Imagine a visitor who cannot see your images well, cannot use a mouse, or reads your site through a screen reader. If your site was not built with them in mind, that visitor may leave within seconds - not because your product is bad, but because they could not use the page. A free accessibility checker finds these barriers before your visitors do.
An accessibility checker scans a page for common problems: faint text, images with no description, buttons unreachable by keyboard, and forms with no labels. You get a simple list of issues, fix the important ones first, and re-check until the page passes. You do not need to be a developer to improve things.
This guide shows you how to run a free accessibility check in minutes, understand the results with no technical background, and fix the most common problems. Whether you run a business site, a blog, or a store, these steps help more people use your site and stay longer.

A good checker looks at the page the way different visitors experience it, and checks whether it can be read, navigated, and used:
Each issue gets a severity level: error, warning, or notice. Errors block people from using the page. Start with the errors, then work down.
Light grey text on white looks elegant, but is hard to read for many people, especially on a phone in sunlight. Use darker text or background until the contrast is strong. Small text needs more contrast than large headings.
With no description, a screen reader skips an image or reads a meaningless file name. Add a short description of what it shows and why it matters, for example Owner packing handmade soap orders instead of IMG_2041. Decorative images can be marked as decorative so readers ignore them.
Some menus only open on mouse hover, and some pop-ups cannot be closed with a keyboard. Test your site with Tab to move forward and Shift plus Tab to move back. If you get stuck, or cannot see where the focus is, that is a problem to fix. A visible focus outline around the active link helps keyboard users know where they are.
Links saying click here or read more tell a screen reader user nothing out of context. Write links that describe the destination, such as Download the price list. This also helps other visitors scan faster.
A field showing only placeholder text loses its instruction once someone starts typing. Give every field a visible label, like Your name. Mark required fields clearly, and explain errors in words, not just red colour, since some visitors cannot tell red from green.
If a visitor cannot read it, click it, or hear it, they cannot buy from you either. Accessibility is good service, extended to everyone.
An accessibility checker is a free online tool that scans a page and lists barriers stopping people with disabilities from using it, such as low-contrast text, missing image descriptions, and keyboard problems.
For most small websites, yes, as a starting point. A free checker catches the most common and damaging problems, which are also the easiest to fix. Larger sites may later benefit from a manual review.
Check whenever you change your design, add a page, or install a new theme or plugin. A quick check after each change catches new problems early, when they are cheapest to fix.
Accessibility and search engines reward the same things: clear headings, descriptive image text, and mobile-friendly pages. Fixing accessibility issues often improves how search engines understand your pages too.
If you are improving your website, these guides help with the rest: learn why your website is slow and how to fix it, understand what cookie consent banner Indian websites must show, and check whether you need a privacy policy and what to include.
You do not need to fix your whole website at once. Pick your homepage, run the check, and fix the three worst errors. That alone can turn a page that locked people out into one that welcomes them.
Every visitor you keep is a potential customer who might otherwise have left in frustration. Accessibility is not extra work for a small group. It is the same work, done properly, for everyone.
