What is a sitemap?
A sitemap is an XML file that lists all important URLs of your website. It helps search engine crawlers find and index your pages efficiently.
Example: a company launches a new website with service pages, a blog and a contact page. Its file sitemap.xml lists the URL of each of these pages, and the robots.txt file points to it, so crawlers know where to start.
Why does a sitemap matter?
- Crawl efficiency – Google finds new and updated pages faster
- Large websites – with many pages, a sitemap is essential
- New websites – it speeds up the first indexing
- Priorities – it signals to Google which pages are especially important
