What is a bot?

Indexing websites is the basis for how search engines like Google or Bing work. Only by using web crawlers, which analyze and index URLs, is it at all possible to sort and present search results. These bots independently scour the internet for relevant content to list on search services.

Particularly in e-commerce, companies increasingly rely on chatbots for customer support. The automated helpers provide answers to the most relevant questions and support customers when shopping or troubleshooting. For more complex topics, the customer is usually referred to conventional customer support. This enables companies to lower the workload of their own service teams and provide cost-effective 24/7 support for their customers.

Social bots, as the name implies, are mainly used in social networks such as Facebook or Twitter. Here, the tools perform a variety of tasks:

• Publishing content for a page or a user.

• Automatically liking and commenting on Facebook posts or retweeting and commenting on tweets.

• Interactive user communication as a chatbot. However, this application is not allowed in the terms and conditions of most social networks.

Bots are also used to trade digital currency. The prices of Bitcoin and other cryptocurrencies are extremely volatile, so it makes sense to continuously monitor your own investment. Since no one can do this from an economic standpoint, trading bots handle this task.

We also encounter bots in computer games, mostly as NPCs (non-player characters). They are computer-controlled players or opponents in PC games. In online role-playing games, there are other types of game bots that players employ to perform monotonous tasks, such as collecting resources or experience points. However, most games do not allow the use of such bots and ban players who use them.

Similar to chat bots, email bots manage conversations with customers and prospects. Email bots can be integrated into existing email automation platforms and take over part of email communication. These mailing tools are particularly suitable for simple support or contact requests.

Cybercriminals sometimes use bots to send spam e-mail. They use email harvesters that automatically scan websites for publicly accessible addresses. The fraudsters then sell these mass-aggregated addresses for a profit on the darknet or use them themselves as targets for spam campaigns. The actual sending is also usually done using bots or botnets.
