The harsh reality is that more often than not your proposal will not win the project during a Request for Proposals. You won't win 50% of the time, and you might not win even 25% of the time. If you don't have a thick skin when it comes to rejection you might want to consider a different business.
Lets be honest; when we write blog articles we do so because we want people to read them. And not just a few people, we want as many readers as possible. The challenge in today's online content realm is that you can't rely on your audience always coming to you, there are simply too many other things fighting for your viewers' attention. So instead of being reliant on your visitors coming to you, you need to incorporate strategies that push your content to your audience and, if they're interested, deliver your content to them whenever you publish.
