When developing a monitoring with the intention of keeping a relationship on social media, it is very important to understand the limitations of this operation in order to avoid being surprised with restrictions existing in each of the networks.
Three recurrent limitations should always be remembered for this process:
• Number of daily interactions allowed for each network
• Posting permissions
• Situations in which the results are not captured
Daily Interactions:
Updatings (tweets and retweets): 1,000 per day – the daily limit is divided into 30-minute intervals, that is, it is possible to post an average of approximately 21 messages every 30 minutes; Direct messages (DMs): 250 per day.
Facebook limitations regarding the number of postings/time are not clear. However, they do exist. Most of them prevents users from performing many similar activities in sequence, aiming at preventing spams or automated behavior.
Some limitations documented:
Maximum of 5000 connections (friends and like): http://www.facebook.com/help/?faq=12276
Maximum of messages sent: http://www.facebook.com/help/?faq=219758951385962
Posting permissions:
Although you can mention any user on a tweet, you cannot send a direct message to any user. Users can only send direct messages to their follower users.
Privacy on Facebook is a little bit more restrictive, and it can change depending on the situation, once a user can change almost all the settings. By default, we can consider that you are only able to comment on your friends’ walls. In the specific case of Fan Pages, the fact that a user likes it does not mean that you can comment on his/her wall. The criterion here is the friendship level between the Fan Page’s owner and the user.
Results capture:
Twitter:
In most of the situations on Twitter, the results capture is limited to what is indexed by search.twitter.com. The cases that a result is not indexed include:
- The language of the tweet was not identified as being the same as the language searched.
- The user has a closed profile (non-public)
- The user has a profile that it was excluded from the Twitter Search
- The post is very old (more than 6 days ago)
- The searched item is a user’s name mentioned on an automatic retweet
Facebook:
There are two main information sources for posts on Facebook. The first of them is the post general search. The information captured in this kind of search is limited to posts from users who set their wall information as public (everyone). This is the default setting for users joining Facebook.
The other information sources are the posts on their own wall. Inside this scenario, it is possible to obtain all public posts. Pay attention to the pages with age limitations, accessible only for users older than 18 years old, for example. They become non-public automatically.
