As a busy sales professional intent on meeting your objectives, you might wonder if you can afford to consistently read sales blogs.

After all, each minute you spend on a post is a minute you could be connecting with a new prospect, coaching one of your salespeople on an essential skill, or developing a new qualifying framework that’ll help your company scale.

But the real question is: Can you afford not to read sales blogs? Whether you’re a rep, a sales manager or an executive, your ability to reach your goals grows exponentially when you incorporate others’ wisdom, experiences and strategies.

It might take you five minutes to read an article on giving great demos. The takeaways, however, might win you the deal. Five minutes for new business? Not a bad trade.

To help you find the sales blogs with the most valuable content, we’ve curated the following list.
