Our Recent Work – Success Stories in Kolkata
We deliver proven results as the Best Website Development and CCTV Installation Company in Kolkata.
Evelyn Computers (Madhyamgram)
- The Scope: A comprehensive IT & security client utilizing our Graphic Design, Signage Board, and CCTV Installation/Maintenance services. Their primary transformation project was Custom E-commerce Website Development.
Our Approach: We transformed this popular local hardware shop in Madhyamgram into a digital powerhouse. We built a responsive, secure, and user-friendly e-commerce platform capable of handling complex hardware inventory. The development focused on speed, mobile optimization, and seamless payment gateway integration.
The Benefit: By transitioning from a physical-only model to a hybrid model, Evelyn Computers expanded their customer base far beyond their neighborhood. They now enjoy 24/7 sales capabilities and automated inventory tracking, significantly increasing their monthly revenue.
Sonama Aya Centre (Airport Area)
The Scope: A long-term partner relying on us for Website Development, Maintenance, and CCTV Installation. However, their critical focus was achieving dominance through Local SEO & Google Ranking.
Our Approach: To capture the competitive market around the Airport area, we implemented a hyper-local SEO strategy. This included optimizing their Google Business Profile, creating keyword-rich content (targeting high-volume terms like “Best Aya Centre in Kolkata”), and building high-quality local citations.
The Benefit: The center moved from Page 3 to the #1 Position on Google Search for their target keywords. This visibility resulted in a massive surge in organic inquiries and phone calls, drastically reducing their need for paid advertisements.
Women’s N Kids Hub (Birati)
The Scope: A retail brand utilizing our E-commerce Website Development and CCTV Services to run their business. Their spotlight project was upgrading their physical presence with Premium Outdoor Branding & ACP Signage.
Our Approach: We knew that for a gift shop in Birati, curb appeal is everything. We designed and installed a high-durability, 3D LED-backlit ACP (Aluminum Composite Panel) signage board. The design was strategic—ensuring the logo lights pop from a distance at night while the board resists weather wear during the day.
The Benefit: The store saw an immediate increase in footfall and walk-in customers. The premium signage established them as a trusted, high-end destination in the locality, instantly distinguishing them from nearby competitors.
Urban Exotica (New Barrackpur)
The Scope: A residential complex utilizing our Website Development and Poster Installation services for community management. Their major mandate was implementing High-Definition Commercial CCTV Installation.
Our Approach: We conducted a security audit to identify blind spots across this New Barrackpur apartment complex. We installed a networked system of IP-based, high-definition night-vision cameras with remote viewing capabilities, ensuring every entry, exit, and common area was covered without cluttering the building’s aesthetics.
The Benefit: The complex achieved 100% blind-spot coverage, drastically improving resident safety. The management committee now monitors the premises remotely via mobile apps, leading to faster incident response times and enhanced property value.
Airway India (Barasat)
The Scope: A specialized aviation training institute in Barasat. While they utilize our general IT support, their critical requirement was dominating the education sector through SEO Services.
Our Approach: Education marketing relies on trust and findability. We executed a student-focused SEO campaign targeting competitive keywords like “Best Air Hostess Training in Barasat” and “Cabin Crew Courses.” We optimized their site structure to ensure prospective students could easily find course details and success stories.
The Benefit: The institute saw a significant rise in student inquiries and organic website traffic. They now rank at the top of local search results, establishing them as the premier choice for aviation training in the North 24 Parganas region.
New Bhojon (Sealdah)
The Scope: A busy catering service provider based in Sealdah. They partnered with us to scale their bookings using Digital Marketing Services, specifically Facebook & Google Ads.
Our Approach: Catering is a highly visual and competitive market. We launched high-conversion ad campaigns targeting users searching for wedding and corporate event planning. We used visually appealing creatives on Facebook to showcase their food quality and targeted intent-based search queries on Google for immediate leads.
The Benefit: The campaign delivered a high Return on Ad Spend (ROAS). New Bhojon experienced a surge in verified leads and confirmed bookings for the wedding season, filling their event calendar months in advance.
Medigocare (Delhi)
The Scope: A medical tourism company based in Delhi. As a national client, they entrusted us with their digital face, focusing entirely on professional Website Design & Development.
Our Approach: Trust is the currency of medical tourism. We designed a clean, compassionate, and informative website that instills confidence in international and domestic patients. The site features easy navigation for treatment options, doctor profiles, and a streamlined inquiry system compliant with healthcare standards.
The Benefit: The new website drastically improved their user engagement and conversion rate. Patients can now easily access vital information, resulting in a higher volume of qualified patient inquiries from across the country and abroad.
Zrurihai (Kolkata)
The Scope: An innovative, app-based multi-household helping service in Kolkata. This was a full-scale startup project requiring our expertise in Software Development, SEO, and Branding.
Our Approach: We acted as their technical backbone. We developed a robust, user-friendly mobile application (Software Development) to connect helpers with households. Simultaneously, we built a cohesive brand identity (Branding) to ensure market recall and implemented an SEO strategy to ensure the app appears when users search for “maid services” or “home help” in Kolkata.
The Benefit: Zrurihai successfully launched with a fully functional platform that handles real-time bookings seamlessly. The combined branding and SEO efforts created immediate market buzz, driving initial app downloads and user registrations rapidly.
