My Dad taught me to sell, in the days before computers, but what he taught me still applies today.
Don't focus on selling something. Instead, find out what it is that your contact needs (I don't call them customers at this point). Then offer to help solve that need. And hey, sometimes your contact needs something that your competitor offers instead of you. But they will remember that you were honest with them.
Nobody wants to buy from you. But everybody has something they need. In your case, you are looking for people who need a good SEO blog.
And keep in mind that you're going to hear "no" ten or twenty times before you hear a "tell me more". And it might be twenty or twenty "tell me more" before you hear a "yes". Don't get frustrated.
