I know link farm is not good for seo but Im confused
Is link directory similar to link farm?

I think a linkfarm only got links and a link directory got some more content of some kind.

What is much better link farm or link directory in terms of SEO?
Is link farm is releated in SEO and will it help you in making your PR higher?

Link farms are always bad when you talk about SEO. Link directories or link exchagnes with other related web sites are good things.

I agree with bylla. Link farms are considered as a black hat seo. You might be able to rank well for now but you will soon be banned.

Link directory is a list of links organized. User may find some useful information from link directory. But link farm is just a list of links created to get backlinks only. Do not get links from link farms. Google may ban your site.

Directories link and link farm are two common terms that are frequently used. Each of these processes has its own features but in terms of acceptability directories link or one way link is a better option that a user can option for.

But directories link or one way links are more beneficial for websites to get higher search engine rankings and greater visibility on the web than link farm.
