It is a page where you want to highlight something in particular, whether it is a product or something new, the CTA (Calls to action) and the contact form stand out. All design elements and content are oriented towards a specific objective.
The great advantage offered by landing pages is the ability to direct the user to a site where they can see the relevant and necessary information to complete the purchase of a product or service. In general, they are not accessed from the website, but their url is shared through social networks, newsletters and paid advertisements.
