If you’ve been running your Facebook page for a while and often take a look at Facebook Insights to see how your page is performing, it can be a real boost to see the steady growth in fans that your page is getting.At the same time, it can hurt to see those small red spikes that show a number of fans unliking your page – especially if you’ve just posted that meme gif that is doing the rounds at the moment and you thought would perform well.What if you could find out the reasons where the people who like your Facebook page come from?Or even more importantly, why they unlike your page?There’s a hidden feature in Facebook Insights that might be one of its most important parts in informing your Facebook strategy. But not many people know it even exists or where to look.We’re talking about the Page Like and Unlike Sources tab, which shows you exactly where your page likes and unlikes came from.There’s a step by step on how to find and use the tab below, but it’s accessed from the “Net Likes” area of Facebook Insights.Facebook insights already provides lots of useful analytics around how your Facebook page is performing, but looking at the sources of where your page likes and unlikes came from is particularly useful when planning your social media strategy.For example, keeping a close on your Facebook Page likes and unlikes gives you a good idea if the content you are posting is resonating with your audience.If you see a steady increase in page likes, you know you’re on the right track. But if you see a spike in unlikes when you post “hilarious” cat gifs, then it might be time to rethink your content strategy.What does the Facebook Like Sources Tab Tell You?So what kind of information can you get from the Page Likes and Unlikes tab?Below is a list of the like and unlike sources that Facebook gives you.Unfortunately, Facebook doesn’t tell you what each one means, so our team has taken an educated guess as to what each definition means.For page likes, Facebook breaks down your fan acquisition into the following categories:Uncategorized Desktop: Likes from users using Facebook on desktopOn Your Page: Likes from users visiting your Facebook page directly and clicking the Like button in the page headerPage Suggestions: Likes from pages suggested when users either like a page and are shown related pages by Facebook, or are shown pages that might be of interest in the right-hand columnAds: Page Likes gained from Facebook Advertising you’re showing in the Facebook news feed, which contain a “Like Page” option in the top right cornerUncategorized Mobile: Likes from users using Facebook on a mobile device or tabletAPI: Could mean the Like button on your website, or from an appYour Posts: Posts you’ve published and that people have seen in the newsfeed. Most likely from existing fans sharing your post with their friends, who then go on to like the page.Search: Users searching for and then liking your page using Facebook’s search featurePosts to Page: Page likes from users users posting to your pageFor page unlikes, there are less options, but they’re still just as useful:Suspicious Account Removal: Facebook cleaning user accounts that are fake, malicious or just plain suspiciousOn Your Page and Posts: Users unliking your page after seeing a particular post, or visiting your page directly to unlikeDeactivated or Memorialized Account Removal: People who have left Facebook or where Facebook have been notified that someone has passed awayAfter Hiding a Post: A user has seen your post in their newsfeed, hidden the post so they don’t see your content again, then unliked your pageYou’ll also get a percentage breakdown of the likes and unlikes on any given day, plus the actual numbers of fans you’ve gained or lost.When reviewing the stats with our clients and Empower’s Facebook page, we were concerned that a lot of page unlikes would come from the Facebook ads we had running at the same time. After all, many Facebook users get upset when they see ads forced into their newsfeed, so we’d expect this to be the biggest source of page unlikes.However, we were pleasantly surprised as we found that most page likes came from suspicious account removal – a sign that Facebook is doing its job in removing fake accounts, plus a sign that our content strategy was working.
