Difference between external and internal links

[Maddy]

Are there any difference how Google ranks external and internal links.

Also with the anchor text, does Google put more weight on anchor text from external sites than internal.

I am wondering if I need to get bunch of sites to link to me, or if it is enough to build big, huge, tremendous site.

External links are commonly looked apon as more important than your own links, as the commonly that they are there suggests that some other website thinks your site is important abundant to link to it. Internal links are still useful to have though, as they can help you tell the web spiders what your site is about.

External links:
External links are hyperlinks that links between two different domains like domain A post their links on other domain is called, external links.
website A --Link--> website B
It play important role in improve your ranking, traffic and Pagerank because external links pass link juice, which are very beneficial to increase ranking and Page rank of your website.

Internal links:
Internal links are hyperlinks that point the links of same domain like internal sub pages links or deep links.
It helps to navigate the site and spread the link juice arround site.

Internal links are that you made on your website that lead to other pages of same website. They are called internal links. And the external links point to other pages of other sites.
