To get this information, in general, people use search engines or search engines that can make it easier to search for information. Some search engines available on the internet utilize web crawlers to obtain the information needed by users. This research developed a web crawler application to retrieve information about prices from two comparison sites, namely the elevenia site and the mataharimall site. The data obtained from the crawling process will be stored in a database which can then be used by users to see price comparisons of the products they are looking for, then users can also see the details of the products they are looking for. This system was developed using the waterfall method and displaying it in a Cross Selling format for the product it was looking for. This research has resulted in crawler applications and systems using cross selling.</p> Adelia rudangta Wirda fitriani Herdianto Copyright (c) 2024 International Journal Of Computer Sciences and Mathematics Engineering https://creativecommons.org/licenses/by-sa/4.0 2024-10-01 2024-10-01 3 2 1 9 10.61306/ijecom.v3i2.88
