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. Facebook and LinkedIn each adjust and resize the images differently, so you may need to adjust your Job Board image so it will look good on both. LinkedIn uses a square image, roughly 250x250. Facebook prefers a rectangle that's 350x250, so you can try to resize your logo to fit in the intersection between them.
The ideal is an image that is 350x250, but with the total image area limited to a 250x250 square in the middle.
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.
