1. Lists

Upon reviewing random list-type articles ranking in the top 3 on Google, I noticed the average text-to-image ratio is one image per every 133 words.

A handy guideline is one image per list entry.

For a top 10 list, incorporating 10 images is ideal.

However, not every list article follows this rule.

Some had only a single image throughout.

Key Takeaway: Using one image per entry is a reliable approach for list articles.

2. How-To Guides

Examining various how-to guides ranking in the top 3 on Google, I found there’s typically one image for every 179 words.

How-to guides generally have fewer images than lists, but still a significant amount.

This makes sense because visuals greatly assist in teaching.

Key Takeaway: In how-to guides, it’s advisable to use as many images as needed. Images are not just for aesthetics but are crucial in fulfilling the article’s educational purpose.

3. Checklists

Checklists typically feature far fewer images compared to lists or how-to guides.

To be precise, there’s one image for every 898 words.

However, focusing solely on this ratio for checklists can be misleading.

A review of top-performing checklists on Google reveals they’re generally shorter with usually just a single image at the beginning.

This indicates that people prefer checklists that are concise and straightforward.

Key Takeaway: A single image at the start of your checklist article is usually sufficient. In checklists, it’s the actual checklist that adds value, not the images.

4. Case Studies

On average, case studies feature one image every 307 words.

This ratio isn’t extremely image-heavy, but case studies do include a notable number of images.

And rightly so.

In case studies, you often need to support your findings with screenshots, charts, graphs, and similar visuals.

Key Takeaway: Including a significant number of relevant images in case studies is advisable. These images add substantial value to the reader’s understanding.

5. Long-Form Informational Posts

For this analysis, the benchmark for long-form informational posts was a minimum of 3,000 words, with some extending over 7,000 words.

These posts are comprehensive, delving deeply into their subjects and offering extensive information.

On average, they tend to have one image for every 240 words.

In long-form content, numerous images are essential to break up lengthy text segments.

Key Takeaway: Incorporating an image every 200-250 words in long-form informational posts is effective in making the content more approachable and engaging for readers.

6. Statistics Posts

Statistics posts I’ve researched average one image per 216 words.

Statistics posts are engaging, especially when stats are complemented with visual aids like charts or graphs.

This image-to-text ratio indicates that many creators embrace visuals in their content.

Yet, it’s important to remember that readers primarily seek statistical information, not imagery.

Images serve to enhance the content’s appeal and facilitate easier consumption.

Notably, numerous statistics pages thrive without any images, proving they are not essential.

Key Takeaways: View images as supporting elements in statistics posts, akin to backing vocals to the main act of numbers and data. They should enhance, not overshadow, the content. Feel free to use images, including charts and graphs, as they all count as visual elements.

7. Reviews

I categorize reviews into:

  • Single product reviews
  • Round-up reviews

This distinction matters because posts like “Best X for Y,” which feature multiple products, typically have a consistent image-to-product ratio.

In 90% of cases, each product in the review is accompanied by one image.

It’s an effective, straightforward approach.

Single product reviews, however, differ significantly due to their nature.

Let’s explore both types.

Single Product Reviews

Single product reviews are less formulaic than round-up reviews, making the image/text ratio crucial.

Typically, single product reviews feature one image per 262 words.

Key Takeaway: Images in single product reviews are critical, often highlighting product features that are challenging to describe textually. An important aspect is that using your own photos adds significant credibility, demonstrating the reviewer’s personal experience with the product.

Round-up Product Reviews

Round-up product reviews follow a straightforward formula.

They consist of a list of similar products, where the reviewer compares them and picks the overall winner, best budget option, and best for specific uses.

In these reviews, the use of images is as straightforward as the article’s structure, typically one image per product.

Research shows round-up reviews have one image per 237 words.

Key Takeaways: Employing one image per product in round-up reviews aligns with common internet practices. Here, images serve as supportive content, adding substance by visually representing the reviewed products.
