Can someone tell me how to get links for my website

Im looking to get links for my website can anyone tell me how to start linking to sites without getting permission
i need sites linking in

seriously...

SEO doesn't work like that, just getting random links to your website doesn't improve your rankings. You need to learn SEO strategy way before you start trying to build links.

I suggest you spend at least a few hours reading up on the forums sticky threads and learn the basics.
