E-commerce sites are full of product content and data that bad bots can scrape. This enables competitors and attackers to steal a site's product information and sensitive data. Not only are these bad bots stealing proprietary data, the activity sucks up the site's bandwidth. This, in turn, slows down the site's performance, which can cause downtime and additional overhead if not blocked.
Content scraping bots often create fake registrations and form fills. These need to often be purged manually, increasing customer support and administrative costs.
Content scraping activity can have a real impact on the site's financials. Scraping can lead to competitor price undercutting, promotional content stealing and unattributed content theft. Not only does this result in lost revenue, it can lead to negative SEO.
