Check if the redirect between www and non-www versions of your site is configured to prevent duplicates
This only checks www redirect. For a comprehensive analysis, use the full page check.
You can also audit your entire site. Duplicate titles and descriptions, orphan pages, broken links between sections, and other site-wide issues can only be found with a full site audit.

A domain with www (www.example.com) and without www (example.com) are technically two different hosts. If both are accessible without a redirect, search engines index them as two separate sites with identical content. This leads to page duplication, link equity dilution, and lower search rankings. Setting up a 301 redirect from one version to the other solves this problem.
From an SEO perspective, there's no difference between www.example.com and example.com. What matters is choosing one and setting up the redirect. Consider the following:
When the site is accessible at both addresses, search engines treat them as separate pages. External links split between www and non-www versions, reducing each one's authority. A canonical tag helps indicate the preferred version, but a 301 redirect is a more reliable solution as it physically redirects all requests and passes 100% of link equity.
