How to manage good bots? Difference between good bots and bad bots

A bot, short for “robot,” is a type of software program that can automatically perform tasks quickly and efficiently. These tasks can range from simple things like getting weather updates and news alerts to more complex ones like data entry and analysis. While bots can be beneficial in our daily lives, they are also associated with malicious activities we’re all too familiar with, such as DDoS attacks and credit card fraud.

In this post, we’ll dive deep into the topic and explore the difference between good bots and bad bots. You’ll learn about bot management, including best practices and available tools to identify and implement them. By the time you finish reading, you’ll have a good grasp on how to properly manage bots on your website or application—and how to keep any bad bots from getting through the door.

What is a good bot?

Good bots, also known as helpful or valuable bots, are software programs that are designed to perform specific tasks that benefit the user or the organization. They are built to improve the user experience on the internet.

For instance, good bots crawl through websites, examining the content to ensure it is safe. Search engines like Google use these crawlers to check web pages and improve search results. Also, good bots can be found performing various tasks such as gathering and organizing information, conducting analytics, sending reminders, and providing basic customer service.

Now that you’re familiar with what a good bot is, let’s take a look at some specific instances of their use “in the wild.”

The following are examples of good bots:

• Search engine crawlers. Googlebots and Bingbots are web crawlers that help the search engines Google and Bing, respectively, index and rank web pages. These types of bots comb through the entire internet to find the best content that can enhance search engine results.
• Site monitoring bot. This type of bot is used to continuously monitor a website or web application for availability, performance, and functionality. It helps detect (and alert us about) issues that could affect the user experience, such as slow page load times, broken links, or server errors. Some examples of these are Uptime Robot, StatusCake, and Pingdom.
• Social media crawlers. Social networking sites use bots like these to make better content recommendations as well as battle spam and fake accounts, all with the intent of presenting an optimal and safe online environment for the site’s users. Examples of such bots are the Facebook crawler and Pinterest crawler.
• Chatbot. Facebook’s Messenger and Google Assistant are bots that can automate repetitive tasks like responding to chat messages. They mimic human conversation by replying to specific prompts with predetermined answers. Another example, OpenAI’s ChatGPT, serves as a highly advanced chatbot, utilizing AI/ML technology to simulate human conversation and provide automated responses to individual queries. This can save time and resources for organizations of all sizes, whether it’s a big company, a small business, or even an individual user.
• Voice bot. Also referred to as voice-enabled chatbots, these run on AI-powered software that can accept voice commands and respond with voice output. They provide users with a more efficient means of communication when compared to text-based chatbots. Well-known examples of voice bots include Apple’s Siri, Amazon’s Alexa, and the above-mentioned Google Assistant.
• Aggregator bot. Like the name implies, this bot vacuums up web data, gathering information on a wide range of topics—weather updates, stock prices, news headlines, etc. It brings all of this information together and presents it in one convenient location. Google News and Feedly are examples of aggregator bots in action.

There are many other fields where good bots are in use—in fintech (making split-second decisions in the stock market), in video games (as automated players), in healthcare (assisting with research tasks and test analysis), and numerous other applications.

We’ve covered the basics of what good bots are and how they are employed for our benefit—now it’s time to start talking about the bad ones.

What is a bad bot?

Bad bots are a type of software application that is created with the intention of causing harm. They are programmed to perform automated tasks such as scraping website content, spamming, hacking, and committing fraud. Unlike good bots that assist users, bad bots have the opposite effect: spreading disinformation, crashing websites, infiltrating social media sites, using fake accounts to spam malicious content, etc.

Imagine the impact on specific individuals or organizations once bad bots target them. The result can be financial loss, reputational damage, even legal issues if sensitive information is stolen or shared—or all of the above. It can also lead to identity theft or other types of cybercrime. The consequences can be severe, and individuals and industries must take necessary precautions to protect themselves from bad bots.

Read on to familiarize yourself with instances of bad bots and how they operate.

Examples of bad bots are the following:

• Web content scraper. Initially, there are some positives in using web content scrapers (for ethical purposes), but mostly it’s being used with bad intentions. The intent is to crawl websites and collect confidential data, such as personal details and financial information, which can be used for identity theft, financial fraud and/or data breaches. For instance, a cybercriminal may target an e-commerce website with a scraper designed to extract sensitive information, resulting in financial losses for both individuals and businesses.
• Spammer bot. Bots utilized to send spam messages or post spam comments on websites and social media platforms. As per SpamLaws, spam is responsible for 14.5 billion messages globally per day, representing 45% of all emails generated—and the bots are responsible for a significant part of it.
• DDoS bot. These bots are used to launch DDoS attacks against websites by overwhelming them with traffic, making those sites unavailable to legitimate users. Cybercriminals are taking advantage of these bad bots, resulting in DDoS attacks that have become more complex than ever before.
• Click fraud bot. A bot created specifically to artificially inflate advertising platform revenue by clicking on links or ads. Bad bots generate these fake page views and clicks, distorting the real metrics of ad performance, which in turn defrauds advertisers. According to Statista, digital advertising fraud costs are predicted to rise from $35 billion to $100 billion between 2018 and 2023, potentially causing significant losses for online publishers.

• Account takeover bot. This type of bad bot attempts to gain unauthorized access to a user’s online account by automating the process of guessing or cracking login credentials. Once access is gained, the bot can carry out malicious activities, such as credit card fraud or stealing sensitive information.

Take note that malicious and harmful bots have become more advanced in recent years because of cybercriminals, making them more challenging to identify and block—the bots have evolved from basic crawlers to more sophisticated programs that mimic human behavior, using advanced techniques to avoid detection.

Let’s now proceed to highlighting some telltale signs—the indicators—that will help inform you if a particular bot is good or evil.

How do you best identify the good bots from bad bots?

We’ve discussed various ways in which bots are utilized today. The difference lies in the intention of the person who created the bot—it can be either useful or harmful. From the perspective of a business owner or a regular user, how can you distinguish between good and bad bots? Even for someone who is new to the subject, there are ways to differentiate between the two.

What is bot management and how does it work?

Bot management is necessary for identifying, monitoring, and tracking the behavior of bots on a website or network. It aims to manage good bots, which are beneficial to the website or network, while protecting against bad bots, which can cause harm. The goal is to take advantage of the good bots and eliminate the negative impact of the malicious ones.

For a business/website owner, bot management is of utmost importance, as it plays a vital role in protecting your online assets and maintaining the integrity of your website. Here are a few key reasons why bot management should be on your radar:

1. Protects against spam and fraud. Bot management can help identify and prevent spam and fraudulent activities on your website. This not only protects your business and its reputation, but it also helps ensure the safety of your customers.
2. Maintains website performance. Bots in general can consume a significant amount of your website’s resources, slowing down the performance and affecting the user experience. Properly managing bots helps to regulate and control the bot traffic, reduce the load on your servers and maintain the website performance.
3. Ensures fair competition. Managing bots also helps prevent the use of bad bots from unethical scraping of a website’s content, ensuring a fair and level playing field for all businesses. For instance, web scraping can be used by your competitor to research and analyze your website—for example, to find out what your best product offerings, features, categories, and bundle deals are. Competitors can also use illegal scraping of SEO strategies, social media presence, and consumer feedback through comments, posts and reviews.
4. Protects against legal liabilities. Managing bots protects you against legal liabilities and strengthens user privacy. A bot management system could help an organization comply with, for example, the European Union’s General Data Protection Regulation (GDPR). The protocol requires companies to protect the personal data of EU citizens, making sure that the data is processed in a transparent and secure manner.
5. Compliance with regulations. Certain industries and sectors are subject to regulations that require them to protect user data and prevent malicious activity. Managing bots can help organizations and website owners to comply with these regulations and avoid costly fines.
6. Protects online advertising revenue. Malicious bots can compromise online advertising systems, leading to lost revenue for publishers and advertisers. You can prevent this by blocking harmful bots from accessing advertising networks.
7. Preserves the integrity of online data and analytics. Bot management helps to prevent bots from skewing website analytics and distorting the data that businesses rely on to make informed decisions.

In bot management, the process typically involves several technical components. Let’s take a look at how this system works and see some examples.

These are a few examples of some of the technical components in bot management. Apart from the ones mentioned above, there are some specific components and tools used depending on the unique needs and requirements of your website and application.
