Travel companies may be scratching their heads over a sudden drop in attention to their Facebook fan pages - a problem TravelRepublic has admitted to this week.
The UK-based online travel agency says it has experienced a huge drop in impressions from messages it has posted on its Facebook page over the past few months.
Typically, it claims, a message would get 100,000 "impressions" (number of times an update is seen on the fan page wall and in the news feed of fans) on each of its messages, but data has shown the figure plummet to around 50,000 per message.
This is against the backdrop of the number of customers becoming fans of the page increasing to over 50,000 in recent months.
TravelRepublic reckons it has fallen victim to a recent change to settings on Facebook where users can opt to only see messages in their timelines from friends or fan pages they interact with the most, rather than all their connections.
Users are being urged - via a message on the TravelRepublic page - to change their settings, although the company concedes many of those fans will obviously not see the message anyway.
Clearly incensed by the change, TravelRepublic says it has recently contacted Facebook to try and discuss the matter further.

"We’re pretty confident that we’re not alone in being a brand with a sizeable Facebook following who is troubled by this large reduction in the level of interaction with its fans. It will be interesting to see what they say."
