How to Use Images and Diagrams to Boost AdSense Revenue and Optimize Image SEO｜けん｜アドセンスに裏技なし！正攻法で稼ぐ

When it comes to increasing traffic and extending page dwell time on Google AdSense, the use of images and diagrams plays a role just as important as the text itself.

Long articles filled only with text can give readers the impression that they are “hard to read” or “too difficult” when viewed on a smartphone screen, which is a major cause of immediate page abandonment (early exit).

By placing images and diagrams at appropriate points, you can significantly improve the visibility and readability of your articles, and gain three key benefits: extended dwell time, improved bounce rates, and new traffic from image searches.

In this article, we will explain the “image placement and creation know-how” and “image SEO optimization” that will simultaneously increase reader satisfaction and SEO effectiveness for AdSense sites.

Why does adding images and diagrams lead to AdSense revenue?

Effectively inserting images brings the following direct positive impacts to your site’s traffic and revenue.

1. They provide a “visual break” while scrolling, extending dwell time

When readers scroll through a smartphone screen to read text, their concentration wanes if there is only text. By placing visual images or supplementary diagrams directly under headings (H2), the reader’s eyes stop for a moment, making it easier for them to continue reading to the end of the article.

2. They increase traffic routes (new access) from “image searches”

Properly optimized images will appear higher in Google’s “image search” results. In particular, original diagrams for how-to or comparison content are easy to acquire traffic from image searches, serving as a source of access separate from regular web searches.

3. Ad viewability improves

By ensuring articles are read thoroughly to the end, the opportunities for AdSense ads placed within the body or at the end of the article to be correctly exposed on the user’s screen increase, leading to an increase in revenue per mille (RPM).

Rules for placing and creating “images and diagrams” that produce results

Simply scattering free stock images blindly can sometimes have the opposite effect. Let’s master the tips for effective operation.

① Place “images that supplement the content” directly under headings (H2)

The basic placement point is “directly under the H2 (main heading).” By placing an image that conveys the image of the theme to be explained at a glance, you can help readers predict the flow of the article and guide them smoothly into the main text.

② Turn complex procedures and data into “simple diagrams and tables”

• Procedure explanations: Add arrows or red frames to screen captures (snapshots) of the operation screen.

• Pros and cons comparisons: Present them as a two-column comparison table or comparison diagram instead of text.

By utilizing free design tools like Canva, you can create clean, original diagrams in just a few minutes, even without professional design skills.

3. Keep ‘mobile readability’ in mind for featured images

For featured images that appear in social media shares or related article lists, aim for contrast and font sizes that allow titles and main elements to be clearly identified even on small smartphone screens.

The 3 major ‘Image SEO’ settings evaluated by search engines

When adding images, be sure to perform the following technical settings (Image SEO) so that search engines can correctly understand the content of the images.

1. Properly fill in the alt attribute (alternative text)

The alt attribute is text used when an image cannot be displayed due to a communication error or by screen readers for the visually impaired.

By describing what the image represents concisely and specifically, your ranking in image searches will improve.

2. Use alphanumeric characters related to the displayed content for file names

Instead of uploading with the default name taken by a camera (e.g., IMG_1234.JPG), change it to alphanumeric characters that represent the image content (e.g., adsense-setting-step1.webp) before uploading.

3. Image weight reduction and size adjustment (consideration for display speed)

Images that are too high-quality will degrade page loading speed (Core Web Vitals).

• Convert to and use lightweight formats such as WebP

• Resize the image width to an appropriate resolution that matches the blog’s display area (e.g., around 800px to 1200px)

Visual readability creates ‘high-asset-value articles’

The approach to improving article quality is not just about ‘writing text.’ Keep the perspective of ‘how quickly and clearly can I solve the reader’s questions,’ and incorporate images and diagrams effectively.

The accumulation of efforts to create an easy-to-read structure will, as a result, increase the evaluation of the entire site and lead to stable AdSense revenue.
