What Is a Sitemap?
A sitemap is a file that lists all pages on your website to help search engines like Google find and index your content. And possibly make it easier for users to navigate your site.
Sitemaps have two main formats:
Here's how they look:
Some companies also create visual sitemaps when planning their website architecture. Like this:
This helps designers plan page hierarchy and understand how content will connect before building the site.
Why Are Sitemaps Important?
Sitemaps help search engines discover and crawl your pages.
Search engines must find each page before indexing (storing) and ranking (showing as a listing) it in search results. Here's how it works at a high level:
When search engines visit your site, they typically follow links from page to page.
Problems arise if:
A sitemap solves these issues by providing a clear directory of the pages you want crawled and indexed.
Different Types of Sitemaps
XML Sitemaps
An XML sitemap is a file created specifically for search engine bots to help them discover pages on your website.
It contains a list of important URLs on your website and may also mention:
Here's a simple example of what XML code looks like in a sitemap:
You'll typically find XML sitemaps at addresses like "yourwebsite.com/sitemap.xml."
HTML Sitemaps
An HTML sitemap is a webpage with links to important areas of your website for users to navigate around more easily. It often lists categories or sections that help visitors understand your site's structure at a glance.
For example, an HTML sitemap might be located at "yourwebsite.com/sitemap" and look like a table of contents:
HTML sitemaps are less common now but can improve user experience on large or complex websites.

XML Sitemap Examples
XML sitemaps list URLs for efficient crawling. Many large brands use them to show all key pages at once.
Here are some examples of sitemaps in XML format:
1. Samsung's XML Sitemap
URL: https://www.samsung.com/sitemap.xml
2. Best Buy's XML Sitemap
URL: https://www.bestbuy.com/sitemap.xml
3. Shopify's XML Sitemap
URL: https://www.shopify.com/sitemap.xml
4. OpenAI's XML Sitemap
URL: https://openai.com/sitemap.xml
HTML Sitemap Examples
HTML sitemaps appear as webpages focused on organizing information that help users browse your site.
Here are some real examples of simple sitemaps:
1. Microsoft's HTML Sitemap
URL: https://www.microsoft.com/en-us/sitemap
2. Airbnb's HTML Sitemap
URL: https://www.airbnb.co.in/sitemaps/v2
3. Walmart's HTML Sitemap
URL: https://www.walmart.com/store-directory
4. Apple's HTML Sitemap
URL: https://www.apple.com/sitemap/
Sitemap Best Practices
Include Page Priority If Desired
In XML sitemaps, use a <priority> tag if you want to show which pages matter most. Values range from 0.0 (lowest) to 1.0 (highest).
Just know that Google ignores this tag.
Indicate Change Frequency If Desired
The <changefreq> tag specifies how often content changes.
There are seven <changefreq> values:
As with the <priority> tag, Google ignores the <changefreq> tag.
Avoid Noindex Pages
Noindex pages tell search engines not to display certain pages in results. Don't include such pages in your sitemap to avoid creating mixed signals.
Only include pages you want visitors to find through search engines.
Avoid Duplicate Content
Duplicate pages should stay out of your sitemap. Search engines allocate resources (sometimes called a "crawl budget "), so focusing on unique pages is best.
This ensures search engines can easily discover and index your most valuable content.
Use Multiple Sitemaps
A single XML sitemap can hold up to 50,000 URLs and can't exceed 50 MB.
If your website is larger, create multiple sitemaps grouped with a sitemap index file to organize them.
Large websites often create separate sitemaps for different content types (blog posts, product pages, etc.) to better organize their site structure for search engines.

An error-free sitemap helps search engines crawl and index your webpages properly.
