Crawlability; Indexability: How They Affect SEO

SEO is one of the most important marketing tools for websites. It’s a way to bring in more money by driving traffic to your website and letting people find what they are looking for on the internet. However, there has been a recent debate about how crawlability and indexability affect SEO, with some saying it doesn’t matter since Google still ranks you as high if you have great content but low crawlability or indexable pages.

The “crawlability test” is a tool that helps you to determine the crawlability of your website. The indexability test will help you to determine how easy it is for search engines to find the content on your website. This article does a great job at explaining both of these tests and their importance.

Tell me, when you think about rating a website, what’s the first thing that springs to mind?

Content? Backlinks, perhaps?

Both are, without a doubt, important variables in determining a website’s rank in search results. They aren’t the only ones, however.

In reality, crawlability and indexability are two more important elements in SEO. Despite this, the majority of website owners have never heard of them.

At the same time, even minor indexability or crawlability issues might cause your site to lose ranks. That is true regardless of how good your content is or how many backlinks you have.

What is the difference between crawlability and indexability?

Let’s look at how search engines find and index sites to have a better understanding of these phrases. They utilize web crawlers, which are bots that follow links on the web with one purpose in mind: to learn about each new (or updated) website.

New online material must be discovered and indexed.

According to Google:

“Crawlers look at websites and follow links on those pages in the same way that you would if you were surfing the web for information. They hop from link to link, sending information about the websites to Google’s computers.”

Matt Cutts, a former Google employee, created an informative video that explains the procedure in detail. You may see it here:


In a nutshell, both of these concepts refer to a search engine’s capacity to access and index pages on a website in order to add them to its index.

The capacity of a search engine to access and crawl material on a website is referred to as crawlability.

If a site is crawlable, web spiders may readily access all of its content by following connections between pages.

Crawlability difficulties – the search engine’s inability to reach certain material on a site – may be caused by broken links or dead ends.

The capacity of a search engine to examine and add a page to its index is referred to as indexability.

Even if Google is able to crawl a website, it may not be able to index all of its pages owing to indexability concerns.

What factors have an impact on crawlability and indexability?

1. The Organization of the Website

The crawlability of a website is determined by its informative structure.

Web spiders, for example, may have trouble accessing pages that aren’t linked to from anyplace else on your site.

They might, of course, still reach such sites through external links if someone mentions them in their material. However, a shaky structure as a whole may generate crawlability concerns.

2. Internal Linking System

A web crawler navigates the internet by clicking on links, just as you would on any page. As a result, it can only locate pages from other material that you link to.

As a result, a solid internal link structure will enable it to rapidly access even the deepest pages inside your site’s structure. A bad structure, on the other hand, might lead to a dead end, causing a web crawler to overlook portions of your material.

3. Redirect Loops

Crawlability difficulties would be caused by broken page redirects, which would halt a web crawler in its tracks.

4. Errors on the Server

Broken server redirection, as well as a variety of other server-related issues, might prohibit web spiders from accessing all of your material.

5. Scripts that aren’t supported and other technological issues

Crawlability difficulties might also be caused by the technologies you employ on your website. Gating material behind a form, for example, will cause crawlability concerns since crawlers can’t follow forms.

Scripts such as Javascript or Ajax may also prevent web spiders from accessing material.

6. Preventing Web Crawlers From Accessing Your Site

Finally, you may prevent web spiders from indexing your site’s pages.

And there are some compelling reasons to do so.

For example, you may have built a page that you wish to keep private. You should also restrict it from search engines as part of limiting that access.

However, it’s possible to accidentally block other sites as well. A single coding mistake, for example, might cause the whole area of the site to be unavailable.

This article – 18 Reasons Your Website is Crawler-Unfriendly: Guide to Crawlability Difficulties – has a comprehensive list of crawlability issues. 

How can a website be made to be simpler to crawl and index?

Some of the variables that might cause crawlability or indexability concerns on your site have previously been mentioned. As a result, as a first step, you should make certain they do not occur.

There are, however, some steps you may take to ensure that web spiders can readily reach and index your content.

1. Submit a Google Sitemap

A sitemap is a short file that lives in the root folder of your domain and provides direct links to all of your site’s pages, which it uploads to Google via the Google Console.

The sitemap informs Google about your content and notifies it of any changes you’ve made.

2. Make Internal Links Stronger

We’ve previously discussed the impact of interlinking on crawlability. As a result, enhance linkages between pages to guarantee that all material on your site is related to raise the odds of Google’s crawler discovering all of it.

3. Update and add fresh material on a regular basis.

The most crucial aspect of your website is its content. It assists you in attracting visitors, introducing your company to them, and converting them into customers.

Content, on the other hand, aids in the crawlability of your site. For one thing, web spiders pay greater attention to sites that are continually updating their material. As a result, they’ll crawl and index your website considerably more quickly.

4. Do not duplicate any stuff.

Duplicate content, or pages with the same or extremely identical information, might cause a drop in ranks.

However, duplicating material might reduce the number of times crawlers visit your site.

As a result, go through the site for any duplicate content concerns and repair them.

5. Reduce the time it takes for your website to load.

Crawlers normally only have a limited amount of time to crawl and index your site. The crawl budget is what it’s called. And when that timer expires, they’ll just quit your site.

As a result, the faster your pages load, the more of them a crawler may visit before running out of time.

Don’t be alarmed if all of the foregoing seems daunting. There are tools available to assist you in identifying and correcting crawlability and indexability problems.

What they don’t realize is that their efforts will be for nothing if search engines’ crawlers are unable to index and scan their sites.

That’s why, in addition to working on adding and optimizing pages for important keywords and establishing connections, you should always check to see whether web crawlers can reach your site and report back to the search engine what they discover.
