What is crawlability, and why is it important for search engine optimization (SEO)?
Crawlability refers to a website’s ability to be crawled and indexed by search engine bots. When a search engine bot crawls a website, it looks for relevant content and backlinks to other pages and websites, which helps search engines understand the context and relevance of a site’s content. Search engines use sophisticated algorithms to analyze a website’s content and structure to determine its relevance to a particular search query. The more easily a site’s crawlability and indexability are, the higher the likelihood it will appear in search results for relevant queries.
This article will discuss crawlability and how to improve it to help websites rank better in SERPs. We will explore the primary factors that impact crawlability, best practices for improving crawlability, and the tools that can be used to evaluate crawlability. By the end of this article, website owners will know why is crawlability important? and how internal linking can improve it, resulting in higher search engine rankings and more organic traffic.
Let’s look at some elements that affect crawlability.
Factors Affecting Crawlability of a Website

Several factors can impact a website’s crawlability. Understanding these factors is essential to improve crawlability, which can help websites rank higher in SERPs. The following are the primary factors that impact crawlability:
Website structure:
The structure of a website is crucial to its crawlability. A website should have a clear and simple structure that makes it easy for search engine bots to crawl and index pages. A well-designed website should have a logical hierarchy of pages and a clear navigation menu. On the other hand, a bad site structure can wreak havoc on your site’s crawlability.
Robots.txt file:
A robots.txt file tells search engine bots which pages of a website to crawl and which ones to ignore. Creating a crawl-friendly robots.txt file is essential to ensure that important pages are crawled and indexed. However, mistakes in this file can prevent other search engines from crawling important website pages. For example, if you restricted to crawl a certain page, search engines can’t crawl and index that page because they won’t be able to access.
XML sitemap:
An XML sitemap is a file that lists all the pages on a website, making it easier for search engine bots to crawl and index them. It helps search engine bots discover new pages or changes to existing pages, improving the website’s crawlability.
HTTP status codes:
HTTP status codes are messages web servers send to web browsers and bots to provide information about a web page’s status. HTTP status codes indicate whether a page is successfully loaded or an error occurred. Common error codes include 404, 500, and 301. Errors can negatively impact a website’s crawlability.
JavaScript and AJAX:
Search engine bots may have difficulty crawling JavaScript and AJAX content. It’s important to ensure that the website’s JavaScript and AJAX are search-engine friendly. If Googlebots find difficulty crawling, they’ll leave your site.
Optimize Your Site for Improving Crawlability and Indexability

Improving crawlability can help websites rank higher in search engine results pages. There are several best practices to improve crawlability, which include:
Optimizing website structure and navigation:
A website should have a clear and simple structure that makes it easy for search engine bots to crawl your site and index pages. The website structure should be easy to navigate and have a clear page hierarchy. Search engines won’t likely crawl pages that aren’t linked to from anywhere on your site.
Creating a crawl-friendly robots.txt file:
A well-designed robots.txt file helps search engine bots crawl important pages and avoid irrelevant ones. It’s important to avoid mistakes in this file that can prevent search engines from crawling important website pages.
Generating and submitting an XML sitemap:
An XML sitemap provides search engine bots with a complete list of pages on a website, making it easier to crawl and index pages. Submitting this file to search engines can improve the website crawlability.
Avoiding duplicate content and canonicalization issues:
Duplicate content and canonicalization issues can confuse search engine bots and negatively impact crawlability. Use canonical tags to indicate the preferred version of a page and avoid duplicate content within the website’s root directory.
Using structured data markup:
Structured data markup provides search engines with additional information about the internal link structure, making it easier to understand and index. This helps web crawlers improve the website’s crawlability.
Minimizing page load times:
A slow page load can negatively impact web crawler access. Optimizing images, browser caching and internal links, and a content delivery network (CDN) minimises page load times. A faster page load time makes it easier for search engine bots to crawl web pages, resulting in improved crawlability and indexability for SEO.
SEO Tools for Evaluating Crawlability

Several tools can be used to check a website’s crawlability and to rectify problems related to it. These include:
Google Search Console:
Google Search Console is a free tool that provides valuable insights into a website’s crawlability. It allows website owners to index your site on Google, submit your sitemap, see crawl errors for each URL, sitemap submission status, and other information about their website’s performance on Google searches.
Crawling tools like Screaming Frog and DeepCrawl:
Crawling tools help identify crawl errors, duplicate content, and other issues impacting crawlability. These tools scan test a website to provide detailed information about crawlability issues for different pages on your site and recommendations for improvement.
SEO auditing tools like Ahrefs and SEMrush:
SEO auditing tools can help to identify crawlability issues and provide recommendations for improving them. They also help you create new content that will help you solve the overall crawlability problems. You can find follow links, get a comprehensive overview of a website’s performance on search engines, and identify areas for improved technical SEO.
Conclusion
Crawlability is a critical aspect of SEO that cannot be overlooked. It’s essential to ensure that a website is easily crawlable and indexable by search engine bots. By improving crawlability, owners can ensure that their website’s pages are crawled and indexed by search engine bots, leading to higher search engine rankings and more organic traffic. With the help of the right tools and best practices, improving crawlability is achievable for any website owner, regardless of their technical expertise.
By optimizing website structure, creating a crawl-friendly robots.txt file, generating an XML sitemap, avoiding duplicate content and canonicalization issues, using structured data markup, and minimizing broken links and page load times, you can improve your site’s crawlability, making it easier for Google’s bots to crawl and index their pages, resulting in more organic traffic and higher search engine’s ability.
