Twitterbot/1.0 is a crawler that does not belong to social network Twitter (as is the case with FacebookExternalHit or LinkedInBot). Moreover, the user agent doesn?t provide a domain, making it unknown what the bot does and where it does belong to. A Twitterbot is the name for an automated program that can post on twitter, but, again, it is unknown whether this bot crawls for information in order to tweet it online (probably not).
The Internet of Bots has evaluated Twitterbot against 50 different checkpoints, of which 13 have been confirmed as being positive. These checkpoints evaluate the transparency and occurrence of a bot and don´t necessarily say something about its quality. The BotRank is calculated as [13*2=] 26%. The details of the bot and the BotRank can be seen below. For more information on how the BotRank is made, you can visit the page Botrank.
