(If you plan on using text in your image, Facebook has a very cool tool that will help you work around the 20% text overlay rule)
There's a lot of ad content on Facebook, and when Facebook users scroll through their News Feeds, that content start to blend together.

Let's say, for sake of this blog post, you're looking to drive more traffic to your website. When you select this option, Facebook will prompt you to enter the URL you're looking to promote. If you're using marketing automation software, be sure to create a unique tracking URL with UTM parameters for this to ensure that you'll be able to keep track of traffic and conversions from this ad. For HubSpot customers, this can be done using the Tracking URL Builder.
