Midjourney is an AI image generator that turns text prompts into detailed pictures, used through its website and Discord. For SEO, it changes how quickly you can produce original visuals, but it does not change how search engines evaluate images. File names, alt text, page context, speed and genuine usefulness still decide whether an image helps a page rank or appear in image results.
Can AI-generated images rank in Google Images?
Yes. Google does not ban images because they were made with AI. Google’s guidance asks for clear labeling in some contexts, such as merchant listings where AI images must carry metadata, and it adds IPTC metadata to its own generated images. For ordinary editorial use, ranking depends on the same factors as any other image.
Midjourney images are original files, which is an advantage over stock photos that appear on hundreds of sites. An image that exists only on your page gives Google a unique asset to connect with your content. The catch is relevance: a beautiful but generic picture of a glowing brain on an article about email marketing adds little.
Where Midjourney helps SEO
- Custom header images for blog posts instead of overused stock photos
- Concept illustrations that explain abstract ideas, such as a funnel or a data flow
- Lifestyle scenes for products before a photoshoot is possible
- Consistent visual style across a content series using style references
- Social preview images that make shared links more clickable
Click-through rate is an underrated factor. Images in Discover, image search and social previews influence whether someone clicks. A distinctive visual that fits the headline can lift clicks, while the same stock image your competitor used last week will not stand out.
Where it can hurt
The risks are practical. Midjourney exports large files, often heavy PNGs. Dropped straight into a page, they slow down loading and can hurt Largest Contentful Paint, which Google measures as part of Core Web Vitals with a good threshold of 2.5 seconds. A slow page loses more than a pretty image gains.
Trust is the second risk. AI images of people, places or products that do not exist can mislead readers. A fake photo of your team or a product image that shows features it lacks damages credibility and may break advertising and consumer rules. Use AI for illustration, not for evidence.
- Heavy files that slow pages and hurt Core Web Vitals
- Visual errors such as distorted hands or garbled text that look careless
- Misleading product or people images
- Generic visuals that do not match the topic
- Rights uncertainty, since AI images may not be protected by copyright
How do you optimize Midjourney images for search?
Treat each generated image like a photo you commissioned. Rename it, compress it, describe it and place it where it supports the text. The steps are not new, but they are often skipped when images are cheap to make.
A checklist for each image
- Upscale only as much as needed, then resize to the display width
- Convert to WebP or AVIF and compress to a sensible size for the layout
- Use a descriptive file name, such as linen-sofa-cat-friendly.webp, not a Midjourney job ID
- Write alt text that describes the image for someone who cannot see it
- Place the image near the text it illustrates and add a caption if it explains something
- Set width and height attributes to prevent layout shift
- Lazy load images below the first screen, but not the main hero image
Should you label AI images?
For merchant listings, Google requires AI-generated product images to keep metadata such as IPTC DigitalSourceType. For editorial content there is no general ranking rule, but labeling is good practice when an image could be mistaken for a real photo. A short caption such as ‘illustration created with Midjourney’ is honest and costs nothing.
Be careful with image compression tools that strip metadata. If labeling matters for a page, check that the final file still carries it, or rely on a visible caption instead.
How Alien Road applies Midjourney
In a typical engagement our design team builds a visual style guide for the client’s content first: color palette, composition rules, subjects to avoid and a set of approved style references. Prompts are saved in a shared library so the look stays consistent across writers and months.
Each image goes through a production step that handles upscaling, cropping for the layout, WebP export, file naming and alt text. A designer checks for visual errors and brand fit. We then track image search impressions in Search Console with the search type set to Image, along with page speed for the templates that use them, so the client can see whether the new visuals add traffic without slowing the site.
Midjourney versus stock and photography
Stock photos are fast and legally clear but common. Real photography is the most trusted and best for products, people and locations, but it takes time and budget. Midjourney sits between them: quick and unique, best for concepts and illustrations. Most content programs end up using all three, with a rule for which one fits which page type.
How do you write good alt text for AI images?
Alt text should describe what the image shows and why it is on the page, in a sentence. For a Midjourney illustration of a sales funnel made of glass layers, ‘Illustration of a four-stage sales funnel with leads narrowing toward a single purchase’ works. ‘AI image’ or a string of keywords does not help users or search engines.
Do not paste your prompt into the alt attribute. Prompts are written for the model, full of style terms like ‘cinematic lighting, 8k’, and they describe nothing useful for a screen reader. Keep a separate field in your asset library for the prompt and another for alt text.
- Describe the subject and the action
- Mention text in the image only if it matters
- Keep it under roughly 125 characters where possible
- Leave alt empty for purely decorative images
Where to start this week
Pick three blog posts that use generic stock images and get steady traffic. Create one Midjourney illustration for each that shows the actual idea of the post. Export as WebP, name the file clearly, write alt text and replace the old image. Note the date, then check image impressions and page speed in a month.
