Image SEO for WordPress
Alt text is a short description of an image that helps people using screen readers and helps search engines understand your images. But it is easy to forget while writing. CrawlWP fills in missing alt text from the image title or file name, and never touches alt text you wrote yourself.
What it does
What CrawlWP image SEO does
Turn it on once, and it fills in alt text for images without it.
On this page
Auto-fill missing alt text
Images with no alt text get it filled in automatically.
Uses the image title first
If the image has a title in the media library, that becomes the alt text.
Falls back to the file name
No title? CrawlWP uses the file name instead.
Your own alt text wins
Alt text you wrote by hand is never replaced.
One switch
Tick one box. There is no per-image work to do.
Covers the images in your posts
Images in your content that have no alt text get it filled in.
Better for screen readers
People who cannot see an image hear a description instead of nothing.
Better for image search
Alt text is one of the signals Google uses to understand what an image shows.
Flagged in content analysis
The SEO metabox flags images without alt text so that you can write better ones.
Nothing to maintain
Once it is on, it keeps working as you add new posts.
No coding needed
No theme edits and no extra WordPress plugin.
Free
Image SEO is part of CrawlWP Lite, the free version.
Why it matters
Why alt text matters
Screen readers read alt text aloud for people who cannot see the image. Search engines use it, together with the text around the image, to understand what the image shows.
Many images end up with no alt text because it is easy to forget. Auto-fill gives every image something useful, and you can still write better alt text for the images that matter most.
How it works
Fix missing alt text in three steps
It takes a minute, and it keeps working after that.
Step 1
Switch it on
On the Image SEO screen, tick Auto-fill missing alt text and save.
Step 2
Name your images well
Give images a clear title or file name, such as red-running-shoes.jpg. That is what the alt text is built from.
Step 3
Write your own where it matters
For your key images, write alt text by hand. CrawlWP never replaces it.
Writing good alt text
How to write good alt text
Auto-fill is a good start. For the images that matter most, these tips help you do better.
Questions
Image SEO questions
Answers to the questions people ask most about image SEO and alt text in WordPress.
What is alt text?
It is a short text description of an image, added in the image’s alt attribute. Screen readers read it aloud, and search engines use it to understand the image.
Why does alt text matter for SEO?
Google uses alt text, along with the surrounding page content, to understand what an image shows. It helps your images appear in Google Images.
Is auto-filled alt text as good as writing it?
No, and it is not meant to be. It is much better than nothing, and it covers images you will never go back to. Write your own for the images that matter most.
Will it overwrite alt text I already wrote?
No. Alt text you wrote by hand is left exactly as it is.
Where does the text come from?
The image title in the media library. If there is no title, the file name is used.
My file names look like IMG_1234.jpg. Will that work?
The alt text will be just as unhelpful. Give the image a clear title in the media library, and CrawlWP will use that instead.
Is Image SEO free?
Yes. It is part of CrawlWP Lite, the free version.
