What is splitting of links?

[displaybanner]

I read in an article that one should avoid splitting of links.
Links that come from outside shall have same url as internal links of the same landing page.
What does that mean?
I am quite confused.

Splitting of a link means that links should point to to the same url than the index page name and others to the directory root.The splitting of link can happen when you have two different versions of the same website.Disadvantage of the this splitting link iswhich does not redirect visitors to the proper location.
