# Sitemap and robots.txt: what do they do and why are they different?

Sitemaps and robots.txt help crawlers in different ways. One supports discovery; the other controls access to selected paths.

Sitemap robots.txt Crawl

Summary

## What matters before moving forward.

- Sitemaps list relevant URLs for discovery.
- robots.txt controls crawling paths, not guaranteed indexation.
- Mistakes can hide pages or waste crawl resources.

## A sitemap is a map of important URLs

An XML sitemap helps search engines find relevant pages, especially on new sites, catalogues, or large structures.

It should list final indexable pages, not redirects, errors, or duplicate URLs.

## robots.txt defines crawling limits

robots.txt allows or blocks crawler access to paths. It is not the correct tool to remove an already indexed page.

An overly broad rule can accidentally block important resources or sections.

No. It supports discovery, but every page still needs quality, coherent signals, and valid technical access.
