The best LinkedIn profile advice to keep in mind is that Keywords are the key.

Search engine optimisation is all-important. Basically it means incorporating key words into your profile to ensure that when people are searching under those terms, your name comes up first. You need to list the skills and accomplishments you want to highlight as close to the top of your summary as you can get them. Think about the types of words your potential employer will search for and then pack them in accordingly. The more you use, the better your chances of success.
Get connected.

There are a myriad of ways to use LinkedIn which is why it’s so important to get good LinkedIn profile advice. Make sure you utilise every last one of them to improve your chances at finding a job. Update your profile regularly. Make connections with past and present colleagues. Join groups and take part in discussions. Get recommendations from trusted people you know. Call on the experts in your industry for advice. You can even keep all your online professional interactions in one place by linking your Twitter account, blog or website URL to your profile.
