LinkedIn Profile for job seekers

So a colleague of mine recently asked for advise on how to setup their LinkedIn profile correctly to gain maximum exposure as an active job hunter, so here it is:

You should consider your LinkedIn profile your online resume. It should have all the same information that is on your resume including your qualifications, your experience, and your skills.

Professional Summary. 
The Professional Summary section of your profile is a good way to highlight your experience. Select an Industry, because recruiters often use that field to search. Don't forget the Headline, because that's right at the top of the page when someone views your profile. (Include Currently Seeking New Opportunities right at the top!)

Keywords and Skills. 
Include all the keywords and skills from your resume in your profile. That will make it easier for your profile to be found in search results not only from LinkedIn Searching but through external search engines (Google, Bing, etc.)

Contact Settings. 
Let your connections and the public know what you're available for. Options include: career opportunities, consulting offers, new ventures, job inquiries, reference requests. 
Include your contact details (Mobile, Email, etc)
Set your profile to visible to all which will allow everyone to see your profile in full and contact you. (You can always switch this back to Network only when required)

Groups:
Join relevant business groups as they hold a wealth of information, networking opportunities and jobs that never go to market as the group members recommend or apply directly (The client can post jobs for free in groups)
