Sitemap Overview

Sitemap essentials: Your guide to website navigation optimisation

Published on at Technical SEO blog by .

I understand that a sitemap is a fundamental element of a website’s architecture, acting essentially as a map that guides search engines through the site. It enables these engines to locate and index content more efficiently. This can be particularly beneficial for new or updated pages that might not yet be well-linked through the site’s navigation structure.

There are several types of sitemaps, and they serve different purposes.

The XML sitemap, for instance, is specifically formatted for search engines. It lists URLs along with additional metadata about each page such as the last update, the frequency of changes, and its importance relative to other pages on the site. This makes it easier for search engines like Google to crawl my site more intelligently and efficiently.

On the other hand, HTML sitemaps are designed for human visitors, helping them to understand and navigate the structure of my website.

Creating an effective sitemap requires an understanding of my website’s content and structure, as well as the requirements of the search engines I wish to target.

It’s a strategic component of my website’s SEO and user experience, and it’s something I make sure to keep updated to reflect the most current layout of my site.

Whether I am handling a large e-commerce platform or a small blog, a well-planned sitemap is an integral part of ensuring that all the content on my site can be found and ranked by search engines and, by extension, by the audiences searching for it.

Importance of sitemaps

In my experience, sitemaps play a critical role in optimising a website for search engines like Google and Bing. They serve as a foundation for your site’s SEO strategy and ensure efficient crawling by search engine bots.

SEO benefits

Sitemaps are fundamental in SEO as they guide search engines through a website’s structure, highlighting which pages are a priority. They act much like a blueprint, allowing Google and Bing to easily locate and index all of your website’s content. In particular, sitemaps are beneficial because they:

  • Help search engines understand the organisation of your site
  • Indicate the most important pages, improving the likelihood of ranking higher in search results
  • Enhance the discovery of pages that might not be easily found through regular crawling processes

Enhancing indexing

Sitemaps improve the indexing process by ensuring that search engines can more intelligently crawl your site. They are particularly useful for:

  • Large websites with many pages, where search engines may overlook some of the content without a sitemap
  • New websites with few external links pointing to them, aiding search engines in discovering their content
  • Websites with a lot of rich media content, such as videos and images, which may be beneficial for search engine results

By incorporating a well-structured sitemap, I make certain that Google and Bing can easily identify and index the content on a website, which can significantly impact its visibility in search results.

Types of sitemaps

In addressing the various types of sitemaps available, I focus on their distinct roles in enhancing a website’s SEO and usability. These maps serve as a navigational aid, not only for users but also for search engines, ensuring content is found and indexed effectively.

XML sitemaps

My initial focus is XML sitemaps, crucial from an SEO perspective.

An XML sitemap is essentially a roadmap allowing search engines to navigate a site intelligently. This XML file lists all web pages that you wish to make visible to search engines, like a master index. A typical sitemap.xml file can include URLs, the relative importance of pages (priority), and the frequency of updates (change frequency), aiding in more efficient content discovery and indexing.

HTML sitemaps

HTML sitemaps serve a user-focused role.

Unlike an XML sitemap, an HTML sitemap is a webpage that links to all important sections and pages within the site, providing a navigational aid to users. It allows visitors to quickly find content on your site and helps search engines to understand site structure when complementing an XML sitemap.

Image sitemaps

Moving on to image sitemaps, these are specialised XML sitemaps containing metadata about the images present on a website.

By making use of an image sitemap, you assist search engines in finding images that might be otherwise difficult to discover, especially if they are loaded through JavaScript or housed in galleries. This type of sitemap can be particularly beneficial for visual-centric websites.

Video sitemaps

Video sitemaps are akin to their image counterparts but focus squarely on video content.

These sitemaps provide search engines with details like video title, description and duration. The use of a video sitemap ensures that rich video material is appropriately indexed and boosts the likelihood of appearing in video search results.

News sitemaps

With news sitemaps, I’m able to say that they are tailored for websites that regularly post news articles.

A news sitemap makes it possible for such content to appear in Google News by including information like the publication date, name, and unique keywords. This form of sitemap is essential for news outlets wanting to increase their visibility within news search results.

Creating a sitemap

Creating an effective sitemap is an essential step for ensuring that search engines can more accurately crawl and index a website. It involves using specific tools or methods to generate a structured list of pages.

Let’s explore the most common ways to create a sitemap: through generators, WordPress plugins, or manual creation.

Sitemap generators

A sitemap generator is a useful tool to automatically create a sitemap.xml file for a website.

For example, is an online generator that provides a free service to create XML sitemaps which can then be submitted to search engines.

The process is straightforward: enter your full website URL, configure some optional parameters, and let the generator do its work. Once the sitemap is created, it should be placed in the root directory of your website.

WordPress plugins

For websites built with WordPress, plugins can simplify the process of sitemap creation.

Notable WordPress plugins like Yoast SEO and Rank Math SEO include sitemap features.

These plugins automatically create an XML sitemap and update it whenever new content is published. They provide a hassle-free solution and often include additional SEO tools that are beneficial for website visibility.

Manual creation

For those who prefer a hands-on approach or have special requirements, manual creation of a sitemap is possible.

I would start by listing all website URLs in a spreadsheet to create an HTML version, which benefits users as a navigation aid, or visual sitemap for design and planning purposes. Then, I’d define the structure in XML format for search engines.

Although this method can be time-consuming, it offers full control over the contents and structure of the sitemap.

Sitemap best practices

When managing sitemaps, it’s crucial for me to adhere to specific best practices to ensure search engines like Google can effectively crawl and index my website’s content. This includes proper formatting of the XML file, routinely updating the sitemap, and maintaining the size limits prescribed by the protocols.

Correct formatting

The cornerstone of a sitemap is its accurate XML formatting.

I ensure that my sitemap adheres to the XML protocol, with each URL entry enclosed in <url> tags, and components like <loc>, <changefreq>, and <lastmod> properly defined.

This structure helps search engines decipher the information more efficiently for crawling. For a sitemap index, which is a collection of sitemaps, I use sitemap_index.xml to consolidate and organise multiple XML files.

Updating sitemaps

To keep the sitemap relevant, I update it regularly as new content is added to my site.

I include the <lastmod> tag to signal to search engines the last modification date of the content.

This demonstrates to Google that my website is current and can influence how often it chooses to crawl my pages. Regular updates to the sitemap align with the dynamic nature of my content, making it easier for search engines to find and index new pages.

Size of sitemap

I am aware that there are limits to how large a sitemap can be.

A single sitemap must not exceed 50MB (uncompressed) and should contain no more than 50,000 URLs. Usually, I split into 1000 URLs in sitemaps to ensure fast loading.

For larger sites, I utilise a sitemap_index.xml file that points to individual sitemaps, ensuring no single sitemap breaches these thresholds.

By adhering to these size constraints, I prevent any issues with search engines processing my sitemap efficiently.

Integrating sitemaps with search engines

In order to ensure that both Google and Bing search engines index and serve my website’s content in search results effectively, I integrate sitemaps using their webmaster tools.

Google Search Console

To facilitate the indexing process for Google’s search engine, I submit my sitemap to Google Search Console.

This is paramount to guarantee that my site’s pages are included in Google search results. The console allows me to submit multiple sitemaps and even sitemap index files, which is beneficial for monitoring the search performance of each sitemap individually.

I ensure my sitemap file is UTF-8 encoded and follows the format requirements set by Google.

After submission, I can check the status within the console to confirm that Google has processed my sitemap successfully.

Bing Webmaster Tools

For Bing, I use Bing Webmaster Tools to submit my sitemap.

This helps Bing’s search engine to discover and index my website’s pages.

The process is straightforward: by accessing my Bing Webmaster Tools account, I select the ‘Sitemaps’ from the dashboard and enter the URL of my sitemap.

I pay close attention to Bing’s requirements, ensuring that my sitemap conforms to the recommended protocol. After submission, Bing provides feedback indicating whether the sitemap has been indexed successfully.

Technical considerations

In addressing the technical aspects of sitemaps, my focus will be on the crucial role that robots.txt plays in conjunction with these sitemaps. I’ll also touch upon elements that aid in optimising the crawl process, such as sitemap generators and common issues like broken links.

Robots.txt and sitemaps

Robots.txt is a text file at the root of my website that informs search engine crawlers which parts of my site they can or cannot request from my server via the robots exclusion standard.

By specifying the path to my sitemap within the robots.txt file, I ensure that search engines can easily locate and crawl my sitemap, thereby facilitating better indexing of my site.
