Maximise your employer brand before the job boards can!
Job boards just love the employer brand for a number of reasons. It makes their site look good with all of the logo's. They get lots of jobs/content to attract applicants with. And in most cases, they can use the employer brand name in their various marketing activities but in particular search engine marketing.
Now, I have just finished some analysis work for one of my customers and according to the reports (not 100% accurate but I'll 'moan' about this some other time) around 50% of applications come directly from the career site and 90% of online hires also come from the career site; job boards only delivered 10%! This is however an extreme as the norm is that job boards deliver 30-50% of online hires.
Laura Ries Blogs on The Origin of Brands about having focus when marketing using Apple and the iPod as one of the examples; showing how the whole company benefits from the major success of a key product.
So, my point is this....
Employers should focus more of their recruitment marketing cash on directing applicants to their career site in the most direct way possible. They should not allow job boards to hijack their applicants (read Joel Cheeseman about Yahoo views on this) or recruitment agencies to use their brand to attract applicants who end up elsewhere. They should make sure they have a robust and efficient online job application process, optimise their site and make greater use of search engine marketing (SEM).
Why? Because everyone else is and then charging the employer (a lot of money) for the benefit of having used the employers brand, to attract applicants, who then eventually get hired by the employer. But until they do, they'll have to carry on using job boards!!
