What is an XML Sitemap and Why is it Important?

An XML sitemap is a file that lists all the important URLs on your website. It acts as a roadmap for search engines, guiding them to all your key content and helping them understand your site's structure.

While search engines can find pages by crawling links, a sitemap ensures they don't miss anything, especially:

• New pages: Helps search engines discover new content faster.
• Deeply nested pages: Pages that are many clicks away from the homepage.
• Orphan pages: Pages that have no internal links pointing to them.
• Sites with a lot of content: Keeps crawlers organized and focused on what matters.

Beyond just listing URLs, an XML sitemap can also provide valuable metadata about each page, including:

• When the page was last updated.
• How often the page changes.
• The priority of the page relative to others on your site.

By providing this information, you help search engines crawl your site more intelligently, ensuring your most important and freshly updated content gets indexed quickly.

How to Create and Submit an XML Sitemap

Creating a sitemap is easier than it sounds. Here’s a step-by-step process:

Step 1: Create the Sitemap File

You have a few options for generating a sitemap:

• Using a CMS Plugin: If you use a platform like WordPress, plugins like Yoast SEO or Rank Math will automatically generate and update an XML sitemap for you. This is the easiest method.
• Online Sitemap Generators: Websites like XML-Sitemaps.com can crawl your site and create a sitemap file for you to download. This is a good option for smaller, static websites.
• Manual Creation: For very small sites, you can write the XML code yourself, but this is prone to errors and not recommended for most users.

A basic sitemap entry looks like this:

<url>
  <loc>https://www.yourwebsite.com/your-page</loc>
  <lastmod>2024-10-26</lastmod>
  <changefreq>monthly</changefreq>
  <priority>0.8</priority>
</url>
 

• <loc>: The URL of the page. This is the only required tag.
• <lastmod>: When the file was last modified.
• <changefreq>: How often the page is likely to change.
• <priority>: The importance of this URL relative to others on your site (from 0.0 to 1.0).

Note: Google has stated that it largely ignores <changefreq> and <priority>, focusing primarily on <loc> and <lastmod>.

Step 2: Submit Your Sitemap to Search Engines

Once your sitemap is created and uploaded to your website's root directory (e.g., yourwebsite.com/sitemap.xml), you need to tell search engines about it.

1. Via Robots.txt: As shown earlier, add Sitemap: [your_sitemap_url] to your robots.txt file.
2. Via Google Search Console: This is the recommended method.
3.  
   • Log in to your Google Search Console account.
   • Go to "Sitemaps" in the left-hand menu.
   • Enter the URL of your sitemap and click "Submit."
   • Search Console will then process your sitemap and report any errors.

A basic sitemap entry looks like this:

<url>
  <loc>https://www.yourwebsite.com/your-page</loc>
  <lastmod>2024-10-26</lastmod>
  <changefreq>monthly</changefreq>
  <priority>0.8</priority>
</url>

• <loc>: The URL of the page. This is the only required tag.
• <lastmod>: When the file was last modified.
• <changefreq>: How often the page is likely to change.
• <priority>: The importance of this URL relative to others on your site (from 0.0 to 1.0).

Note: Google has stated that it largely ignores <changefreq> and <priority>, focusing primarily on <loc> and <lastmod>.

What is a Robots.txt File and Why is it Important?

A robots.txt file is a simple text file that gives instructions to web crawlers (or "robots") about which pages or sections of your website they should not access. It's the first file search engine bots look for when they visit your site.

Why would you want to block crawlers from certain pages?

• To prevent crawling of low-value pages: This includes things like internal search results, admin login pages, or duplicate content.
• To manage crawl budget: Every site has a "crawl budget," which is the number of pages a search engine will crawl in a given period. By blocking unimportant pages, you ensure this budget is spent on your valuable content.
• To keep private sections private: Block access to staging areas or sections of your site that aren't meant for public viewing.

Important Note: Using robots.txt to block a page does not guarantee it won't be indexed. If another site links to your blocked page, Google might still index it without crawling the content. To prevent a page from appearing in search results, you should use a noindex meta tag or an X-Robots-Tag HTTP header.

How to Create and Use a Robots.txt File

A robots.txt file lives in the root directory of your website (e.g., yourwebsite.com/robots.txt).

Common Robots.txt Directives

• User-agent: Specifies which crawler the rule applies to. User-agent: * applies to all crawlers. User-agent: Googlebot applies only to Google's main crawler.
• Disallow: Instructs the crawler not to access a specific file or directory. Disallow: /wp-admin/ blocks access to the WordPress admin folder.
• Allow: Explicitly permits crawling of a subdirectory or file within a disallowed directory. This directive overrides Disallow.
• Sitemap: Specifies the location of your XML sitemap(s).

Example Robots.txt File:

# Block all crawlers from the admin and checkout folders
User-agent: *
Disallow: /admin/
Disallow: /checkout/

# Allow Google's image bot to see all images
User-agent: Googlebot-Image
Allow: /

# Point all crawlers to the sitemap
Sitemap: https://www.yourwebsite.com/sitemap.xml
 

Testing and Validating Your Files

Errors in these files can cause significant SEO problems. Always test them.

• Robots.txt Testing: Use Google Search Console's robots.txt Tester. It will show you if a specific URL is blocked for Google's crawlers and highlight any syntax errors.

• XML Sitemap Validation: When you submit your sitemap in Google Search Console, it will automatically be validated. The "Sitemaps" report will show its status and let you know if any URLs have issues.

   

  How XML Sitemaps and Robots.txt Work Together for SEO

• Think of it this way:

• Robots.txt tells crawlers where they can't go.
• An XML sitemap tells crawlers where they should go.

• These two files work in tandem to create an efficient crawling strategy. First, a crawler checks the robots.txt file for its "do not enter" signs. Then, it uses the XML sitemap to get a curated list of all the important destinations.

• For best results, you should include a line in your robots.txt file that points directly to your sitemap's location. This makes it even easier for search engines to find and use it.

• User-agent: *
  Disallow: /admin/
  Disallow: /private/
  
  Sitemap: https://www.yourwebsite.com/sitemap.xml
   

Advanced Techniques and Best Practices

• Large Websites: If your site has more than 50,000 URLs, or the sitemap file is larger than 50MB, you need to split it into multiple smaller sitemaps. Then, create a sitemap index file—a sitemap that links to your other sitemaps—and submit the index file to Google.
• Multilingual Websites: For multilingual sites, use hreflang annotations to tell Google about the different language versions of a page. You can include hreflang information directly within your XML sitemap. This is often more efficient than adding it to the <head> of every page.
• Video and Image Sitemaps: If images and videos are critical to your business, consider creating separate image and video sitemaps to help search engines discover and index your rich media content more effectively.
