A landing page is the page where a visitor is directed after clicking on a link or advertisement. The landing page is very important in Affiliate Marketing. When the visitor clicks on an advertisement on a publisher's site, it is important that the landing page meets the visitor's expectations. It is also crucial that any offers are immediately visible and that the page has a strong call-to-action.
In Affiliate Marketing, deeplinks are often used. Essentially, every product page is a potential landing page. Therefore, ensure that each product page meets the above requirements. This can greatly increase your conversion rate (and thus your success with Affiliate Marketing).
