Using LinkedIn and Facebook to promote your jobs is a great way to mine your social circles for hidden talent, but sometimes the posts don't look quite the way you want them. Luckily, anyone hosting job descriptions on their own site can configure things to look great!
Facebook and LinkedIn use something called the Open Graph Protocol to determine what content gets pulled when a link is posted. There are lots of optional ones, but the areas you will likely care about are:
- og:type - website
- og:title - Come work at Greenhouse!
- og:description - "At Greenhouse, we love hiring so much..."
By configuring this metadata in the head of the page that hosts your job board, you can determine what gets pulled in. If these values are missing, social media sites will simply use the title of the page and the first image it comes across, regardless of quality. If you have any issues with Facebook, you might want to check these two pages that offer help on how to set things up.
For companies who don't host their job descriptions on their own sites, the options are more limited. The company logo that you upload from the Configure > Job Board > Edit Job Board page is the logo that will be used when you share jobs on Facebook and LinkedIn. This article goes over in great detail about the optimal image sizes for different Social Media including Facebook and LinkedIn. For this logo file, the best image size that will work with both Facebook and LinkedIn would be 1024 x 512 pixel image.
Please note: LinkedIn caches the photo and description previews, so even if you make a change, it may not appear until 7 days after the link was originally posted. After this time, LinkedIn will check the page again and pull over any new information.
