Anchors Using `javascript:void(0)` or `javascript:;`

Anchors using `javascript:void(0)` or `javascript:;` suppress navigation but cause accessibility and SEO issues.

By Seoxpert Editorial · Published May 1, 2026

Why it matters

Using `javascript:void(0)` in anchor tags is an outdated workaround that creates accessibility, usability, and security problems. It can break keyboard navigation, confuse screen readers, and violate Content-Security-Policy rules, negatively affecting both user experience and SEO.

Impact

Leaving this unresolved can harm accessibility, break functionality for some users, and reduce SEO effectiveness.

How it's detected

Automated crawlers scan for anchor (`<a>`) tags with `href` attributes set to `javascript:void(0)` or `javascript:;`.

Common causes

•Using anchors for button-like actions instead of real buttons
•Copy-pasting legacy code patterns
•Lack of awareness of modern button styling
•Attempting to prevent default anchor navigation without considering accessibility

How to fix it

Replace `<a href="javascript:void(0)" onclick="...">` with `<button type="button" onclick="...">`. Style the button to look like a link using CSS if needed. This approach is semantically correct, accessible, and compatible with Content-Security-Policy.

Code examples

Problem: Anchor using javascript:void(0)

<a href="javascript:void(0)" onclick="doSomething()">Click me</a>

Solution: Button styled as link

<button type="button" onclick="doSomething()" class="link-button">Click me</button>

<style>
.link-button {
  background: none;
  border: none;
  color: #06c;
  text-decoration: underline;
  cursor: pointer;
}
</style>
