Chatbots have revolutionized the way customers interact with businesses. According to HubSpot, “47% of consumers are open to buying items through a chatbot”. Thus, majority of organisations have joined the race of augmenting or building these virtual agents on their websites. 


The road towards the widespread adoption of chatbots is not all picture perfect, but comes with many roadblocks and pitfalls for you to be prepared of. There are numerous chatbot development tools and practices to take into account, however firms tend to overlook few critical aspects during chatbot development.

Here are 4 biggest challenges that companies face during chatbot development and ways to effectively tackle them.

1. Context in Chatbots

The key to the evolution of any chatbot is it’s integration with context and meaningful responses, as conversation without any context would be vague. It becomes challenging for companies to build, develop and maintain the memory of bots that offers personalized responses.

That’s when AI technologies like Machine Learning or NLP- Natural Language Processing come into the picture and overcome the challenge of understanding the depth of conversation; up-to an extent. NLP understands the databases and data sets when bots are structured, in predefined sequential order and then converts it into a language that users understand.

However, humans don’t interact in a defined order, as a result intelligent slot filling, which stores the preferences of the regular users is the alternative to maintain the memory of a bot effectively. This insures that your virtual agents are not interacting in the same old predefined order but in a more personalized fashion.

2. Limited User Attention 

Users have limited time span for their queries and expect lightning-fast replies. It’s quite challenging for firms to develop chatbots, that holds user’s attention till the end.

Conversational UI, here plays an important role in exhibiting human like conversations and better customer experiences. It initiates interactions to be more social than being technological in nature. The conversations as a result, should be natural, creative and emotional in order for your chatbot to be successful. In some cases, however a machine wouldn’t always render the same empathy that a human could and this is when a human replacement should take care of the users request.

3. Chatbot Testing

Chatbot testing is another main issue where most of the complexity lies. Chatbots are continuously evolving due to its upgradation in natural language models. Thus, it becomes vital to test and run chatbot to check it’s accuracy. Testing a chatbot will depend on what type of method you want to experiment.


  • First method involves automated testing of chatbots. There are many automation testing platforms like Zypnos, TestyourBot, Bot Testing, Dimon etc. These platforms allow detailed reports of the results and coding of test scripts, which could be run for all the test cases.

  • The other method involves  testing of conversational logic i.e. manual testing executed by a closed group of testers. They act as users and check the bot for all the unexpected slots possible. This method can be time consuming and partially accurate. However, it has its own benefits that outrage automation, by checking the logic against human conversations.

The best alternative is to combine both the methods to insure that your users are being served better.

4. Viability of Data

There is no point of having lots of data, intelligent slot filling or technologically advanced chatbot- if it actually doesn't deliver the USP of your organisation. It is vital for a chatbot to not only be enriched with meaningful data, but also to be equipped to deliver the brand identity to your target audience. In order to check the viability of your virtual agents you should consider asking yourself the following:

  • Are your virtual agents delivering to the right audience?
  • Does it offer business goals uniquely?
  • How is it different from other chatbots?

It may definitely seem to be a great idea to implement chatbot in your digital strategy, but creating a one that meets the expectations of your organisation and users, is a big challenge. An effective and well planned strategy is important for you to consider before presenting the chatbot to your audience. If done well, chatbots can become the contact point for your business and can increase the overall productivity by meeting the customer’s on-demand expectations.
