Paid user acquisition is a curse. Later stage consumer startups that depend on it are the walking dead.

• After launch, ROI declines consistently across every advertising channel
• Early metrics are misleading because traffic is front-loaded due to the way ad algos work

Digital ad metrics have decayed every year since the industry was created.
• CPMs on major ad networks are now increasing at ~40%/yr.
• In 1997, CTR on HotWired was 78%. In 2019, Facebook’s average CTR is about 0.9%.
(H/t @andrewchen)
Facebook/Google algorithms are so good at targeting people that paid acquisition traffic tends to be highly front-loaded.

Founders and investors are often shocked when numbers rapidly decay — because the ad population has been saturated.
So, what’s the answer for these startups? I think a few things:
1. Optimize ad spend as the userbase saturates
2. Build a distribution moat to re-target customers later
3. Focus the core business on things that spread organically
4. Explore emerging advertising channels quickly

A THREAD ON @SarangSood

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.
