Posting in groups and in your LinkedIn stream isn't just for recruiters - job-seekers can advertise what they're looking for as well. But it's important to stay away from the tired, stale terminology that most people use, such as this:
"I am a highly skilled, dynamic, and extremely motivated manager with extensive experience in the retail industry. If you are looking for a born leader who is resourceful and has exceptional communication skills, look no further. Check out my profile and contact me today!"
Posts like this don't attract attention because they don't say much. Let's look at it:
"...highly skilled, dynamic..."
When it's time to job search, trust me - absolutely everyone thinks they are highly skilled, dynamic, and much more. It means nothing because it's your opinion of yourself.
Yeah, because you're out of work and looking for a job - of course you're motivated. (But what happens once you GET the job?) Again, this is something that almost everyone says, and it means very little.
"...extensive experience in the retail industry."
What does 'extensive' mean - 30 years? 5 years? 6 months? It can mean something different to everyone.
"...a born leader who is resourceful and has exceptional communication skills..."
I think you're getting the point - if you can't prove it, don't bother typing it.
"Check out my profile and contact me today!"
Do you have contact information on your profile? My guess is maybe 1 out of every 10 LinkedIn members has contact information clearly listed on their profile.
My advice is this - provide recruiters with the information they're looking for, and you will attract their attention and make a strong first impression. Are they looking for someone who is highly skilled, dynamic, resourceful, etc? Yes. Will they believe that you are all of those things simply because you say you are? No.
What they want to know is this:
Recruiters need to know things like this to establish whether you're a viable candidate or not. Stating that you're motivated, resourceful, and dynamic doesn't tell them anything - you could be an assistant manager at 7-Eleven and be all those things, or you could be a regional VP at Costco and be all those things. Make it clear who you are, what you are looking for, and what you have to offer, and you will attract more attention. Here are a couple examples:
