Go for synonyms that job seekers eat up: Security, stability, successful, financial security. 'Opportunity' is a great buzz word. Phrasing? Whee to begin, "build a stable and successful career" "opening doors to sucessful careers" "find stability in an unstable world (market)" "Develop your own lasting career" Don't try to make it sound like a solution in a bottle, they don't exist. Make it seem like a guide to self satisfaction. That you can lead people in the right direction, that you have industry secrets that people need in order to get ahead in an inundated marketplace.
You can't MAKE anyone successful, you can show them the path though. It's the old 'leading a horse to water' routine.
You don't want to sound like some sort of two bit dog and pony show.
(wow all this talk of horse and ponies, how can you tell I'm Jonesing for the track! Two weekends away is killing me, I'll be near Seattle on the weekend, must find a little Emerald Downs time somehow; sorry, thinking on the keyboard again).
anyway,
The key here is to identify and answer people's needs. When you are unemployed, what questions do you ask yourself? What do YOU seek out in an advertisement or employment opportunity?
What makes you go, 'yeah, sure' and turn the page?
If yuo are planning on mass marketing your website, paid positioning, spamming email etc. You can go in with the hard close, make money now, 'click here immediately' 'you could be making money as you read this'...etc.
If you are planning on working the slow and sure route of proper web positioning, keyword weighting and tag balancing for individual search engines, target your audience by identifying their needs first and be very careful in your phrasing to not sound two-bit.
