Ads & analytics
Meta ads, and reports that check their own numbers, for watch, apparel, real-estate and EV brands.
1,603leads for a real-estate developer at ~₹183 ($2) each
693 of 698 leads reached the sales sheet within 30 seconds. Half took 11 seconds or less.
In the sheet within 30 seconds: 693Took longer: 5
Of the 5 that took longer, 2 took a few minutes and the nightly sweep caught the other 3, hours later. One dot is one lead, and all it holds is a date. Names and numbers stay in the client's sheet. From the pipeline's own log, test leads removed. Meta's own count for 23 July to 6 November is 692.

“Your work has genuinely increased productivity at work. Before you, I used to spend entire mornings or even days processing the leads for a batch. Your automations helped me get my time back.”
“These are some awesome reports and website ideas.”
