which one is more improtant? internal or external link?

[anny feng]

There are both internal link and external link for a website,but which one is more important?and it is common to see a site with good content and internal links but less traffic.
so IMO, the external links are much more important for a site,
and you?

[Seogary]

good question!

[surreality]

That doesn't necessarily mean that external links equals good traffic, you know. Perhaps in your example it just so happened that the sites you saw with internal links simply didn't know any SEO and SEM techniques.
