You’re not the only one who has ever questioned why some of your website pages appear in Google while others do not.
Behind the scenes, search engines rely on a process called crawling to discover and evaluate web content. That brings us to an important SEO concept you absolutely need to understand – What is Crawlability?
Let’s break it down.
What is Crawlability?
The term “crawlability” describes how simple it is for search engine bots, such as Googlebot, to navigate and access the pages on your website.
When your site is crawlable, it means these bots will explore your content, follow internal links, and send all that information back to search engines for indexing.
However, those bots will completely ignore specific sections of your website if they are blocked, too deep in your structure, or take a long time to load.
Consider crawlability as allowing Google to access your website. Bots can easily explore, if the doors are wide open and the hallways are well-lit. However, your content will never be found if there are dead ends, damaged stairs, or locked doors.
How Web Crawling Works?
So, how do search engines work? It starts with bots also called spiders or crawlers crawling the web to find content.
These bots follow links from one page to another, gathering data and sending it back to the search engine’s servers.
If bots can crawl your website, they can:
- Access your pages,
- Understand the content and structure,
- Decide which pages to index.
However, if your website contains problems, such as broken links or improper directives, those pages might never be viewed or ranked.
Crawlability vs Indexability: What’s the Difference?
Despite sounds similar, these two terms play very different roles in SEO. To clear up any doubt, here is a brief explanation:
| Feature | Crawlability | Indexability |
|---|---|---|
|
What it means |
The ability of search engine bots to access and navigate your website pages. |
The ability of your pages to be stored and included in a search engine’s index.
|
|
How it works
|
Bots like Googlebot follow links and crawl content. |
Once crawled, pages are evaluated and potentially added to the search index.
|
|
Common blockers
|
Broken links, blocked robots.txt file, slow loading pages
|
“noindex” directives, canonical tags, or duplicate content
|
|
Goal
|
Ensure bots can reach and read all valuable content.
|
Ensure important pages are eligible to appear in search results.
|
However, be careful when using a robots meta tag. It might stop your page from getting indexed, even if search engines can crawl it.
Always double-check your settings, especially on important pages you don’t want to accidentally hide.”
Factors That Affect Crawlability
Now that we have got a clear picture of what crawlability means. Let’s discuss what genuinely affects it.
The following are the primary factors that affect of your site’s ease of crawlability:
1.Robots.txt file
Robots.txt file is like the bouncer at the door. If it says “no entry,” Googlebot won’t crawl those pages. Verify that you’re not accidentally blocking important sections of your site.
2.Crawl Errors
Crawl Errors means Broken links, server errors, or incorrect redirects. For search engine bots, these are similar to tripping hazards. They can confuse crawlers and stop them in their tracks. You can identify and address these problems by routinely auditing your website.
3.Site Structure
Bots can move between pages with ease when there is a clear and logical hierarchy. Crawlability worsens if your website is a complicated web of links.
4.Internal Linking
Strong internal links are like useful road signs. They guarantee that no page is left behind and direct crawlers deeper into your website.
5.Robots meta tag
In contrast to the robots.txt file, this establishes guidelines for groups of pages. This tag instructs search engines on how to handle specific pages, including whether or not to index them. So, make good use of it.
6.Crawl Budget
Google has a limited amount of time to explore your website. As your site grows in size, making the most of your crawl budget by giving priority to high-value sites becomes increasingly crucial. Consider it like giving bots a curated tour of your most important content.
7.Site Speed and Server Performance
Bots will abandon the crawl midway, if your site takes forever to load or your server keeps timing out. Fast and reliable hosting goes a long way.
Each of these factors plays a role in how smoothly search engines can crawl your site. The better the crawlability, the better your chances of getting indexed and ranked.
Best Practices to Maintain Crawlability
How do you maintain your website so that search engines can effectively crawl it over time? Consider this like routine website maintenance. You should take routine actions to ensure that bots will continue to navigate your website without any issues, much like you would with a car.
To help you stay on top of it, consider the following recommended practices:
- Keep Your robots.txt File Clean and Up-to-Date: Only pages that you really don’t want crawled, like internal admin pages or staging environments, should be blocked by your robots.txt file. Review it regularly, especially after site updates or migrations.
- Fix Crawl Errors Promptly: Don’t disregard Google Search Console’s crawl error reports. These problems can prevent bots from accessing important areas of your website.
- Optimize Internal Linking: For both users and crawlers, internal links serve as helpful road signs. Bots will find your site easier to navigate if it is more connected and logical.
- Manage Your Crawl Budget Wisely: Search engines don’t have unlimited resources to crawl every single page of your site, particularly if you have a large one. So use the crawl budget smartly.
- Maintain a Simple and Logical Site Structure: Maintain a simple and easy-to-use site architecture. For both crawlability and user experience, a shallow structure is best, with all pages accessible within three clicks of the homepage.
- Monitor Site Speed and Server Health: Bots don’t wait for pages that load slowly. The amount of content that is crawled and indexed will be limited by a slow website.
- Use XML Sitemaps and Keep Them Updated: An XML sitemap is similar to giving Google your website’s roadmap. It makes sure nothing is missed, especially fresh content and indicates which sites are crucial.
- Use Canonical Tags Properly: Google knows which version is the “main” one to crawl and index with the help of canonical tags, in the case if you have pages with very similar content or multiple versions like product filters.
- Check for Mobile Crawlability: Now that mobile-first indexing is the norm. So, the crawlability of your mobile website should be equal to that of your desktop version.
