What our customers are saying


At A Glance: Web Crawler

Everyone knows there are unimaginable amounts of information available on the Internet — everything from the fascinating and useful to the obscure and pointless. Finding that one little piece of information among the flood would be nearly impossible without search engines. But how do search engines find that information for us? They employ something called a web crawler. While the mental image may be of a computerized spider crawling through the Internet, the reality is that these programs scan the web for the information requested; they’re also known as bots. The crawler checks a page for the word or words it has been instructed to find and compiles the results into an index.

This means web crawlers have a variety of vital uses to a business, as well as to an individual, and when it comes to catching crawlers’ attention in the right way, a business will often opt to hire web crawler specialists on Upwork to do the job. Part of the reason for this is that crawlers can’t always see everything on a website, with dynamic content topping the list of things that can confuse them. Animations, forms, and flash content can also get past crawlers, meaning a website might not show up in search results as it should. Therefore, a freelance web crawler specialist is able to ensure all the information on a site can be seen by the crawlers and therefore added to those all-important search indexes.
