Your logo is the face of your brand and should be used and placed properly in an infographic. Resist the temptation to splash it all over your infographic. It doesn’t belong at the top, as a watermark in the middle or anywhere it might fit. This approach will only make your content to appear sponsored or branded, and readers aren’t likely to trust it.
Your goal is to educate, inform or entertain your audience, not to self-promote. If you self-promote, your content credibility will drop by 29 percent according to a Kentico software study.
You can still add your logo, but place it at the bottom of the page instead of making it the first thing your audience will see. This will add credibility to the content of the piece and associate your brand with the integrity of the infographic.
