Definition: Each page on a website has a unique internet address, called its "URL" (Uniform Resource Locator.)
Pages on websites are connected to other web pages by "links" to the URLs for other pages within the website, or to pages on other websites.
When your website is linked to by another website it is called an inbound link. When you link to another website, it is called an outbound link.
Many search engines use the number of inbound links as one metric for how popular a website is. But the wrong kind of inbound links, or inbound links obtained using "blackhat" strategies can lower page rank or even cause a website to be delisted from search engines.
Also Known As: Inlinks
