Which produces better results?

What do you think- organic or paid? What kind of results have you witnessed for each?

This question may be too general to get a very detailed response. Organic or paid? Why is it either/or? Why not both?

what are your goals for the site?

[JS_Harris]

When you say "organic or paid" the answer will always be organic(free), why pay for what can be had for nothing?

As a webmaster however it would be wise to at least investigate both individually. Organic is a no-brainer but can you make "paid" turn a profit?
