Kolkata is the largest city in the West Bengal region in India and is considered the most competitive one in the IT sector in Bangladesh. The main reason - it’s physically closer than any other city. 

The region includes more than 900 IT companies with 145,000 employees, and 70% of them can be found in the city of Kolkata, which confirms again the strategic importance of the city in the country and the region’s IT industry. Kolkata is called the IT hub of East India, and has plenty of tech parks, including Bengal Eco Intelligent Park, Millennium City IT Park, Image Tech Park, and many more. 

Since early 2010, Kolkata has managed to grow fast and attract huge tech players such as IBM, TCS, PwC, British Telecom, and Ericsson, which consequently invested and developed the IT infrastructure, hiring most of the youth workers who are nowadays enrolled in the system. 

The dominant services in the IT industry in Kolkata include software development, product development and consulting, big data analytics, and system integration, but also digitalization of other services, such as healthcare, architecture, and banking systems, which enjoy a market demand. 

From hardware manufacturers, SME’s like Sonodyne, Videocon, Vikram Solar, Websol Energy, are among the top players in the tech industry as well. 

The region also has 36 IT parks and 14 Business parks, created to stimulate the development of the entire industry and boost the regional economy and competitiveness. And on top of everything, the Kalyani Institute is the main core of future tech workers. 

However, Kolkata remains one of the least paid cities in the IT industry, with a yearly average estimated at $4,386 USD. Yet, this is one of the reasons why big companies invest in this place, and also why IT products and services developed by Kolkata-based IT companies are cheaper than other tech hubs in India. 

In case you are searching for an IT company from Kolkata to work with, on TechBehemoths, you can find the most active ones that perform above-average.

Where do tech businesses advertise?

TechBehemoths conducted a study in the past, where they asked tech companies what digital marketing channels they use the most. SEO/AEO, email marketing, content marketing, social media and PPC were the most popular choices.

An interesting stat revealed that only 21% of survey respondents chose video marketing as their preferred channel. Out of those, only 5.8% of respondents said that their video marketing activity is high (based on a 1-5 scale, where 1 is low and 5 is high).

This can mean a missed opportunity for businesses, as video has become a major media format used on most popular search engines and social media networks.

Getting help from a video production company can significantly contribute to the success of your marketing activity.

Another graph showed that around 30% of tech firms don’t use PPC (pay per click) advertising, which can also mean a missed opportunity.

Getting organic traffic from Google, Bing and other search engines is getting so much harder these days, as AI summaries and AI chatbots make users less likely to click on organic links => company websites don’t get visits.

This is where digital marketing agencies can help you with Google Ads, Bing ads and pay per click services.And finally, only about 3% of respondents said that influencer marketing is a part of their marketing activity and the vast majority of them (around 60%) don’t focus on influencer marketing at all.
 

In the era of AI, personal/real experiences and recommendations matter more than before. Hence, influencer advertising can be a productive marketing channel. Who would you trust more? A human with real feedback or a synthesized AI summary? The answer is obvious.

What digital marketing strategies work in 2026?

Digital marketing in 2026 is no longer optional, it’s essential if not vital. From AI-powered search to short-form video and personalized email campaigns, businesses must adapt to evolving platforms and consumer behavior to stay competitive.

Businesses that ignore investing in a strong online presence - risk losing digital visibility, trust, and competitive advantage.

Here are the most effective types of digital marketing for this year:

1. SEM (Search Engine Marketing)

Search Engine Marketing (SEM) represents a type of digital marketing meant to increase the visibility of a website on search engines. Ultimately, the goal is to try to get as much organic or paid traffic as possible.

SEM is mainly based on 2 parts:

• SEO/AEO/GEO - search or answer or generative engine optimization

• Paid advertising and PPC (pay per click)

As Google dominates the search engine market, it’s vital to be present there and target relevant audiences.

2. Content marketing

Content marketing is based on the creation and distribution of relevant and useful content that attracts the attention of visitors/consumers.

There can be multiple types of content, here is a visual illustration:

3. Social media marketing (SMM)

Almost everyone uses a kind of social media platform. Creating brand awareness on social media can be the primary focus for a business, along with ecommerce opportunities, as there’s a clear trend of people using social platforms for shopping.

4. Email marketing

Email marketing includes sending promotional emails to potential customers. There are different ways to achieve that:

5. Influencer marketing

This might be one of the most overlooked marketing channels and it basically means partnering with an online influencer to market one of your products or services.

In this way, you can get access to their audience of hundreds,thousands or even millions of followers, who trust their influencers.

6. Video marketing

Video marketing might be the future of digital marketing, mainly because of the time people spend on video hosting and streaming platforms like Youtube, TikTok and others. Hence, it makes sense for small and large businesses to invest in it.

According to Renderforrest, video marketing help businesses increase:

• Brand awareness by 70%

• Traffic by 51%

• Sales by 34%

7. VR (Virtual Reality) Marketing

This is an emerging one. VR software takes users in an interactive virtual three-dimensional environment usually using headsets with special lenses (like Meta Quest VR) - to simulate a real-life experience.

While VR marketing might be more expensive, more and more brands use VR for product promotion and virtual storytelling.
