Do you have a premium account with any of our free job board partners? If so, you can track how many applicants are coming to your jobs page by using tracking codes, nearly-invisible images that let you know how many applicants viewed each page.
To enable tracking, contact your account manager at any of these sites and get your custom tracking code. From there, select Configure->Job Board and select [Edit] next to External Job Board to paste in the custom codes!
Note: These instructions only apply to job board integrations options 1-4. Anyone using option 5 will need to configure tracking pixels on your job board manually.
