When you create organic posts or Facebook ads for mobile, images and videos should cover as much screen as possible to grab attention. Also, you want to make sure your video/image is responsive on the mobile device, so the viewer has no problem watching it in its entirety no matter how they use the phone or tablet.

Choose the correct aspect ratio that best suits different placements and formats and remember to check which placements support which aspect ratios. Below are some recommended aspect ratios for different placements and formats across the Facebook platform (this includes Instagram too):

Research(1) shows that YouTube is where Aussie millennials go to make up their minds, to connect with the world around them, and or self-development. 
​
Aussie millennials, aged 26 to 40 (born between 1981 and 1996), have grown up in an everchanging world, and they’ve come to expect unprecedented access to information—wherever and whenever they want. Offering diversity of content and best-in-class personalisation, YouTube’s highly adaptable user experience and on-demand nature provides the sense of control that millennials crave.
YouTube is a big part of that world for both millennials and for the rest of Australia. Aussies of all ages are spending more and more time on YouTube, with over 15M Aussies spending more than 18 hours each on YouTube per month.

Research(1) shows that Aussie Gen Xers turn to YouTube to get things done, engage with their passions, and rediscover their childhood memories. What can your brand/business do to reach this unique audience?

Gen Xers, aged 40 to 55 years old (born between 1965 and 1980), grew up listening to Walkmans (I know I did☺), eating Neapolitan ice cream, and watching shows like Thunderbirds on TV — the only thing that was notably absent was the internet. Despite this, Gen X is embracing the multi-screen, multi-channel world that we know today. YouTube is a big part of that world for both Gen X and for the rest of Australia. Aussies of all ages are spending more and more time on YouTube, with over 15M Aussie adults spending more than 18 hours each on YouTube per month.
But what exactly are Gen Xers watching on YouTube? As a business owner, it's important that you understand the role the platform plays in their lives.
