Screenshot for Parsero tool review


Entries that should not be crawled by a web spider, are typically placed in a Disallow entry in the robots.txt file. This file is read by a crawl tool and any of the Disallow entries are skipped for indexing. These entries are interesting, as sometimes they reveal a lot of information about the web server. This tool helps to quickly check which entries are accessible.
