Many job board owners struggle with creating content. But I have always had luck getting it from other people. Namely users and people in my social networks.
So here’s the idea. Use the free Google Forms service to survey your registered seekers and candidates. Google Forms, which is part of the Google Driver service (for gmail users) is a an excellent tool to collect content. I am currently using it to conduct a survey of recruiters and will use their answers to write a blog post about what they will be doing differently in 2018 to recruit talent.
All it requires is for you to come up with some questions. Google Forms lets you add all types of question from multiple choice to long answers. They even let you upload files and store them for you.
Other ideas for this could be a contact form or even a job description page that lets you apply. You can upload your logo, change colors and make it your own.
