Why is a landing page important?
A landing page is the first page that visitors see when they click on an ad or search it in search engines, which is obviously very important for conversion.
A good landing page must contain the information that conveys the offer, the related offers, the pricing, the benefits of the product, etc. in an attractive manner.
The purpose of a landing page can be a lot of things, such as a simple registration form, a survey, a 'thank you page, a download page, a subscription page, etc.
The idea behind a landing page is to help you convert people from one stage of the funnel to the next by giving them the information they need to get there.
The best landing pages typically have a simple message, a clear call-to-action, and a limited number of fields to fill out.
