Choosing a product lineup — sound familiar?
TURF finds the combination that reaches the most people — with the fewest items.
01 · REACH CURVE
How many customers can your current line-up reach?
See where reach growth starts to slow down.
TURF — Total Unduplicated Reach and Frequency — calculates how many unique people are reached by a set of items. The reach curve shows cumulative reach as items are added, and flags the point of diminishing returns where each additional item contributes little new reach.
Reach climbs fast then flattens — adding a 5th item gains only +4pp.
02 · BEST PORTFOLIO
The combination that reaches the most customers.
See the best combination for every portfolio size.
Skari searches all combinations and returns the highest-reach set for each size — the best single item, the best pair, the best trio, and so on. Instead of guessing which three flavors, features, or messages to ship, you get the exact combination that maximizes unique reach.
03 · MARGINAL REACH
The actual new customers each item adds.
Count only the newly reached customers.
A popular item can be redundant if everyone who likes it already likes something else in your set. Marginal reach shows the net new customers each item brings to the portfolio — so you keep items that expand your audience and drop the ones that only duplicate existing reach.
New people reached by adding each item to the portfolio.
04 · DUPLICATION
Check overlap between products.
Find items that share the same customer base.
Two items that appeal to the exact same respondents cannibalize each other — carrying both costs more without adding reach. The duplication view shows pairwise overlap so you can identify near-substitutes and choose the one that pairs best with the rest of your portfolio.
Share of respondents who like both items — high overlap means cannibalization.
Mango × Mint overlap (24%) — keeping both adds little net reach.
