Yes. Submission to Cornerstone23 is entirely free of charge. There are no listing fees, annual renewals, or premium tiers. Approved entries remain in the directory indefinitely.

Websites in Cornerstone23 are classified by primary subject matter into one of twenty-two defined divisions, ranging from computing technology and financial services to travel, health, and general reference. Each submission is placed in the division most closely corresponding to the site's main purpose.

Use the submission form on the Add a Site page. Enter your website's URL and select the appropriate subject division. The editorial team will review the submission and, if approved, publish the entry in the directory.

Most submissions are reviewed promptly upon receipt. The directory does not publish a guaranteed turnaround time, as this depends on the volume of submissions received. Approved entries are made live in the directory upon completion of review.

If you need to update your site's title, description, or category, contact the editorial team through the About page. We aim to keep the catalogue accurate and will make reasonable corrections on request.

Cornerstone23 does not accept entries that are under construction, redirect to unrelated content, or contain unlawful material. All other categories of website are considered on their merits during editorial review.
