I am a bit of confused about internal and external links. Basically I am designing my SEO.
So what is the basic difference between internal and external links?
When you link your pages within your own directory tree limit, is called Internal Link. While a user browsing your website, the browser is already in your directory, then you can point links from the current directory and don't need to specify a full URL path.
External links which link your pages to other web sites.
In order to create an external link to another web site, you need to know the other web site's URL with full path.
