A landing page is a stand-alone web page designed expressly for a marketing or advertising campaign in digital marketing. It's the page on which a visitor "lands" after clicking the email link or an advertisement from Google, Bing, YouTube, Facebook, Instagram, Twitter, or any other comparable website.
Landing pages are created with a single focus or goal, known as a call to action (CTAs), as opposed to web pages, which typically have multiple goals and encourage exploration.
