In digital marketing, a landing page is a standalone web page, created specifically for the purposes of a marketing or advertising campaign. It's where a visitor "lands" when they have clicked on a Google AdWords ad or similar.
Landing pages are designed with a single focused objective – known as a Call to Action (CTA).
This simplicity is what makes landing pages the best option for increasing the conversion rates of your Google AdWords campaigns.
To fully understand the difference between a landing page, and the other pages on your website, such as your homepage, it's important to consider the differences between organic search traffic and paid search traffic.
