A big part of my job for one of my clients is to link build and i spend about an entire day each week trying to source and acquire quality links to their site. they are a good client and im keen to keep them and help boost their rankings in the serps with some good links back to their site but i get sick of 'begging' for links and most of the time getting ignored by people i email or pm. i know you dont generally just ask for a backlink and i do all the usual things to try and acquire links (create original content, write relevant articles, submit to as many directories as possible) but it still feels like its asking in disguise it seems like you turn over a ton of dirt to get one link (often a link thats not even worth that much). i spend time trying to build relationships with key people in the industry (using linkedin, twittering them or sending them an email) but 90% of the time i get no reply and i get the feeling they think im a spammer, which im not! i have quality content that i create and spend hours on, researching and writing. you get told that seo is all about content but it just doesnt seem to be working for me. has anyone had real success link building and if so what techniques did you use?
