This is a topic with a lot of relatively new trends.  For example, Linkedin isn’t that old of a company and advertising on its platform is an even newer concept.  Companies are just now figuring out ways to make very optimized ad campaigns on the site to create a justifiable return on investment.  The same thing goes for Google AdWords.  While the platform has been available for a while now, the process for optimizing a campaign has evolved a lot and companies are only now figuring out the best practices.

With that being said, there are a few resources at your disposal that can really help you out if you would like to read and learn more about the topic.

Most people think of the front page of Reddit, but there are some very informative subreddits tailored to a very specific audience.  This is especially so for the Sales subreddit.  While it is not specific to IT, you can learn a ton from an amazing community of sales professionals on this site.  If you have any question about your sales process and/or want to get other people in your industry to review you sales plan and what you have been doing, this is the place to be.  The members of this community will be very direct and will not sugarcoat anything, so you know you will get the best feedback possible from any questions that you have.

This is kind of a similar resource to the Sales subreddit.  You can pose a question to the Yahoo Answers community and you will more than likely get a really informative answer from someone who is in the business.  You can then look at other related questions that people have asked and learn from the answers to those questions.  You would be surprised by how informative Yahoo Answers can be if you ask the right questions and if you do the right research.

This is a blog that details the day-to-day of an IT salesman.  You can get some really good ideas on how you should go about sales if you too are an IT salesman.  If anything, this is a good site to read to just brainstorm on how you can improve at your job.  It is good to read how other people are going about their job to reflect and see if you think you could do anything differently to improve at your job.  Overall, this is a very good resource.
