How to Use Image Alt Text Optimization Tools Effectively

Image alt text optimisation tools are very helpful for making your website’s images more accessible and better for SEO. Here’s how to make good use of them:

Choose the Right Tool: Yoast SEO, Image SEO Tool by SEO Review Tools, and Alt Text Checker by Siteimprove are some of the image alt text optimisation tools that you can use. Pick a tool that works well with your current workflow and meets your needs.

Upload or Type in Images: Depending on the tool, you can either type in image URLs or upload images directly. Make sure you pick the pictures you want to improve.

Look at the suggested alt text: After the images or URLs are uploaded, the tool will offer alt text suggestions based on image recognition technology or what you type in by hand. Carefully read over these suggestions.

Change the Alt Text: The tool’s suggestions can be useful, but you need to change the alt text to accurately describe what the image is about. Think about where the image fits on the page and include relevant keywords when it makes sense.

Focus on Descriptiveness: Pay attention to how descriptive the alt text is. It should clearly explain what the image is about and how it can be used to people who can’t see it. Try not to be too wordy while still giving enough information for someone to understand what the picture means.

How to choose the Right Tool for Your Alt Text Optimization Needs

When picking the right tool for alt text optimisation, there are a few things you should think about that can affect how well and quickly your image optimisation works. How to Pick the Right Tool:

Figure out what you need: Know why you need the tool. Are you mostly looking for a tool that will automatically make alt text for images, or do you also need one that will let you change the alt text for each image by hand? Do you need extra features like analysing images, making sure the site is accessible, or connecting to other platforms?

Look into the Tools That Are Out There: Look into the tools that are out there that are designed specifically for optimising alt text. Look for tools that can do things like automatically create alt text, edit alt text by hand, process a lot of files at once, analyse images, check for accessibility, and integrate with other programmes.

Think about how easy it is to use: Pick a tool that is simple to understand and get around. The tool’s interface should be easy to use, so you can quickly learn how to make the alt text for your images work best. Check to see if the tool makes it easy to optimise alt text both automatically and by hand.

Check for Accuracy and Quality: Check to see how accurate and well-written the tool’s alt text is. For tools that automatically create alt text, look for ones that use complex algorithms and machine learning to correctly describe images. If you want to edit the alt text by hand, make sure the tool gives you tips and suggestions on how to write descriptive and useful alt text.

Check Customization Options: If you need to edit the alt text by hand, make sure the tool lets you change the alt text for each image so it fits the image’s purpose and context. Look for features that let you add descriptive keywords, relevant content, and follow guidelines for accessibility.


Which AI can write alt text for images?

Image alt text is generated automatically by AltText AI. Include alternative text on every image to boost SEO and site accessibility.

Is alt text legal?

YES! Alt-tags are required by UK and US accessible design laws for all images. Images that serve no purpose (spacers, etc.) can have no alt-tag.
