We often seen that some unidentified bots relentlessly use bandwidth of website that cause the loading speed of website become slow and affects the ranking position on search engines like Google, Yahoo, and Bing etc. Bad bots, scrapers and malwares are unwanted visitors to site and harmful to server bandwidth. Bad bots as they are often called refers to programs which visit your web site, either to source content, look for security holes or to scan for email addresses. This is often how your email address ends up on ‘Spam’ databases, because they have set a ‘bot’ to scan the Internet and collect email addresses. These programs and ‘bots’ often ignore the rules set out in ‘robot.txt’ files.
