When the AI Alt Text Generator seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Alt text is too generic
Provide the page context as input - descriptions should reflect why the image appears there.
It reads like keyword spam
Alt text describes the image for visually impaired users first - keep phrases natural.
Decorative images
Leave purely decorative images with empty alt attributes - not every image needs text.
Charts and diagrams get one-liners
Supply the data summary as input - complex visuals need their meaning conveyed, not just their look.
Descriptions are too long
Aim for a clear sentence - longer detail belongs in the caption or surrounding copy.
Did my image search traffic change?
Image search signals improve gradually - monitor alongside other optimisation work.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Stuffing keywords into alt text
- Writing image.jpg as description
- Describing decoration that carries no meaning
- Leaving complex charts unexplained
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
How long should alt text be?
One clear sentence describing the image and its purpose - usually under a dozen words.
Should alt text include keywords?
Only where they describe the image honestly - accessibility comes first, always.
What about decorative images?
Use an empty alt attribute so screen readers skip them entirely.
Is my input stored?
No - generation happens in your browser.
