Approximately 65% of the total ranking is directly or indirectly connected to reviews.
On Naver Shopping, reviews are not "supplementary info" — they are "core inputs to the algorithm."
Correlation between search ranking and review count for the "toner" keyword in Naver Shopping Beauty category. Estimated based on public data.[1][2]
Naver's algorithm assigns higher weight to reviews from the last 30 days.[1]
Even with 5,000 cumulative reviews, if there are 0 reviews in the last 30 days, rankings drop.
Consistent review inflow = the key to maintaining rankings.
Products with 20%+ photo review ratio have 2.1x higher conversion rates.[2]
To appear in Naver's "Products with Great Reviews" filter, a 15%+ photo ratio is required.
10 text reviews < 3 photo reviews (by conversion rate).
Naver Shopping Page 1 entry = 1,000 reviews + consistent inflow over the last 30 days.
For the "toner" keyword, the average review count for Page 1 products (rank 1–40) is 3,200.
Products with fewer than 500 reviews rank below 80th, effectively invisible in search results.
The first milestone is 1,000 reviews; 5,000 reviews puts you in the safe zone.
