/ 01 Website design company in Kolkata
A website shouldbring you work.
A Kolkata company's website has one job: help the right buyer find you on Google, trust what they see and send an enquiry. PromotEdge plans, designs and builds websites for Kolkata exporters, manufacturers, institutes and service firms to do exactly that.
Here is what we usually see: a site made once and left alone. It crawls on a phone, the product list is three years old, and the contact form mails an inbox nobody opens. We plan every page around the next step a visitor should take.
Speed, the phone layout and the basics Google needs are done before launch, and you own the domain, hosting and code. After launch, SEO and conversion optimisation keep the numbers moving. A new site works best inside one plan: see how a Kolkata digital marketing agency plans it. The national service is on our website design and development page.
/ 02 Website design and development in Kolkata
Who in Kolkata needs a website.
Kolkata buyers sit in different lanes. Burrabazar serves retailers across West Bengal and neighbouring states, and Outlook names its sub-markets, such as Mehta Building for medicines, Bagri Market for stationery and plastics and Ezra Street for electrical goods. Wholesalers there need a catalogue with a WhatsApp button and the sub-market name in the address. A state portal puts about 95% of West Bengal's foundry units in Howrah, so foundries need casting pages with drawings. Makers who show at the ILPA leather fair or the Bengal International Jewellery Show need one page to send stall visitors to.

/ 04 Websites for Kolkata businesses
Who a Kolkata website has to convince.
A Kolkata company's website rarely talks only to Kolkata. The visitor may be an importer abroad, a dealer in another state or an IT buyer in another time zone.
Exporters are judged before they are called. Gems and jewellery made up 58.8% of Kolkata district's exports in 2024-25, ahead of iron and steel at 17.5% and textiles at 11.7%. An importer weighing two suppliers opens both sites first. Yours needs specifications, certificates, real factory photos and a quote form that loads fast from abroad.
Specialist buyers search for exact terms. J Thomas, headquartered in Kolkata, calls itself the world's largest and oldest tea auctioneer. West Bengal has 89 of India's 120 composite jute mills (December 2025). Buyers type a tea grade or a jute product, so one clear page per product beats a showy homepage. Selling tea or running a hotel in North Bengal? See how we plan website design for Siliguri.
Tech firms sell to clients far away. The Bengal Chamber estimates West Bengal's IT exports grew from about ₹8,335 crore in 2010-11 to over ₹40,000 crore by 2025. Their site wins clients and hires people: case studies with numbers and a careers page that works on a phone.
Bengali ads need Bengali landing pages. Bengali was the mother tongue of 86.22% of West Bengal in the 2011 Census. A Bengali ad that opens an English page loses people at the moment they were interested. A Bengali version of key pages fixes that.

What a Kolkata visitor checks before they call
Census 2011 gives Kolkata district about 61% Bengali, 23% Hindi and 13% Urdu speakers, as a district data site reports it. So a visitor may read any of three scripts. Hindi readers see Sanmarg and Prabhat Khabar. Bengali readers see Anandabazar Patrika, Sangbad Pratidin or Aajkaal. All are on the ABC list. Spell your name in each script as in your advert. Poila Boishakh, the Bengali New Year, fell on 15 April 2026, when traders open new account books in the Haal Khata custom. PTI said in 2022 that the run-up brings one third of shopkeepers' yearly sales. Put your Haal Khata offer and shop hours on the site a fortnight before.
How we deliver it, and why
How your business model changes the plan
An exporter leads with specifications, certificates and a quote form. A cluster maker selling to wholesalers needs a catalogue and WhatsApp. A school or institute needs course pages and an admissions enquiry form. A brand selling direct needs a store with payments and delivery rules.
- Write the page list and the copy before design. Layouts built around real words do not break when the copy arrives. A page plan you sign.
- Give every product its own clear page. Specialist buyers search exact terms, and each term needs a page. Product pages in the buyer's words.
- Test on a low-cost Android phone. Many visitors browse on mobile data, even where home broadband is fast. A phone test report.
- Map every old address before launch. The Google visits you already earn should survive a redesign. Redirects live on launch day.

IT hubs and business districts
Per Wikipedia, New Town is Kolkata's second IT hub after Salt Lake, and its Bengal Silicon Valley has drawn 41 major companies; data centres by Jio, NTT, Airtel, STT and TCS are running or under way. Tech buyers compare vendor sites side by side, so case studies and speed count. BBD Bagh holds the Calcutta High Court, the RBI's eastern office and the port's head office, Burrabazar has wholesale sub-markets, and Howrah and Dankuni are used for warehousing. We visit your office, warehouse or factory floor and photograph the real thing.

AI in website design: today and next
Today: Google's AI answers
Google says no special markup or file is needed to appear in AI Overviews or AI Mode, only a page that is indexed and eligible to show with a snippet. TechCrunch reported on 8 October 2025 that AI Mode added seven Indian languages, including Bengali. So a site's basics (clear text, fast pages, a Bengali version where buyers use it) matter more than any trick.

Next
Our view: first drafts of pages and screens will keep getting quicker. What will not change is the page plan, your real photos and a test on a real phone.

Common questions.
-
Cost follows the number of pages, who writes the copy, ecommerce, languages and links to your other systems. We don't publish a price list; we quote against a written page list. Ask every bidder for the page list in writing and compare the same scope.
-
Choose the company that shows what you will own and how the site will be judged. Ask who owns the domain, code and content, who writes the copy, how many change rounds are included, how fast the site loads on a phone, and who looks after it.
-
Yes. Websites are planned and managed from our office at Ambuja Neotia Eco Centre, Sector V, so you can sit with the designers for reviews. Our in-house team of 65+ people builds the work, with industry consultants and partner agencies where a job needs them.
-
Yes. Our language partners write or translate the Bengali and Hindi copy, and our team checks every page before it goes live. Each language gets its own pages and web addresses, tagged so Google shows the right version to each searcher.
-
It can, if old pages just vanish. We list every old URL, map it to a new page, set up 301 redirects (permanent forwards that pass on your ranking), and watch Search Console for errors after launch. Most drops come from missed redirects, so we test them before go-live.
-
Get it ready before opening day. ETV Bharat reported a record 32 lakh visitors at the 49th fair, held 22 January to 3 February 2026 at Boimela Prangan in Salt Lake. Add a new-titles page, your stall number and an order form. Ask the organiser, the Publishers and Booksellers Guild, for the next dates.
-
A company website usually takes 4 to 6 weeks. A store or a very large site takes longer, and the quote confirms the timeline. Slow replies on copy and photos are the usual cause of delay, so send them early.
-
You do. The domain, hosting account, code and content are in your company's name, so you keep everything if you ever move on from us. We hand over logins and editable files at launch, and list every account in writing so nothing stays with us by accident.
