    Let us comprehensively discuss how business chatbots are strengthening their place in the digital marketing strategy.

    What is a chatbot? 

    A chatbot can be defined as an AI based computer program that simulates human conversations. They are also known as digital assistants that understand human capabilities. Bots interpret the user intent, process their requests, and give prompt relevant answers. 



    Bots can communicate through voice as well as text and can be deployed across websites, applications, and messaging channels such as Facebook Messenger, Twitter, or WhatsApp. Together with understanding chatbots, you should also know what is AI and how it makes chatbots even more powerful. 

    Chatbot technology – How do they work? 

    Chatbots work by analyzing and identifying the intent of the user’s request to extract relevant entities, which is the most important task of a chatbot. Once the analysis is done appropriate response is delivered to the user. 


    how chatbot works

    Chatbots work by adopting three classification methods. 

    Pattern matching

    Bots utilize pattern matches to group the text and it produces an appropriate response from the clients. Artificial Intelligence Markup Language (AIML) is a standard structured model of these patterns. A bot is able to get the right answer in the related pattern. The bots react to anything relating to the correlated patterns.

    Natural language understanding (NLU)

    Natural language understanding (NLU) is the ability of the chatbot to understand a human. It is the process of converting text into structured data for a machine to understand. NLU follows three specific concepts. They are: entities, context, and expectations

    Natural language processing (NLP)

    Natural Language Processing (NLP) bots  are designed to convert the text or speech inputs of the user into structured data. The data is further used to choose a relevant answer. NLP includes important steps such as tokenization, chatbot sentiment analysis, entity recognition, and dependency parsing. 

    Types of chatbots 

    Chatbots process data to deliver quick responses to all kinds of users’ requests with pre-defined rules and AI-based chatbots. There are two types of chatbots. 


    Rule-based chatbots

    Rule-based chatbots also referred to as decision-tree bots, use a series of defined rules. These rules are the basis for the types of problems the chatbot is familiar with and can deliver solutions for. 

    Key attributes or rule-based chatbots:

    • These bots follow predetermined rules. So it becomes easy to use the bot for simpler scenarios.
    • Interactions with rule-based chatbots are highly structured and are most applicable to customer support functions.
    • Rule-based bots are ideally suitable for answering common queries such as an inquiry about business hours, delivery status, or tracking details.

    Conversational AI chatbots

    Many of us are confused over the differences between a chatbot vs conversational AI. Well, conversational chatbots combine the power of machine learning and NLP to understand the context and intent of a question before formulating a response. They are driven by chatbot scripts and generate their own answers to more complicated questions using natural-language responses. The more you use and train these bots, the more they learn and the better they operate with the user.

    The conversational communication skills of the chatbot technology empower them to deliver what customers are looking for. 

    Key attributes of AI-enabled chatbots:

    • Conversational bots can understand the context and intent of complex conversations and try to provide more relevant answers.
    • AI bots apply predictive intelligence and sentiment analysis to understand customer emotions closely.
    • Machine learning bots learn from user behavior and provide more personalized conversations.

    Why are chatbots important for your business? 

    80% of marketers plan to start using a chatbot in some way or another. It is a significant reason why brands are investing in improving the customer experience. 

    AI-based chatbots boost operational efficiency and bring cost savings to businesses while offering convenience for customers. Businesses can automate FAQs and reduce the need for human interaction. For customer service tasks, rather than debating the merit of chatbot vs human, it’s important to leverage both and achieve an improved experience for customers.

They can be used with any platform and that’s why you find a chatbot for Android, Facebook, Viber, etc. Here are the six main stages that will help you to create your first chatbot to deliver conversational support to your customers.
