Internet bots are software applications that are used on the Internet for both legitimate and malicious purposes. Because of the increasing number of applications becoming available online, there are many different types of Internet bots that assist with running applications such as instant messenger and online gaming applications as well as analysis and gathering of data files.
Bots and Botnets are commonly associated with cybercriminals stealing data, identities, credit card numbers and worse. But bots can also serve good purposes. Separating good bots from bad can also make a big difference in how you protect your company’s website and ensure that that your site gets the Internet traffic it deserves.
The Most Good Bots are essentially crawlers sent out from the world’s biggest web sites to index content for their search engines and social media platforms. You WANT those bots to visit you. They bring you more business! Shutting them down as part of strategy to block bad bots is a losing strategy.
Googlebot – Googlebot is Google’s web crawling bot (sometimes also called a “spider”). Googlebot uses an algorithmic process: computer programs determine which sites to crawl, how often, and how many pages to fetch from each site. Googlebot’s crawl process begins with a list of webpage URLs, generated from previous crawl processes and augmented with Sitemap data provided by webmasters. As Googlebot visits each of these websites it detects links (SRC and HREF) on each page and adds them to its list of pages to crawl. New sites, changes to existing sites, and dead links are noted and used to update the Google index.
