An XML sitemap is a file that lists all the important URLs of your site, helping Google discover and index them faster and more completely.
An XML sitemap (yourdomain.com/sitemap.xml) is a file in XML format that lists the site's URLs along with extra data: the last modification date (lastmod), the update frequency (changefreq) and the relative priority (priority). Google uses it as a guide to discover new pages and re-crawl modified ones. It does not guarantee indexing, but it significantly speeds up the discovery of new content — critical for sites with hundreds or thousands of pages.
Without a sitemap, Google can take weeks or months to discover new pages through organic crawling. With a sitemap submitted in Google Search Console, new pages can be indexed within 24-72 hours.

Crawlability is the ability of Google's robots to access, navigate and read your site's pages — an essential prerequisite for indexing and ranking.
Robots.txt is a text file placed at the root of a site that tells crawlers (Google, Bing, GPTBot) which pages they may or may not access and index.
The canonical tag (rel="canonical") tells Google which is the main version of a page when similar or duplicate URLs exist, preventing duplicate-content penalties.
