Add the badge to your site

Show visitors that Datum Marketplace is listed here — it’s also the link we check for a free listing.

HTML — for your website

<a href="https://serverdex.io/server/co-datummarket-datum-mcp-server?utm_source=badge"><img src="https://serverdex.io/brand/badge.svg" alt="Datum Marketplace — listed on Serverdex" width="123" height="40" loading="lazy"></a>

Recommended. A dofollow link from your own domain is the one that counts for search engines, and it's the link we check for a free listing.

Markdown — for your README

[![Datum Marketplace — listed on Serverdex](https://serverdex.io/brand/badge.svg)](https://serverdex.io/server/co-datummarket-datum-mcp-server?utm_source=badge)

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
