Comparing Web-Scraped Displayed Sales Counts of Products with and without Halal Labels on Tokopedia

E-commerce marketplaces provide observable sales indicators that can complement survey-based studies of halal-related purchasing behavior. This study compares displayed sales counts for packaged food and beverage products displaying a halal label and products not displaying a halal label on Tokopedia. Data were collected through web scraping using 30 purposively selected product queries, comprising 15 queries in each displayed-label-status group. Web scraping produced 7,234 listings; after preprocessing and the primary 5th–95th percentile trimming procedure, 3,759 listings remained. Listing-level exploratory analysis was used to describe marketplace characteristics, whereas inferential analysis was conducted at the product-query level by summarizing each query using its median displayed sales count. A two-sided Mann–Whitney U test yielded U = 161.0 and p = 0.044, with Cliff’s delta of 0.431. Sensitivity analyses using no percentile trimming and alternative percentile thresholds produced the same direction of difference and inferential decision at α = 0.05, although effect estimates varied. The findings indicate different observed sales patterns between the selected groups but do not establish an independent or causal effect of displayed halal-label status because price and other product and marketplace characteristics were not controlled.
