Your visual ads need to attract the attention of the user.
Make sure to use branding! For example your brand’s logo and colours. This will make sure people associate this ad with your company.
A call to action shows the user what the next step they should take is. For example, visit your website or blog.
Make sure you are speaking directly to the user. Understand the target audience and aim your advertising at them.
Make sure not to repost your ad too often as it can appear more as spam than useful . Be in control of how often your audience sees this type of advertising.
The brain responds to and processes visual information so much faster than text! Use imagery in your social media ads.
