Methods

Is there a way to figure out a link building method that a site is using? I know of a site that is 2 years old with over 1 million links. How is that even possible? I am a 'newbie' so go easy on me if this is a dumb question.

mostly free services offer to show only 1000 back links

but as u said 1 million links

u have then two options

1- Buy xumer and scrap box softwares and blast link building

2- Or choose long tail keywords for ranking easily high in search engines
