There are a few best practices to follow when creating alt text:

Keep it Brief
Alt text should be brief, to the point, and easy to read. You don’t want to overwhelm people with too much text.

Use descriptive keywords
When writing alt text, use descriptive keywords that accurately describe the image. This will help people who are visually impaired understand what the image is about.

Avoid describing the appearance of the image
Don’t describe the appearance of the image in your alt text. This is something that people who are visually impaired can’t see. Focus on describing the contents of the image instead.

Use proper grammar and spelling
Make sure your alt text is written in proper grammar and spelling. This will help ensure that it is easy to read and understand.

Check your alt text for accuracy
Before you publish your website, be sure to check your alt text for accuracy. Make sure all the images are properly tagged with alt text, and that the alt text accurately describes the image.

Keep Alt Text 125 Characters or Less
Screen readers and other assistive technologies usually stop reading alt text at the 125 character mark.

It’s best to cap your alt text at this number so it doesn’t get cut off.

Include One Main Keyword for Context
It is a good idea to include a main keyword in your alt text if it provides context for the page the image is on.

Don’t Include “Image of” or “Picture of” in Alt Text
As mentioned, you only have 125 characters to describe your image. Including filler text like “picture of” or “image of” will only waste that space, since it’s already implied to both users and Google that these are images.
