Call for more research on usage of employer rating sites

A few days ago I started a LinkedIn Poll on usage of review and ratings site, which basically looks like this:

In order to find out more about a prospective employer, when do you visit an employer review and ratings site?

*  Before sending off my application

*  After I've got invited for an interview

* After I've attended the job interview

* As soon as I receive the job offer

* Never

As long as the poll is active, you can see it in the right column of this blog. I look forward to the results. Thanks.

Out of interest I recently also checked German employer review site kununu.de to compare two companies, two established Internet Start-Ups, one in B2B, one in B2C field.

Results? The B2B company received nearly 60 ratings, while the B2C company only some 15. While the profile of the B2B company was viewed nearly 20,000 times, the profile von the B2C company has been opened nearly 5,000 times. The average rating of the B2B company was worst by around 0.3 percent point.

Is it possible, that

* the brand image of B2C company influences the perception of their employer brand and blocks job seekers to seek out more information about them .

* employer rating of B2B company are viewed more often because job seekers may not have any associations with the company

* The better brand image of the company, the less likely the employer brand will be explored via employer review site.

Or is the varying activity level of ex-/employees and job seekers on these two employer profile sites just a result of the time lag in their profile existence, information that cannot be obtained on the kununu-site. Nota bene, both companies have been heavily recruiting based on the number of job advertisements on their career sites and job boards in May 2012.
