I don’t know you, but I won’t describe myself as a “technician.” In fact, the technical aspects of marketing are usually the hardest for me to conquer.

To that moment Technical search engine optimization, It may be difficult to understand how this process works. But it is important to acquire as much knowledge as possible to optimize our website and attract more audiences. One tool that plays an important role in search engine optimization is the web crawler.

In this article, we will learn What is a web crawler, How they work, with Why they should crawl your website.

You may want to know, “Who runs these web crawlers?”

Generally, web crawlers are operated by search engines with their own algorithms. The algorithm will tell web crawlers how to find relevant information in response to search queries.

A web spider will search (crawl) and classify all web pages on the Internet that it can find and be told to index. Therefore, if you don’t want to find your webpage on search engines, you can tell web crawlers not to crawl your webpage.

To do this, you need to upload a robots.txt file. Essentially, the robots.txt file will tell search engines how to crawl and index the pages on your website.

For example, let’s look at Nike.com/robots.txt for visual learners.

Nike robots.txt instructs web crawlers to index content

For Nike, it uses its robots.txt file to determine which links on its website will be crawled and indexed.

The Nike robots.txt file instructs the web crawler to allow crawling of seven pages and prohibit crawling of three pages

In this part of the document, it determines:

  • Web crawler Baiduspider is allowed to crawl the first 7 links
  • The web crawler Baiduspider is banned from crawling the other three links

This is good for Nike, because some of the company’s pages are not intended for search, and disallowed links will not affect its optimized pages that help them rank in search engines.

Now that we know what web crawlers are, how do they work? Next, let us review how web crawlers work.

The web crawlers of search engines will most likely not crawl the entire Internet. Instead, it will determine the importance of each page based on factors such as how many other pages link to that page, page views, and even brand authority. Therefore, the web crawler will determine which pages to crawl, the order in which they are crawled, and the frequency of crawling updates.

For example, if you have a new webpage, or make changes to an existing webpage, the web crawler will record and update the index. Or, if you have a new page, you can ask search engines to crawl your website.

When a web crawler is on your page, it looks at the copy and meta tags, stores that information, and indexes it so that Google can sort the keywords.

Before the whole process begins, the web crawler will look at your robots.txt file to see which pages to crawl, which is why it is so important for technical SEO.

Ultimately, when a web crawler crawls your web page, it will determine whether your web page will be displayed on the search results page of the query. It is important to note that some web crawlers may behave differently from other web crawlers. For example, when deciding which pages are the most important to crawl, some people may use different factors.

Now that we understand how web crawlers work, we will discuss why they should crawl your website.

Why is website crawling important?

If you want your website to rank in search engines, you need to index it. Without a web crawler, even if you search for paragraphs taken directly from your website, you will not find your website.

Simply put, your website does not exist unless it is crawled once.

To find and discover links on the web through search engines, you must enable your website to attract its target audience by crawling it—especially if you want to increase organic traffic.

If the technical aspects of this are confusing, I understand.This is why HubSpot has a Website Optimization Course It expresses technical topics in simple language and guides you on how to implement your own solutions or discuss these issues with your network experts.
