or maybe the user will see a message asking them to enable JavaScript in order to continue.

In other words, if someone disabled JavaScript when visiting your ads and landing pages, they are probably not interested in your website's content and what you have to offer, thus wasting your marketing budget.
