The short definition
When a shopper types a keyword on Blinkit, they see a ranked list of products. Share of search measures how much of that list is your brand. Because shoppers look at the top and rarely scroll far, a good measure gives more weight to higher positions and counts the first scroll on its own.
Why the first scroll
On a phone, only the first few results show before the shopper scrolls. That is the first scroll. Most buying decisions happen there. Being tenth for a keyword is close to being absent. So the most useful version of share of search is first-scroll share: of the slots a shopper sees without scrolling, how many are yours?
Organic and sponsored, measured apart
Blinkit search results mix organic listings and sponsored listings marked as ads. Both make you visible, but they are different problems:
- Organic share is earned. It comes from sales history, relevance, availability and listing quality. It stays when you stop spending.
- Sponsored share is rented. It lasts as long as the budget does.
A brand with high total share that is mostly sponsored has a cost problem waiting to happen. A brand with high organic share on a keyword may be paying for ads it doesn't need there. Keep them apart.
Weight by search volume, read by city
Not all keywords are equal. Your brand name gets fewer searches than the category's generic terms, where most shoppers start. Weight each keyword by its search volume when you add them up.
Read it by city, too. Each dark store has its own results, and a national number can hide a city where you have vanished.
Branded vs generic keywords
Many brands hold their own brand keyword and almost nothing on the generic keywords where most searches happen. Share of search makes that gap visible. Defend branded keywords if competitors bid on them; win generic keywords to grow.
How to use it
- Find keywords where you rank just below the first scroll. Small gains there are cheap.
- Find keywords where you hold the first scroll organically and check you aren't paying for ads on top.
- Watch competitors whose sponsored share is rising. They are buying the category.
- When share drops in a city, check availability first. Out-of-stock products drop out of results.
