Text/headline/link description tips

• Keep text short, clear and to the point. People on Facebook and Instagram feeds scan very quickly. In fact, they spend on average 1.7 seconds with a piece of content on a phone, compared to 2.5 seconds on a computer. Learn more
• Explore different selling techniques or persuasion tactics in each asset you upload, so you know what you're comparing. For example, if you use several similar headlines, it might not be clear why some are high-performing.
• Use multiple lines of text as an easy way to get started with dynamic creative, if you don't have lots of image and video assets.

Image tips

• Focus your image message using our Six image ad tips and Tips for creating ads with a single point of focus as a starting point.
• Adding movement to images can make them more attention-grabbing in feed. Try these free, easy-to-use apps:

  • Hyperlapse - time-lapse video
  • Boomerang - looping video
  • Legend - quickly animate text
  • Videoshop - easy video editor
  • Adobe PhotoShop Express - intuitive photo editing
  • Adobe Spark - build videos from templates with text, images, photos and narration

• Avoid text on your images if you can. Use the text/ headline/link description fields instead. If you must use text on your image, try a smaller font and fewer words to lower the proportion of text to image. Our text overlay tool will help you ensure that your ad is approved. Learn more

Video tips

• Capture attention quickly by starting with the most captivating elements and/or showcasing your brand identity within the first three seconds. You could also consider trimming your video. We have found that videos of 15 seconds or less drive higher completion rates. Keeping your video ads at 15 seconds or less makes them eligible for Instagram Stories and Facebook in-stream placements, as well.
• Design for sound off, but delight with sound on. About 70% of mobile video watching in feed is with sound on (Facebook internal data, 2017). However, there are situations where people choose to watch with sound off, such as in a public place. To design for sound off:

  • Tell your story visually.
  • Use text and graphics.
  • Try captions (either with auto-captioning tools or an SRT file).
• Frame your visual story by using a vertical or square aspect ratio. This is because most people hold their phones vertically, so you'll cover more of their screen. We recommend 4:5 vertical video ads because they work well across most placements on Facebook, Instagram and Audience Network.
• Play more and experiment because we're all still learning what video content works well on mobile feed!

Call-to-action (CTA) button tips

• Use multiple CTA buttons to find out which are effective in getting people to take action. What do you want people to do after seeing your ad?
• Use dynamic creative in combination with our analytics tool Pixel to track results. Facebook pixel helps you understand the actions that people are taking on your website.
