A lot of LinkedIn users that I see online have great profiles, with a few exceptions. Those exceptions are often the following. They’re weak in endorsements, recommendations, and/or skills. Often all three. It’s like these three are the step children of the various fields that make up a complete LinkedIn profile. Here’s why you don’t want to ignore these all-important parts of your LinkedIn profile.

Look at it this way. When’s the last time you bought something that cost more than a few dollars (or pounds or yen, etc.)? Being an Internet savvy person, what did you do? If you’re like most folks, you Googled whatever it was and read about what other people thought, right? Well, people are doing essentially the same thing on LinkedIn. We call this social proof in the marketing business. People are highly influenced by what other people think. Being endorsed is one of the ways of providing this social proof to people who visit your profile on LinkedIn. Recommendations are another way of providing this proof.

Have you ever asked a colleague about the car they just bought, the new restaurant they tried, or their dentist or doctor? For important purchases, finding the right product or the right service provider is often done through recommendations. Recommendations carry a huge amount of influence, and you should be asking the people you’re connected with, at least the ones you know well, to recommend you.

Finally, listing your skills matters a lot! Seeing a large list of skills along with the number of people who’ve endorsed you for them is a great way to position yourself as a professional. Not only that, but the selection of skills helps viewers get to know you. Both recruiters and people who are potential clients are going to scan these skills to help them understand who you are and what you bring to the party!
