Web crawling has a wide range of applications that businesses can leverage to gain a competitive advantage. Most notably, it is integral to the functionality of search engines as well as the results displayed for every query. It is also worth noting that as a business, you can independently use web crawler tools to collect data or verify that your website and the pages therein are crawlable. This article will analyze web crawling from the latter perspective and detail how web crawlers can generally benefit your business. Firstly, though, let’s discuss what is a web crawler.
What is a web crawler?
A web crawler/spider/spiderbot is a program that follows links embedded in web pages to discover new web pages and content. This act of following links is what is referred to as web crawling. At the same time, however, the spiders also collect and store the content found in the crawled web pages for future retrieval. The process of storing the data in databases is known as indexing.

Importance of web crawlers for businesses
Search engine bots discover web pages and, through the process, facilitate the eventual ranking of websites on search engine results pages (SERP). Typically, the ranking is subject to the fulfillment of certain preconditions that, together, inform sites’ search engine optimization (SEO) strategies.
It is worth noting that some elements of SEO, such as the use of links, regular content, and use of keywords, are meant to increase the crawlability of websites. And these elements are important for businesses in many ways. For example, ranking high on SERPs is linked with greater visibility. Furthermore, statistics show that a majority of search engine users do not go beyond the third page. At the same time, 60% of users usually click on one of the top three results.
Appearing on the first few pages, therefore, leads to more clicks, and this can lead to greater revenue upon conversion. Simply, SEO promotes organic marketing.
It is also worth pointing out that you can use web crawlers to guide data collection initiatives via the internet. At the same time, you can use SEO crawlers to optimize your site’s crawlability.
