Create perfect H1 heading for SEO and Accessibility

Headings communicate the organization of the page’s content. The h1 heading, which is usually the largest heading on a page, describes the main topic of the page and typically corresponds to the title of the page. It gives users an indication of what the page is about.

The h1 heading influences visitors’ decisions about whether or not to continue reading a page. It communicates the page’s relevance to search engines.

According to the WCAG headings rules, levels should be used hierarchically, with the main heading being the highest level (h1) and subheadings being subsequent lower levels (h2, h3, h4, etc.). This structure makes it easier for people with visual impairments, cognitive disabilities, and learning difficulties to easily understand the content of a web page.

In this article, we’ll go over all you need to know about the h1 heading and how to make the most of it from the perspective of the user, SEO, and accessibility!

Accessibility and Performance

Performance and accessibility are two important aspects of web development. Since they are related, optimising one might result in improvements in the other.

Web performance is all about making websites fast: loading, rendering, and interacting.

When pages load slowly or have a lot of content to load, the experience can be very clunky and unpleasant for all users. More resources to download also mean more data that needs to be transferred through the network and processed. Let’s explore the user and business impact and how this could be improved.

Accessibility focuses primarily on making websites usable for people with disabilities. However, many accessibility requirements also improve usability for everyone. For example, good color contrast means all users can see your content no matter what device they’re using or the lighting in their surroundings.

3 simple tips to make text over image more readable

If you add text over a background image, make sure there is enough contrast to make it readable. Subtle changes may be made to boost contrast without changing the overall aesthetic of the site.

The Web Content Accessibility Guidelines (WCAG) is an internationally recognized standard created by the World Wide Web Consortium (W3C), and WCAG calculates it as a ratio describing the relative luminance of the text and background.

Let’s then see 3 tips to make text over image more readable.
