Facebook announced today that it has discovered a number of bugs that impacted Page Insights impression and reach reporting. Facebook is now in the process of fixing these bugs, but wants developers to know that the impact of said bugs will be different for every page. To see the results of the fixes and the impact the bugs had, Facebook recommends you check your page Insights on Monday after a weekend of bug fixing.

So, what should you be looking for? Facebook says that most Pages will see the following changes on Monday following the bug fixes:

Unfortunately, Facebook says that it won’t “be able to backfill Page Insights with historical data” as a result of the bugs mucking with its logging systems. Everything else should be working fine once the bugs are all fixed by Monday morning though.

Facebook announced today that they’re making some changes to how user feedback is analyzed. They’re also changing their response to apps that receive an enormous amount of negative user feedback. Every app deserves the benefit of the doubt and Facebook is finally giving it to them.

First up, Facebook is rolling out a “News Feed” tab on your app’s Insights page. It will display both positive and negative feedback so you can make the necessary corrections before Facebook throws your app out on the curb. The new graphs use a familiar red and green color combination to show the general outlook users have in regards to your app.

The new Insights options perform a secondary purpose beyond giving you a general idea of how an app is performing. It’s all part of Facebook’s new “Granular Enforcement” plan that will gather feedback on each separate part of your app. In short, Facebook can now shut down a single offending part of an app instead of the entire thing.

For example, Facebook says they can now shut down a spammy chat action instead of the whole app. It protects the developer from having their entire app wiped while simultaneously protecting users from shady practices. Developers will of course be able to appeal Facebook’s enforcement.

What happens to apps that are just terrible across the board? Is Facebook still going to wipe them? The company says that they will now put these offensive apps into a new “Disabled Mode.” This will remove the app from Facebook, but allow the developers to tinker around with it on Facebook. Developers will have access to everything in their app including tests, settings and Insights.

These changes are leading up to Facebook’s new discoverability model. When introducing App Center, they said that quality apps will get top billing while poor quality apps will get shuffled to the end of the list. These new Insights will help developers focus on making the kind of quality apps that will push their product to the top of App Center.

The new Insights features are all about unique users. You might get a whole lot of visits to your app on Facebook, but chances are they are not all unique. The higher count of unique visitors equates to your app being more popular. Think of it in terms of a band – it’s great to have a dedicated fanbase, but it’s even better to have a larger, more diverse fanbase even if they don’t show up as much as the dedicated bunch.

So that’s why Facebook is introducing unique visits to Open Graph Insights. It was impossible before to see how many unique people were sharing Open Graph stories with an app. It could have listed 10,000 stories published, but it could have been the work of one crazy obsessed fan. I’m sure you really like that fan, but you need more than just one guy to grow an app. The new Insights breaks it down by unique views over the course of 30 days. Here’s what it will look like:

What’s even cooler is that the Insights change when you limit the time frame to a single day. It opens up detailed unique user information like published actions, unique impression vs. total impressions, number of users clicking and more. Check it out:

The unique user Insights has also been extended to authorization dialogs. You can now see how many unique users have accessed the authorization dialog and how many went through with the installation. Even more impressive is that it breaks down unique users even further by each permission set. That way, you can see which users are more accepting of which permission set.

Like I said above, unique users are super important. It’s great that Facebook is now letting app developers track the number of unique views, shares and hits they’re getting. They can now use these numbers to plan future updates based around the more popular options.

The new rating parameters will show up in Facebook Insights. The first addition is the ability to rate apps. Every app will feature a little rating card where users can give an app one to five stars. It’s the closest we’re ever going to get a dislike button so be sure to take advantage of it.

Developers will be interested to know that Facebook will not only be tracking the ratings through the card, but a full fledged Insights chart. It will track the amount of stars your app receives from various users and plot them based on the number of stars you receive. The example shows an overwhelming selection of five star ratings, but I know the Internet too well for that. People are going to one star bomb a lot of the more popular apps on Facebook.

If that wasn’t enough, they will also break down your star ratings by demographic. That’s right, not only will Facebook tell you that an overwhelming amount of people gave your app three stars, but that most of those three stars ratings came from the tiny island nation of Samoa.

If there’s one thing that the Internet likes more than giving one stars to perfectly fine products, it’s leaving negative feedback for products. There will be a new chart in Insights that will track the amount of negative attention your app has received including those who hide stories from your app, mark them as spam, or even blocking the app.

Interestingly enough, Facebook will be using their spam filter to monitor the amount of negativity emanating towards your app. This information will be compared against the total number of impressions to give you a good idea of how many people love your app compared to how many people hate it.

Finally, you can also use breakout dashboards to analyze specific content. With content streams, you can see how users and non-users are interacting with content. Open Graph stories can be analyzed down to specific action or object types. These options will allow developers to get down into the nitty gritty of Facebook options.

Jokes about small island nations and one star bombing aside, these are great new tools for developers. The App Center is going to change a lot of things within the app experience for the user and the developer. These tools are an excellent bridge between the two that allows the user to directly tell the developer how they feel.

BuzzMarketing Daily discovered that there is a blurb in the Fan Interaction Dashboard, which you can get to by clicking "learn more" from the Facebook Insights page, which talks about a couple of new metrics that are on the way (via Inside Facebook).

The new metrics are Click Through Rate and Engagement Rate for content that appears in the Facebook news feed. As described in the blurb, if a user clicks on one of your posts, it will be counted as "Stream CTR" and if a user likes or comments on a post, it will be counted under Stream ETR.

One knock against social media marketing has historically been its lack of measurable success. Metrics like this should be able to go a long way toward curing that.

With Facebook’s Insights, you can already look at interactions (numbers of comments, wall posts, and likes), Interactions Per Post (average number of comments, wall posts and likes for each piece of content), Post Quality (score measuring engagement), Discussion Posts (number of discussion topics created on your page), and Reviews (number of times fans use the Reviews app to rate you page).

Suffice it to say, there are a number of things you can look at to gauge the success you are having with your Facebook page, and depending on what areas you are lacking in, you can take the necessary steps to try and improve – just like with any other analytics program.
