How to Create a Sitemap and Improve Your Site's Indexing

A sitemap is like the treasure map that guides search engines through your site, making sure every valuable page gets discovered, indexed, and shown to the right users.

Imagine building a magnificent house in a remote location, but forgetting to add the address to the GPS. No matter how impressive the construction, few people will ever find it. That’s exactly the challenge many sites face today: great content that stays invisible to search engines.

A sitemap is like the treasure map that guides search engines through your site, making sure every valuable page gets discovered, indexed, and shown to the right users.

In a digital landscape where 90.63% of web content gets no traffic from Google, according to data from Ahrefs, the difference between visibility and obscurity can come down to a simple XML file.

In this complete guide, we’ll unpack the secrets to creating an effective sitemap that not only improves your site’s indexing but also strengthens your overall SEO strategy.

What Is a Sitemap?

A sitemap is a file that lists all the pages on a site you want search engines to know about and index. It works like a digital road map that guides search bots (like Googlebot) through your site’s structure, indicating where each page is located and how they relate to each other.

There are mainly two types of sitemaps:

1. XML Sitemap

This is the most common and important format for SEO. It’s a file structured in XML (eXtensible Markup Language) that search engines can read and interpret automatically. A basic XML sitemap contains:

  • URLs of all relevant pages

  • The date each page was last modified

  • How often the page changes

  • The relative priority of each page within the site

Example of a simple XML sitemap:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://www.yoursite.com/</loc>
    <lastmod>2025-03-15T13:00:00+00:00</lastmod>
    <changefreq>daily</changefreq>
    <priority>1.0</priority>
  </url>
  <url>
    <loc>https://www.yoursite.com/about/</loc>
    <lastmod>2025-02-20T12:30:00+00:00</lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.8</priority>
  </url>
</urlset>

2. HTML Sitemap

This is a sitemap aimed at site users, usually presented as a “Sitemap” page that lists all the important sections and pages in an organized, navigable way. While useful for user experience, HTML sitemaps have much less direct impact on SEO than XML sitemaps.

Why Do Sitemaps Matter?

The importance of a well-structured sitemap goes far beyond simply listing pages. Let’s look at the concrete benefits it provides:

1. Better Discovery and Indexing

According to a study by SEMrush, sites with proper XML sitemaps have indexing rates up to 40% higher. When your site is new, has many pages, or has a complex architecture, sitemaps are particularly crucial to make sure no important page goes unnoticed.

2. Faster Updates in Search Results

When you publish new content or update existing pages, a sitemap with accurate modification dates signals to Google that it should re-crawl those pages. This can cut indexing time from weeks down to days or even hours in some cases.

3. Better Priority Signaling

Through the element in an XML sitemap, you can indicate to search engines which pages are most important on your site. While this doesn’t guarantee better ranking, it helps guide how engines distribute your “crawl budget.”

4. Support for Special Content Types

Modern sitemaps can include information about specific content like videos, images, and news, using dedicated XML extensions. For example, a video sitemap can include duration, category, and thumbnails, increasing the chances of appearing in video search results.

5. Identifying Structural Problems

The process of creating a sitemap often reveals issues on the site, such as orphan pages (with no internal links pointing to them) or inconsistent URL structure, letting you fix them before they affect SEO performance.

What Should Go in Your Sitemap

To maximize your sitemap’s effectiveness, it’s crucial to include the right elements and avoid unnecessary ones. Let’s explore what should be part of your sitemap:

Pages to Include:

  1. Homepage and main section pages – The foundation of your site structure

  2. Product and service pages – Essential for e-commerce sites or businesses

  3. Articles and blog posts – Content that attracts organic traffic

  4. Important category pages – Help engines understand the site’s organization

  5. Contact and about pages – Boost the site’s credibility

  6. Landing pages for permanent campaigns – As long as they remain relevant long-term

  7. Pages with rich media content – Especially if they have important videos or image galleries

John Mueller of Google confirmed in a Webmaster hangout that “pages you consider important to your business should be in the sitemap, even if they have good internal links.”

Important Attributes for Each URL:

  • : The page’s canonical URL (required)

  • : Date of the last modification in W3C format (YYYY-MM-DDThh:mm+TZ)

  • : Approximate frequency of changes (daily, weekly, monthly)

  • : Relative importance between 0.0 and 1.0 (the homepage usually gets 1.0)

What Should NOT Go in Your Sitemap

Including irrelevant or problematic pages can hurt your sitemap’s effectiveness and potentially your SEO. Avoid including:

1. Pages Blocked in robots.txt

If you block a page in your robots.txt file, it shouldn’t appear in the sitemap. That contradiction confuses search engines and can be read as an attempt at manipulation.

2. Pages with “noindex” Tags

Similarly, pages with the “noindex” meta tag signal that you don’t want them indexed, so there’s no point listing them in the sitemap.

3. Duplicate Content

Alternate versions of the same page (like print versions or filter parameter pages) should be left out. Only the canonical version should appear in the sitemap.

4. Low-Quality or Low-Value Pages

Pages with very thin content, temporary thank-you pages, or custom error pages don’t add value to the sitemap.

For security reasons, avoid including:

  • Admin pages or control panels

  • Login or password recovery pages

  • URLs that expose sensitive information or session parameters

  • Internal directories that could reveal server structure

6. Paginated or Filtered Pages

Instead of including every version of pages with filters or pagination (example.com/products?page=1, example.com/products?page=2), prefer including only the main category pages.

7. Files and Resources

Downloadable files like PDFs, individual images, or documents generally don’t need to be in the main sitemap (unless they’re key content on your site).

A Botify study analyzing more than 6 billion pages found that including low-quality URLs in sitemaps reduces average indexing rate by up to 68%. Be selective!

How to Create a Sitemap From Scratch

There are several ways to create a sitemap, from manual methods to automated tools. Let’s go through the main options available:

Method 1: Using CMS Plugins

If you use a popular CMS like WordPress, Joomla, or Shopify, there’s probably a plugin that makes creating and maintaining sitemaps easy.

For WordPress:

  1. Install the Yoast SEO or Rank Math plugin

  2. Go to the plugin settings

  3. Enable the XML sitemap feature

  4. Configure which content to include/exclude

  5. Save your changes

The sitemap is usually available at an address like www.yoursite.com/sitemap_index.xml

For Shopify: Sitemaps are generated automatically and are available at www.yourstore.com/sitemap.xml

Method 2: Using Online Generators

For smaller sites, or when you need more control, there are online generators like:

  1. XML-Sitemaps.com: Lets you generate sitemaps for free for sites with up to 500 pages

  2. Screaming Frog: The free version lets you crawl up to 500 URLs and export as a sitemap

Basic process:

  1. Enter your site’s URL

  2. Configure the crawl settings

  3. Start the generation process

  4. Download the generated XML file

  5. Make manual edits if needed

  6. Upload it to your site’s root directory

Method 3: Manual Creation

For very small sites, or when you need full control, manual creation is an option:

  1. Create a new text file

  2. Add the standard XML header:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  1. For each important page, add a block:
<url>
  <loc>https://www.yoursite.com/example-page/</loc>
  <lastmod>2025-03-15T08:00:00+00:00</lastmod>
  <changefreq>monthly</changefreq>
  <priority>0.8</priority>
</url>

  1. Close the file with

  2. Save it as sitemap.xml

  3. Upload it to your site’s root directory

Method 4: Using APIs and Scripts

For dynamic or very large sites, you may need a programmatic solution:

Python:

import xml.etree.ElementTree as ET
from datetime import datetime
import os

# Create the root element
urlset = ET.Element('urlset')
urlset.set('xmlns', 'http://www.sitemaps.org/schemas/sitemap/0.9')

# List of URLs (in a real application, this would come from a database)
pages = [
    {'url': 'https://www.yoursite.com/', 'priority': '1.0', 'changefreq': 'daily'},
    {'url': 'https://www.yoursite.com/about/', 'priority': '0.8', 'changefreq': 'monthly'},
    # Add more URLs as needed
]

# Current date formatted
today = datetime.now().strftime('%Y-%m-%dT%H:%M:%S+00:00')

# Add each URL to the sitemap
for page in pages:
    url = ET.SubElement(urlset, 'url')
    loc = ET.SubElement(url, 'loc')
    loc.text = page['url']
    
    lastmod = ET.SubElement(url, 'lastmod')
    lastmod.text = today
    
    changefreq = ET.SubElement(url, 'changefreq')
    changefreq.text = page['changefreq']
    
    priority = ET.SubElement(url, 'priority')
    priority.text = page['priority']

# Build the XML tree
tree = ET.ElementTree(urlset)

# Write to file
with open('sitemap.xml', 'wb') as f:
    f.write(b'<?xml version="1.0" encoding="UTF-8"?>\n')
    tree.write(f, encoding='utf-8')

print("Sitemap generated successfully!")

This script can be expanded to pull URLs from a database or crawl your site automatically.

Advanced Sitemaps: Beyond the Basics

For more complex sites or those with specific content types, there are advanced sitemap formats that can significantly improve your visibility:

1. Sitemap Index for Large Sites

If your site has more than 50,000 URLs or exceeds 50MB in file size (Google’s recommended limits), you should split your sitemap into multiple files and create an index:

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://www.yoursite.com/sitemap-products.xml</loc>
    <lastmod>2025-03-15T14:00:00+00:00</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://www.yoursite.com/sitemap-categories.xml</loc>
    <lastmod>2025-03-14T09:30:00+00:00</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://www.yoursite.com/sitemap-blog.xml</loc>
    <lastmod>2025-03-16T11:20:00+00:00</lastmod>
  </sitemap>
</sitemapindex>

2. Image Sitemap

For sites with important visual content, like portfolios, galleries, or e-commerce stores:

<url>
  <loc>https://www.yoursite.com/product/digital-camera/</loc>
  <image:image>
    <image:loc>https://www.yoursite.com/images/digital-camera-front.jpg</image:loc>
    <image:title>Professional Digital Camera - Front View</image:title>
    <image:caption>Model XYZ with 18-55mm lens</image:caption>
  </image:image>
  <image:image>
    <image:loc>https://www.yoursite.com/images/digital-camera-side.jpg</image:loc>
    <image:title>Professional Digital Camera - Side View</image:title>
  </image:image>
</url>

3. Video Sitemap

</url>

4. News Sitemap

For news sites that want to appear in Google News:

<url>
  <loc>https://www.yournewspaper.com/technology/new-seo-update/</loc>
  <news:news>
    <news:publication>
      <news:name>Your Digital Newspaper</news:name>
      <news:language>en</news:language>
    </news:publication>
    <news:publication_date>2025-03-15T09:00:00+00:00</news:publication_date>
    <news:title>Google Announces New SEO Update</news:title>
  </news:news>
</url>

How to Implement and Submit Your Sitemap

Once your sitemap is created, you need to implement it correctly and let search engines know it exists:

Step 1: Upload the File

Upload your sitemap.xml file to your site’s root directory (or another location of your choice).

Step 2: Reference It in robots.txt

Add a line to your robots.txt file pointing to the sitemap’s location:

User-agent: *
Sitemap: https://www.yoursite.com/sitemap.xml

If you have multiple sitemaps or a sitemap index, you can list them all:

User-agent: *
Sitemap: https://www.yoursite.com/sitemap.xml
Sitemap: https://www.yoursite.com/sitemap-images.xml
Sitemap: https://www.yoursite.com/sitemap-videos.xml

Step 3: Submit to Search Engines

Google Search Console:

  1. Go to Google Search Console

  2. Select your property

  3. In the side menu, click “Sitemaps”

  4. Enter your sitemap’s path (e.g., sitemap.xml)

  5. Click “Submit”

Google will show statistics about your sitemap’s processing, including the number of URLs discovered and indexed.

Bing Webmaster Tools:

  1. Log in to Bing Webmaster Tools

  2. Select your site

  3. Click “Settings” and then “Sitemaps”

  4. Add your sitemap’s URL

  5. Click “Submit”

Step 4: Verification and Monitoring

After submitting your sitemap, regularly monitor:

  1. Processing status in Google Search Console

  2. Indexing coverage (how many pages are actually being indexed)

  3. Any errors reported by search engines

According to a DeepCrawl study, 32% of sitemaps contain at least one error that can undermine their effectiveness. Constant verification is essential!

Best Practices and Optimization

To maximize your sitemap’s impact, follow these best practices:

1. Keep Your Sitemap Updated

Regularly update dates when content changes. Dynamic sites should generate sitemaps automatically, or at least weekly.

2. Compress Large Files

For sitemaps larger than 5MB, use gzip compression to reduce file size. Search engines accept compressed sitemaps (e.g., sitemap.xml.gz).

3. Structure Hierarchically

For complex sites, consider organizing your sitemaps by section or content type:

  • sitemap-products.xml

  • sitemap-categories.xml

  • sitemap-blog.xml

4. Prioritize Strategically

Use the element strategically:

  • Homepage and main pages: 1.0

  • Important categories and popular product pages: 0.8-0.9

  • Blog articles and secondary pages: 0.6-0.7

  • Support and policy pages: 0.4-0.5

5. Customize Change Frequencies

Set a realistic for each content type:

  • News pages or frequently updated content: “daily” or “hourly”

  • Product or category pages: “weekly”

  • Stable institutional pages: “monthly” or “yearly”

6. Integrate with Analytics

Compare your sitemap data with analytics tools like Google Analytics to identify:

  • Important pages that get little traffic (potential indexing issues)

  • Popular pages that aren’t in the sitemap (candidates for inclusion)

7. Test Before Submitting

Validate your sitemap using tools like:

Studies from Search Engine Journal show that sitemaps with no validation errors have up to 75% more pages correctly indexed.

Common Problems and Solutions

Even with careful planning, issues can crop up with sitemaps. Here are the most common ones and how to fix them:

1. URLs Not Indexed Despite Being in the Sitemap

Possible causes:

  • Low-quality or duplicate content

  • Crawling issues (check robots.txt)

  • Accidental noindex meta tags

  • Canonicalization problems

Solution: Use Google Search Console to check specifically for these URLs under “Coverage.” Often, GSC will give you the exact reason for the lack of indexing.

2. XML Format Errors

Possible causes:

  • Unescaped special characters

  • Malformed XML tags

  • Incorrect document structure

Solution: Use XML validators before submitting and make sure special characters are properly escaped (& should be &, etc.).

3. Blocked URLs Included in the Sitemap

Google Search Console will often flag this inconsistency.

Solution: Remove any URL blocked in robots.txt or with a noindex tag from the sitemap, or reconsider your blocking strategy.

4. Sitemap Too Large

Solution: Split it into multiple files using a sitemap index. Keep each individual file under 50MB and under 50,000 URLs.

5. Changes Not Being Detected

Possible causes:

  • Inaccurate or missing dates

  • Infrequent crawling by bots

Solution: Make sure modification dates are accurate and updated whenever content changes. Consider resubmitting the sitemap after major updates.

Measuring Your Sitemap’s Impact

To assess whether your sitemap is actually improving indexing, monitor these key indicators:

1. Indexing Coverage

In Google Search Console, compare the number of valid URLs submitted with the number of URLs actually indexed. A good indexing rate should be above 80%.

2. Indexing Time

For new content, measure how long it takes to appear in search results after publishing. Use GSC’s “URL Inspection” tool to check indexing status.

3. Organic Traffic

Compare organic traffic before and after implementing or optimizing the sitemap. Use segments in analytics tools to isolate the impact.

4. Crawl Coverage

Monitor server logs to check how much of your site is crawled daily/weekly, and compare it to periods before the sitemap was implemented.

According to data from Google I/O 2019, sites with well-implemented sitemaps can see up to 40% more pages discovered by search engines.

Advanced Indexing Strategies

Besides a good sitemap, consider these complementary strategies to improve indexing:

A Moz study found that pages three clicks or fewer from the homepage are 50% more likely to be well indexed. Improve your navigation structure to complement the sitemap.

2. Batch Indexing

For very large sites, submit URLs in batches through the Google Search Console API, prioritizing the most important ones first.

3. Schema Markup Implementation

Add structured data to your pages to help search engines better understand your content, which can lead to better indexing and rich snippets.

4. Accelerated Version

For sites with many content pages, consider implementing AMP (Accelerated Mobile Pages), which tend to be indexed faster.

5. Strategic HTTP Caching

Properly configure HTTP headers to tell search engines when and how often they should come back to check for updates.

Conclusion: The Sitemap as Part of Your SEO Strategy

An effective sitemap isn’t just an isolated technical document, it’s a central piece of a well-planned SEO strategy. It works as a direct communication channel with search engines, telling them what matters on your site and how it’s organized.

By following the practices detailed in this guide, you won’t just improve your site’s indexing, you’ll also optimize your “crawl budget,” making sure your most valuable pages get the attention they deserve.

As Google’s John Mueller pointed out in a webmaster hangout, “a good sitemap doesn’t fix fundamental SEO problems, but it can make a big difference for well-structured sites looking to maximize their visibility.”

In an increasingly competitive digital landscape, where visibility is the first step to success, a well-implemented sitemap can be the difference between being discovered and staying invisible in the vast ocean of internet content.

Once you’ve organized your own, it’s also worth comparing your sitemap with a competitor’s — a direct way to find topics and pages they have that you don’t yet.
