What Is Crawl Budget and how to optimize

crawl budget

First of all, let’s turn the familiar conversation that is repeated in the minds of many SEO experts into text:

SEO expert: Every time I post new content on my site or update a section, only a few weeks later I realize that search engines have not yet indexed these changes!

Search Engines: Didn’t I say don’t waste your site budget on 404 redirects and pages in vain!

SEO expert: What budget?

Search Engines: The same budget I have to use to index pages, Crawl Budget.

SEO expert: Does crawl have a budget? How do I find out what makes my site crawl budget less?

This is where the story of the formation of a concept called the Crawl Budget begins for us.

The Impact of Crawl Budget on SEO

What does Crawl Budget mean in SEO?

Crawl budget refers to the number of pages that search engine bots index on your site over a period of time (for example, one day). Your site budget is usually determined by the size and number of inbound links to it.

Crawl rate is the amount of attention that search engine crawlers pay to your site. The more attention you get, the more pages of your site will crawl and the pages of your site will be indexed faster.

Surely you are also thinking about how to get the most search engine attention to your site… but please do not rush, crawl rate optimization is an interesting and important issue, but to do it right we need to be more familiar with the Crawl Budget mechanism.

Why do search engines charge crawl rates for sites?

Let’s take a few steps back and talk about the main mission of search engines:

Delivering the best content to the user

In order for Google to be able to carry out this difficult but valuable mission, it needs to give a score to each site and based on this score, select the best one and provide it to the user. What is the first step to scoring?

The first step is for search engines to enter those sites (crawl to them!)

So, we can conclude that:

Allocating funds for crawl enables search engines to prioritize crawl rates. The better this prioritization is, the fairer the atmosphere for different sites to compete on the Internet.


What do search engines think about Crawl Budget?

Let the search engines look at the concept of crawl rates

Explain to you:

“First of all, the crawl rate is not something that worries you. If we assume that the content will be crawled and indexed immediately after release, then it does not make sense to worry about crawl rates.

If the number of pages on your site reaches several hundred, complete crawling of these pages is obvious and routine. “Determining what content to crawl and when to crawl, should be a concern for large sites with a large number of pages.”

Search engines do not suffice with this explanation and for a more detailed scrutiny of this concept, we are introduced to two new criteria.


How is the required budget of each site determined?

Search engines use two factors, Crawl Limit and Crawl Demand, to determine the required budget for each site.

Crawl limit / host load: How many crawls can our site server resources withstand?

As you know, every time search engines crawl a page, a request is sent to the server to access the site resources. If these requests are sent too much by search engine robots, the site server resources will not be able to respond to all of these requests and as a result the site will crash (or so-called down). How do search engines find out what the crawl capacity of our site is? In 2 ways:

Server Bug Signs: Search engine robots requests for crawling by the server have been encountered several times.

Number of active sites on the host: If your site is running on one of the shared hosts and there are hundreds of other sites active on these hosts and your site is large in terms of content and pages, then your crawl rate will be very limited.

If you are in this group, it is better to use specialized hosts to increase your crawl rate and improve page loading speed.

Crawl demand / crawl scheduling: Which page is worth crawling (or re-crawling)?

This value is measured based on the following factors:

Page popularity: How many quality internal and external links are given to this page and how many keywords are in it?

Content freshness: The content of the page is updated several times

Page type: For example, compare the category page with the terms and conditions page. Which one is more likely to have a change in content?


Why multiply Crawl Budget?

It may have happened to you that you are updating part of your site content, but after you published it, search engines crawled and indexed this change a few weeks later!

In some cases, even these changes are always hidden from the eyes of search engines and are never indexed. what is the problem?

Your site has a crawl rate. By comparing the following two cases, you will understand the importance of a healthy budget for your site.

Best Crawl Budget Scenario: When you add a page to your site, you expect search engines to index that page intelligently and quickly, without you having to ask the search engines to fetch that page. The faster this process happens, the faster you can get content from newly added (or updated) pages to the site.

Worst case scenario of Crawl Budget: If you are wasting your site crawl rate, search engine bots will not be able to crawl your site effectively. For example, they may focus more on pages of the site that do not matter to you.

This means that some of your target pages may never be recognized by search engines. If search engines do not recognize these pages, they will not be able to crawl and index them, and in this case, it will be impossible to receive organic traffic using search engine results.


Do you see where this scenario is heading to? Your website’s SEO may be ruined in the blackout!


Now let us prevent this catastrophic scenario by introducing several methods.

The impact of index and crawl on SEO

8 Irreparable Mistakes to Optimize Your Crawl Budget in The Worst Way!

“Crawl Budget optimization” simply means making sure that no budget is wasted on our site and that any crawl that search engine algorithms make for our site is used for a specific purpose (such as indexing an important landing page).


Fortunately, we’ve looked at the crawl budgets of many sites, and we can say with confidence that most of them suffer from similar problems. Simple but important problems that can cause your site to run out of budget.


Common reasons for losing a Crawl Budget are:

Existence of product filtering parameters in the URL: Store page addresses sometimes have parameters that the user uses to filter the product. For example, the address https://www.example.com/toys/cars?color=white.

Make sure that these parameters are not accessible to search engines and crawl, otherwise you will have to spend extra budget to index it.

Duplicate Content: Pages whose content is exactly the same or very similar are called duplicate content. Copied content, pages with identical titles, and duplicate tag pages are some of the most common. Copy content is usually ranked low in terms of indexing priority, so it does not make sense to use the budget to index them.

Poor content: Pages that contain cheap or no content should either not be placed on the site as much as possible or, if they do, should not be accessible to search engines. These pages can end up your site budget but do not add any value to your site!

Broken or Redirected Links: Broken or redirected links can confuse search engine robots like an infinite chain of links. The more confusion, the more budget is wasted. As far as possible, either do not use them or use them in accordance with the principles and in the right way.

Wrong URLs on the sitemap: Your sitemap is the most important access plan for search engine robots. If your sitemap is full of Broken or Redirected pages, search engines will crawl them incorrectly. We recommend that you do not include 3xx, 4xx or 5xx redirects in the xml map of the site as much as possible. Check your xml sitemap regularly to make sure:


  • It does not include worthless pages.
  • Target pages are present in it.


Pages with low loading speed: Pages that have low loading speed, or never load, have a negative effect on your site’s Crawl Budget. Because this signal to search engines that site servers cannot do well search engines intelligent robots requests. As a result, search engines reduce crawl rates so that requests can be processed correctly.


Lots of non-indexable pages: If your site has a lot of non-indexable pages, you are actually confusing search engines crawling them. Some site pages are not indexable.

Improper link building structure: If the overall internal link building structure of your site is unprincipled, search engine attention may not be properly distributed in different parts of the site.


For example, if you gave 10 links to the question-and-answer page but only 5 links to the product category page, that is, the question-and-answer page needs more attention from search engines. Surely you know that this is a mistake! Because the category page is more important than the question and answer. One of the most important issues in white hat SEO is internal link building.

Irreparable mistakes to increase the domain credibility and budget rate of the site

The most important questions that users have asked about the crawl rate of the site (but no one has answered them!)


In this section, we will put the most important questions that have been asked on the web about crawl rates but no one has answered them as a conclusion for you. The answers to some of them are in the content of the article, but here we want to review them briefly and usefully:


  1. How do I increase the crawl rate of my site?


Search engines have made it clear that there is a direct link between Page Authority, page validation and Crawl Budget. This means that the more credibility a page has, the more budget it has for Crawling. So, if you want to have more budget, you need to strengthen the credibility of your page or domain. To strengthen your domain reputation, the best starting point is to look at the Domain Credibility Enhancement article to become fully acquainted with the methods and techniques of domain enhancement.


  1. What effect does site speed and number of errors have on the Crawl Budget?


In terms of search engines, a high-speed site is a sign that its servers are healthy. As we said in the Crawl Limit section, server health is one of the signs of higher crawl rates. The opposite is also true; This means that if the request to the server has many errors, the crawl rate will go down.


  1. Is crawl an influential factor in SEO?


A high number of crawl rates has no effect on improving the position on the results page. Search engines use 200 factors to evaluate the quality of sites and although the crawl rate is essential for ranking but it is not part of the ranking factors.


  1. Can I use the canonical tag to better crawl my site?


It is good to mention the difference between crawl and index here. Using the canonical tag gives search engine robots a signal that the page is not indexed. But you have to pay attention to the fact that understanding this issue in terms of search engines requires crawl, and we can say that the use of focal tags has no effect on the amount of crawl. We suggest you to read the article “What is a canonical tag” to understand this better.


Now it’s time for your valuable comments. What experience have you had with your site’s crawl rate? How did you solve the problems that Crawl Budget created for you? Sharing your experience may solve someone’s problem.
