What is a sitemap?

A sitemap is usually a file called sitemap.xml that sits quietly on your website. It is not a page your visitors read. Instead, it is written for search engines, giving them a tidy list of every page on your site along with hints about when each page was last updated. Search engines send out automated crawlers to explore the web, and a sitemap makes sure they do not miss anything, especially newer pages or ones that are not linked from your homepage.

It matters because a page that Google never finds is a page that will never show up in search results. Imagine a small photography studio that adds a new portfolio page. Without a sitemap, that page might sit undiscovered for weeks. With one, search engines are pointed straight to it. A sitemap works alongside a robots file, which tells crawlers where they are and are not allowed to go. Together they support your wider meta description and overall discoverability. It is also a quiet part of good responsive design and site health.

You never have to write or upload a sitemap yourself. Promino automatically creates and keeps your sitemap up to date every time you add, edit or publish a page, so search engines always see the current shape of your site.

It also generates a matching robots file and submits the right signals for you, so your pages are ready to be found the moment they go live. You can read more about how we handle discoverability on our SEO page.
