Accessibility (WCAG) and SEO - how to make your site work for every user?

📖 Detailed description

Digital accessibility (Web Accessibility) is not only a legal and ethical requirement, but also a meaningful ranking factor. Google promotes sites that are friendly to all users, including people with disabilities (in line with the WCAG standards).

Elements such as alternative text (alt) for images, adequate contrast, and a semantic heading structure all help Google's crawlers better "understand" and index the content of your site.

An accessible site also means a better User Experience (UX), which translates into a lower bounce rate and more time spent on the page.

Most common problems

No lang attribute

Screen readers do not know which language to read in

No alternative text

Blind users cannot tell what is in the images

Poor contrast

Text is unreadable for people with low vision

No form labels

It is unclear what to enter in each field

How to fix it?

Declare the page language in the lang attribute

Add alt descriptions to all images

Ensure strong contrast between text and background

Use semantic HTML (nav, main, footer)

Make sure forms have labels

Examples

Good example

<html lang="en">, <img src="..." alt="Image description">

Bad example

<html>, <img src="..."> with no alt
