Introducing new ranking rules on FollowFriday.com

Today we are releasing a major update of FollowFriday.com. The aim of the new rules is to maintain the purity of the FollowFriday Ranking and ensure that the ranking is free of manipulation and is a true reflection of those valuable recommendations made.

Now, each #followfriday tweet is worth a base score in the range of 0 to 150 points. This score is computed by an algorithm that semantically analyzes the tweet and measures the recommendation quality.

Each #followfriday recommendation is worth the computed base score divided by the number of users recommended in that tweet. So if you receive a #followfriday recommendation which only mentions you in the tweet, and correctly justifies why I should follow you, then you will get 150 points. If the tweet mentions two users you will each receive 75 points, and so on.

Well done #followfriday recommendations:
Special #FF to @heidicohen, that writes such great tips about Twitter.
#followfriday to @SocialBro, an innovative tool to manage and analyze Twitter communities.

Bad examples of #followfriday:
#followfriday to @followfriday_es because yes!
#FF to @SocialBro, @locafollow, @followfridaycom and @resonancers

Updated rules:
  • Each #followfriday tweet is worth a base score in the range of 0 to 150 points. This score is computed by an algorithm that semantically analyzes the tweet and measures the recommendation quality.
  • Each #followfriday recommendation is worth the computed base score divided by the number of users recommended in that tweet. So if you receive a followfriday recommendation which only mentions you in the tweet, and correctly justifies why I should follow you, then you will get 150 points. If the tweet mentions 2 users you will each receive 75 points, and so on.
  • If you recommend the same person repeatedly during the same week, only the first recommendation will be taken into account.
  • Users that make more than 50 recommendations won't be ranked. Their profiles will still be shown but they will not be ranked.
  • Self recommendations won't be taken into account.
  • Re-tweets won't be taken into account
  • Thank you tweets won't be taken into account
  • If you have a lot of accounts collaborating and recommending each other to promote their rankings then all of them will be banned.
  • Country and language rankings are computed based on our automatic geolocalization algorithms, if you want to be sure to appear in the correct rankings then login and edit your profile.
  • Protected accounts won't be ranked. Their profile will still be shown but they will not be ranked.
All of these rules are applied automatically, but we also have an anti-spam team that continually checks the rankings.

Ranking Rules

Introducing new ranking rules on FollowFriday.com

Today we are releasing a major update of FollowFriday.com. We continue to fight the spam on the #followfriday hashtag, so we are changing the ranking rules to reward those shoutouts which are more spontaneous. We are introducing a new points based algorithm where each followfriday recommendation is worth 50 points divided by the number of users recommended in that tweet. So if you receive a followfriday recommendation which only mentions you in the tweet, then you will get 50 points. If the tweet mentions 2 users you will each receive 25 points, and so on.

Points = 50 / (Number of mentions in the tweet)

As part of this new algorithm we have stopped taking into account retweets and thank you recommendations. In this way we don't value users who abuse these techniques.

We are also introducing a big infrastructure improvement which now allows us to calculate your exact position in the global ranking even if it exceeds 1000. So now our widgets have more sense and reflect your precise position.
