you have to have a right approach before approaching for links...first of all identify the blogs in your niche or related niches by going through Google blogs, forums, technorati, blogroll, wefollow, search, competitor links etc , organize the contacts in spreadsheets with names,email,phone number, mozrank etc of the site, introduce yourself to the website or blogger,, establish relationship and give some kind of incentive to the blogger either with free promotions, offers, content etc and build relationship with the blog owner or website for long term and lastly they become your regular linkers to your campaign....repeat and rinse the process every month....
important thing to remember when approaching to blogger or site owner...be transparent, authentic, state your intent etc...follow them on twitter, comment on their blog etc....
