What you get from a website design company in Mumbai that has done this for 20 years

• A site built to be found: clean URLs, fast loading, structured data, a sitemap and on-page SEO are part of every build, not an extra.
• A site built to convert: clear messaging, trust signals, enquiry forms, click-to-call and WhatsApp buttons on every page.
• A site you control: an easy admin panel to update text, images, services, projects and blog posts without calling a developer.
• A site that lasts: secure hosting setup, backups, SSL and maintenance plans so your website keeps working long after launch.

How we work

1. Discover: we learn about your business, buyers, competitors and goals, and review your current website and rankings.
2. Plan and design: a sitemap, keyword plan and page designs for your approval before any code is written.
3. Develop and test: responsive development, content entry, speed and SEO checks, and testing on phones, tablets and desktops.
4. Launch and grow: go-live with redirects from your old site, Google Search Console and Analytics set up, then ongoing SEO and marketing if you want it.

Industries we know well

Over two decades we have built and marketed websites for industrial automation and engineering companies, pharmaceutical and medical device manufacturers, leather and garment exporters, travel agencies, safety and security firms, power and UPS suppliers, real estate developers and professional services. Knowing how buyers in these industries search and decide helps us write better pages, choose better keywords and generate better-quality enquiries, whether your customers are in Mumbai, elsewhere in India or overseas.

How much does a website cost?

Website cost depends on the number of pages, the design work, features such as product catalogues, online payments or customer logins, and how much content we write for you. A focused company website costs far less than a large e-commerce store or a custom web application. After a short call we send a fixed quote with a clear scope and timeline, so there are no surprises. Most business websites go live in three to six weeks.
