Website crawling is what happens when search engine bots visit web pages and try to understand what a page is about and the possible value it provides. It is the first process of indexing your web pages. The process involves determining the number and type of pages that exist on your website.
Website crawling can be controlled by the website admin using robot.txt files to tell search engines pages to exclude or include in crawling as well as those to index. Using internal linking is a good method to allow Google bots to follow your internal link to other pages of your website and determine its relevance. It is a good method to increase page authority and relevance.
Web pages with greater and more relevant links are awarded more value and relevance than those with little or no links. They are therefore better crawled than those without internal links on a website.

- The use of proper tags and meta data

- The use of descriptive H1, H2, and H3 tags
- The use of Effective Image Alt tags
- Proper use of CSS, fonts, and multimedia
- The absence of duplicate content
- Content quality and relevance in comparison with other pages on the web

What are Website Crawlers?
Website crawlers are a vital part of any SEO strategy. They help you index your content properly, identify broken links, and identify pages that need improvement. They also help you identify potential competitor content, and see what changes you may need to make to stay ahead of the competition. No matter what your website needs, a crawler can help you get the job done quickly and easily.
A website crawler is software or a bot that helps you index and crawls the pages of a website. This is important because it allows you to extract all the data and information on the website. This data can then be used to improve your search engine rankings, create better content, and identify potential business opportunities.
What are the Two Main Types of Website Crawlers?
There are two main types of website crawlers – crawling robots and web scraping robots. Crawling robots are used to index and collect data from websites. Web scraping robots are used to collect data from websites by extracting data from the pages and files on the website.
Crawling robots includes both search engine robots that crawl web pages to index them as well as personal robots that are used to gather information about specific websites on the web.
According to Cloudflare, the most active crawling bots are search engine bots and include the following:
- Google: Googlebot (actually two crawlers, Googlebot Desktop and Googlebot Mobile, for desktop and mobile searches)
- Bing: Bingbot
- Yandex (Russian search engine): Yandex Bot
- Baidu (Chinese search engine): Baidu Spider
Website scrapping robots are a great way to get your website up and running quickly and efficiently. These tools automatically collect all the content from a website and create a unique, keyword-rich file that can be used to promote your website on Google, Bing, and other search engines.
This is a powerful tool for getting your website online quickly and increasing your online visibility. Not only does this help you to dominate the search engine results pages (SERPs), but it can also help you to attract new visitors to your website. Once your website is up and running, using a scrapping robot can help you to keep it updated and fresh with the latest trends and marketing techniques.
Other personal or commercial website crawlers are tools like Screaming frog which are useful for technical SEO analysis of a website.
How to Optimize Robot.txt files for Efficient Crawling of Websites
When searchers search for terms or phrases on search engines, information is extracted from relevant sites and displayed as search engine result pages (SERP), this is achieved by indexing web pages by search engine bots which is possible by allowing search engine bots like Google bots to crawl your website or certain pages on your website. Optimizing your robot.txt file is a very important aspect of crawling and indexing.
Choosing to allow certain pages to be crawled and some never to be crawled and indexed can be achieved using the robot.txt file on your website. Using this file, specific instructions can also be given to specific search engine bots that are allowed to crawl a page.
The file on your server which allows the crawling of certain pages on your website while also identifying those that are not allowed but it to be crawled or requested is referred to as robot.txt file. It is one of the significant aspects of your website files as it helps to prevent bots from overrunning your website.
The robot.txt file is useful for keeping certain pages entirely out of SERP, for such purposes, no index option on your SEO plugin is usually selected when such pages are published.
It is very useful for the management of web traffic such as hiding some web pages from SERP to avoid too many requests which may slow down your website.
The robot.txt file is also useful for preventing certain images or videos from becoming a part of SERP and for blocking scripts or images files that are not important as well as for preventing the indexing of certain pages such as login pages, broken links, duplicate contents, XML sitemap and thereby increases your website value by no-indexing irrelevant pages that may reduce your website relevant as may be determined by search engines bot. This also plays a very important part in ranking,
How Robot.txt Files Work
When search engines send out robots to crawl and index some web pages on your website, they receive instructions from your robot.txt file on your server about which pages or certain aspects of the pages to crawl and index and which not to, robot.txt files achieve this by allowing and disallowing certain commands on your robot.txt file. This command is important for crawling of pages.
The disallow command contains information such as pages or parts of a page that should not be crawled n=and indexed. For example, the user-agent* command identifies specific crawlers while Disallow: /images/ instructs the crawlers not to crawl and index the image on the page. Commands such as Allow: gives general access to various search engine bots while others such as Allow:/Bingbot only allow Bing bot to index the web page.
Allow:/Bingbot implies that only Bing bot will be allowed to crawl and index the page, this is usually as bad SEO practice except in situations where leads and traffic generation is not the goal, in most cases, it is important to allow search engines bots access and not only one search engine bot, this can result to a drastic decrease in traffic especially if it\’s an important page that has great potential for ranking.
How to Create Robot.txt Files
The Rank Math SEO plugin is one of the many SEO plugins such as Yoast and All-in-one SEO plugin that has made the job of creating robot.txt file very easy and so there is no need to use a developer as this can be easily done or achieved in a few steps by using the plugin.

Website crawling is an important part of web analytics, and it is responsible for indexing and reporting on the crawl status of all the pages on a website. This information helps in understanding the website’s traffic flow, Bounce Rate, Time on Site, and a variety of other important factors.
Website crawling also helps in detecting broken links and issues with the website’s content that might be causing poor user experience. By fixing these issues, you can improve the website’s ranking in search engines, which will attract more visitors. Additionally, website crawling can help you to identify new and potential marketing opportunities by identifying content that is being shared and liked on social media.
How Search Engines Index Pages
Indexing is the process of assigning a ranking to a website page so that it can be found by a search engine user. There are many factors that play into how a website page is indexed, but the most important factor is the amount of authority that the page possesses.
The more authoritative the page, the higher it will rank in search engine results pages (SERPs). This is because search engines use data from a variety of sources to determine how to rank a page. These sources include:
- The number of incoming links to the page
- The length of the page
- The type of content on the page
- The relevance of the page to the search query
In order for a website page to be found, search engines must index it. This is done by adding the page to an index and making it available to be searched.
When a user types in a query into a search engine, the search engine looks through its index of websites to see if it can find the requested page. If it can, the search engine will return the page to the user.
There are many factors that search engines use to determine which pages to include in their index, including the importance of the page, the popularity of the page, and the site’s history.
A page that is important to the users of a search engine may be given a higher priority than a page that is popular but not important. In addition, a page that has been updated recently may be given a higher priority than a page that has not been updated in a while.
