## Key takeaways

- Give each visual a reader task.
- Review what the image implies as well as what it shows.
- Keep generated scenes separate from real evidence.

Choose blog images by naming the job each visual will do for the reader. It may show a step, explain a comparison, or make a product detail clear. Originality is useful when it adds meaning. A new decorative scene does not by itself improve a guide. Start with the [image SEO guide](https://www.getdexseo.com/blog/image-seo/) for the shared publishing checks.

## Give the visual one clear job

Read the section and name what may be hard to understand from text alone. A photo can show a physical detail. A diagram can show a sequence. A chart can show a checked comparison. Write the intended contribution before searching a library or asking a tool to create a scene.

If you cannot name that job, consider leaving the section as text. More images can add more work for the reader without helping them. Do not treat a fixed image count as a search-engine rule. Let the article’s task and the actual facts decide.

## Choose blog images from a short brief

Write the subject, reader question, required details, and what must not be implied. Add the intended placement and the need for a text alternative. For a service article, include the real scope of the business. A brief should prevent a polished visual from making a false claim.

Choose a format suited to the job. A screenshot may fit a real interface step. A diagram may fit a process. A table may serve an exact lookup better than a chart. When you choose a data visual, plan its [chart description](https://www.getdexseo.com/blog/image-seo/describe-charts-accessible-text/) from the same source values.

## Compare real candidate images

Review two or three candidates against the brief. Ask which one answers the reader’s question most clearly. Note missing details and possible false impressions. A generic team photo may fit the brand colors while doing little to explain the task in the section.

Do not claim that an image is evidence simply because it looks realistic. A stock photo is not a photo of your team. A generated office is not a client project. Use a real source when the article claims to show real work, and label illustrations where that distinction matters.

## Example: choose a visual for a service process

Imagine a fictional article about preparing a repair request. The options are a smiling worker, a diagram of the request steps, and a photo showing the detail the customer should capture. The best choice depends on the question the section answers. This is a planning example, not a measured test.

For the section about what photo to send, the detail view may be most useful. For the section about what happens next, the process diagram may work better. The generic worker photo may be suitable for a cover, but it does not replace those explanations. One visual need not solve every task.

## Check product identity and visible claims

If the article discusses a clear item, compare the image with the actual product and variant. Do not show an accessory as included when it is not. Keep logos, labels, and interface states correct. A wrong image can mislead even when the nearby paragraph is correct.

Use the [product-image review](https://www.getdexseo.com/blog/image-seo/product-images-google-search/) for that task. Do not turn visual selection into a second guide to product markup or page speed. Here, the decision is whether this image adds true, useful facts to the article’s section.

## Use generated images with a review step

DEX can generate images as part of the article workflow. Give that process a clear brief tied to the business’s products and services. Review the result for wrong labels, made-up details, and claims a reader may infer from the scene. Do not approve only because it looks polished.

Generated visuals can help explain a concept. They should not invent a real client, a measured result, or a product feature. Use checked source material when those facts matter. Keep a person named for deciding what is suitable to publish under the business’s name.

## Keep important words and meaning accessible

Avoid putting the main answer only inside the picture. A graphic with key wording needs a readable equivalent. Use the [text-in-image review](https://www.getdexseo.com/blog/image-seo/images-of-text-accessibility/) when dates, instructions, or limits appear in the artwork. The article should not depend on a reader deciphering small lettering.

Plan a text alternative suited to the visual’s role. A simple concept may need a short description. A detailed comparison may need more. Do not force every illustration into the same generic alt phrase. The purpose on the page helps decide what the reader needs.

## Review placement in the actual section

Place the visual where it supports the useful explanation. Add a caption only when it gives useful context. Check the image with the paragraphs before and after it. A visual placed far from its explanation can be harder to interpret, even when both are correct.

Review the public version on a small screen. Can the reader see the needed detail? A wide screenshot may become unreadable when reduced. The answer may be to crop to the useful step, split the content, or use more real text. Keep file-speed work in the separate performance process.

## Audit the result rather than just the file

Use an [image alt-text audit](https://www.getdexseo.com/blog/image-seo/image-alt-text-audit/) to review how the chosen asset is used across published pages. The same file may support different tasks. A library description may fit one use and fail another. Review the page context before applying one change everywhere.

Keep the original source and the reason for choosing the visual. If it came from a client or supplier, keep the right approval and rights record. Do not copy a competitor’s visual simply because it makes the topic look familiar. Create or obtain a suitable asset for the actual task.

## Use a quick image-choice test

Show the section and two image options to a second person. Ask which picture helps them answer the section’s main question. Do not tell them which option you prefer. If neither helps, keep that result. The brief may need a clearer job, or the section may work best as text.

Ask what the chosen picture seems to claim. A reader may see a real project where the team intended a concept. Fix that gap with a better asset or clear context. The test is small and does not prove a conversion lift. It helps catch a false or useless message before launch.

## Close the brief with a clear decision

Record the chosen visual, its job, source, and review owner. Check that the key details are true and its alternative is planned. If none of the candidates helps, revise the brief or use text. A blank image slot is not a reason to publish a weak visual.

Revisit the choice when the article or service changes. A screenshot or process view can become outdated before the prose does. Keep the visual connected to the same reader task. That makes original imagery a useful part of the article rather than a decorative layer added at the end.
