A Kolkata Tech Blog's Push-Notification Bet Pays Off With 10% Growth

Who built it, and what they built

Abhishek Ghosh runs The Customize Windows, a technology blog based in Kolkata, West Bengal, India, that publishes theory and how-to guides aimed at makers, webmasters, and small business owners. The site has been publishing since October 2010 and operates with a team of four.

The business earns $2,800 per month and also runs an IT consultancy alongside the blog, with reader feedback helping shape where the work goes next.

How they grew

The founder credits a set of deliberate tactics for the year's growth. On Pinterest, the account moved from 20K to 24K followers over one year by publishing more informative pins, using affordable high-quality stock imagery suited to high-resolution mobile screens, and watching what competing sites in the niche were doing on the platform.

A second lever was giving mobile visitors an easy way to subscribe and get notified about new articles, something the site lacked the previous year. Comparing the last 28 days against the same period a year earlier showed close to a 10% lift, which the founder attributes partly to this change retaining traffic.

Content strategy also shifted toward flagship handsets, with in-depth coverage of recent Samsung foldable and Ultra models, including head-to-head comparisons and practical pieces such as what goes wrong when sketching with a stylus on a folding screen.
