What are some very advanced growth hacks?

• separate landing pages based on messaging on the ad
• reviewing lower funnel events for watch keyword set instead of just landing page hits/installs
• trying out more channels, stopping channels at a certain spend limit which is optimal
• writing good copy on the ads (under-rated hack)
• testimonial-led marketing- works really well for a low-trust market like India

There is no silver bullet. Just need to keep experimenting and balance creativity with best practices

Usually folks only look at cost per landing or install. Ideally look at lower funnel events (activation, retention, purchase) segmented by channel and cost. This gives a better input to optimise the right channels for ROI based on your biz goals.

Eg - certain Instagram campaigns may give 10 rs install cost but d30 retention is only 5 % Another channel may give 20rs install cost but d30 is 15% - hence better roi if your goal is to get d30 retained users
