Nicecrawler

Nicecrawler is a web scraping bot that systematically collects data from websites. It operates from the domain nicecrawler.com, though public information about its operator is limited. It is classified as a web scraper, visiting websites to extract content. The bot identifies itself in server logs with a distinctive user-agent string: Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Nicecrawler/1.1; +http://www.nicecrawler.com/). It operates from a consistent set of US-based IP addresses, which suggests a professional operation designed for systematic data collection.

Nicecrawler is likely visiting your website to collect and index content for its data services. While its specific targets are not public, its behavior is similar to other commercial scrapers that gather information for market research, price monitoring, or content aggregation. The frequency of its visits depends on how often your content changes and its relevance to the service's data collection goals. Although the crawling is likely not explicitly authorized by you, the bot operates like many commercial scrapers that rely on robots.txt compliance as a form of implicit consent.

Nicecrawler appears to be a commercial web scraping service that collects data from websites for business intelligence or market analysis. The information it gathers is likely processed and sold to clients. For website owners, the bot's activity could be a concern if you do not want your content or pricing data automatically extracted. Unlike major search engine crawlers that provide clear value through search visibility, the benefit of being crawled by Nicecrawler depends on how the service uses and distributes the collected data.

To prevent Nicecrawler from scraping your website, you can add a disallow rule for it in your robots.txt file. This is the standard method for managing access for web crawlers that identify themselves.

Add the following lines to your robots.txt file to block Nicecrawler:

User-agent: Nicecrawler
Disallow: /
