Why Are Images Important in Social Media Marketing?

A relevant image can stop the scroll, introduce the topic and encourage someone to read the post.

This matters because digital readers often consume only 20% to 28% of the words on a page. Most people scan first. They look at the image, headline and opening sentence before deciding whether to keep reading.

The Image Makes the Introduction

Your image is often the first introduction to your message. Before someone reads the caption, they may decide whether the post feels helpful, relevant and trustworthy.

Buffer found that Facebook image posts earned 35% more engagement than text posts and nearly 44% more than video posts in its analysis.

I think we sometimes spend so much time writing the post that the image becomes an afterthought. But if the image is what people notice first, shouldn’t we give it the same attention as the words?

What Should the Image Include?

Check this data out - Stock photography produces diminishing returns because consumers filter out obvious ads. Images featuring a real person in a recognizable, real-world situation (e.g., a real financial advisor speaking across a desk, a contractor inspecting a roof, or a founder working in their workspace) build immediate context and trust.

For those of us who have to use a "stock" image here are some tips for how we can recreate so it will get noticed.

• Isolate & Replace Backgrounds: Use Canva’s BG Remover to cut out the subject from a generic stock background. Place the subject into an environment that reflects your actual workspace, brand colors, or a localized setting.

• Incorporate Authentic Brand Elements: Add subtle brand assets such as your real logo on a product, a branded color overlay, or custom graphic framing to instantly signal that the image belongs to your company. BE careful with this one because placing a large, loud logo directly on an image signals "this is an advertisement," increasing the likelihood that users will scroll past. So instead add the logo on a shirt or coffee cup.

• Crop for Realism: Stock images often default to wide, sterile studio framing. Use tight cropping to direct focus to a single, human action (e.g., hands reviewing a document, a close-up of a tool in use) rather than the staged pose.

• Apply Consistent Filters/Toning: Create a unified visual identity by applying a standardized filter, adjusting warm/cool tones, or adding a light gradient overlay so all graphic assets share a cohesive aesthetic.

• Overlay Contextual Text: Keep text short (5–7 words max) using clean typography with strong color contrast. Place text in low-detail areas of the image to avoid obscuring the main subject.

Give Your Words a Better Chance

The image opens the door, but your message still has to earn the reader’s trust. Before posting, look at the image for two seconds.

Can you tell what the post is about? Does it connect with the people you serve?

If the answer is yes, the image is doing its job.
