- No profile photo. LinkedIn profiles with photos are seven times more likely to be clicked on than profiles without photos, according to Forbes.
- No recommendations. LinkedIn recommendations speak to what your colleagues think of your work and your networking skills. Be sure to ask anyone you've worked with -- and impressed -- for a recommendation. The worst that can happen is that they decline.
- Lying about skills. It may be tempting to fudge a few details about your knowledge, skills and abilities, but should an employer test you on one of these skills during the hiring process, your reputation is at stake.
- Bogus LinkedIn requests. LinkedIn offers several options to make a connection with another professional; one of these is, "I worked with [name] at [company]." Avoid using this option unless you really have worked with the recipient.
- Lots of recommendations all at once. This habit tips others off that you're looking for a job. It's far better to solicit LinkedIn recommendations on a regular basis -- after a project is completed, for example.
- Massive changes at once. As with the previous item, this signals that you might be looking for your next job. Make frequent small changes instead of infrequent large-scale audits.
