I find a lot of people belonging to the same marketing niche as me. How do I get them to my blog? Can I write a random person from the same niche a message to invite him or her to my profile where I announce my blog posts in status updates in social networks like Facebook? Is it spam? If not what should I write them? Can I send the same message to many random people interested in my niche? What to do next and what to expect? I don't want them to be my business partners - I just need blog readers. Do you have an experience like this? Please, share. Thanks!
