More on metrics..by Prasant Naidu

Social media today is not only about having a meaningful community but it is also about monitoring and measuring. Measuring social media activities has always been debated upon and will continue to be. One of the reason is that we are measuring sentiments of human beings. A bit difficult but tools are getting smarter day by day.

Facebook, one of the largest social networks of the world is also home for more than 37 million brand pages with more than 10 likes. Most of the brand pages till date have abided to an engagement formula that considers your Likes, Comments and Shares, as shown below:

Why the present formula needs a revision?

The above formula has been popular for a while but has some hidden problems that was recently listed by WiseMetrics. WiseMetrics, a company that is also in the business of measuring the ROI for Facebook brands has listed 5 flaws in this formula:

1. It doesn’t include all interactions: The above formula only considers likes, comments and shares. The formula completely misses out the video, links and photo clicks by fans on Facebook.

2. It is based on number of fans: The formula considers number of fans but what about friends of fans. Social media is about reach and by calculating only number of fans the formula ignores a vital thing.

3. It is mixing fans data with fans and non-fans data: The formula takes into consideration a ratio out of interactions (made by fans and non-fans alike) with total number of fans only. In other words, it is deriving a ratio of the total number of likes, comments and shares made by fans and non-fans from the total number of fans. A confusing way of doing it!

4. It favors pages with high publishing rate: The current formula can be tricked if you post more, as shown in an example by Wisemetrics.

So it clearly shows that the more you post, the more engagement can be driven by brands on Facebook, forgetting the definition of spam.

5. It measures interactions only and not users: The given set of formula is only measuring interactions without even considering unique visitors.

It clearly reflects that the formula of engagement that has been only focusing on likes, comments, etc. needs a revision. Hence, a new formula has been developed so that it can take care of the existing shortcomings.

New formula provided by WiseMetrics

The above formula has been derived by the team at WiseMetrics and it solves the issues in the current formula.

Is the new formula better?

The new formula that has been proposed is better since it is not considering only posts and comments but it is taking into account the total number of posts posted on the page.

The formula is also taking care of fans and non-fans since Facebook allows you to comment or like without even being a fan. So it makes sense to consider users reached rather than talking about only total number of fans.

To add to this, the new formula proposed by WiseMetrics is better than the one that SocialBakers uses to measure ROI on Facebook. SocialBakers has two formulas to measure the ROI – 1) Average Post Engagement Rate and 2) Daily Page Engagement Rate.

The above figure shows that the Daily Page Engagement Rate is similar to the generic Facebook engagement formula. Even though the formula talks about per day engagement, it should reconsider two basic factors:

1. Only considering fans and forgetting non-fans

2. Only considering likes, comments and shares

Can the formula proposed by WiseMetrics be better?

Definitely the formula proposed by WiseMetrics is the way forward when you are considering ROI of your Facebook marketing. However, there are still some missing links that need to be taken care of when we are talking about measuring Facebook engagement.

1. You can’t evaluate likes and shares as one set: We all know that sharing articles is a bigger task than liking an article. So can we quantify them differently and produce better scores?

2. Considering all comments is vague: In general, I have seen most of the times the comments are not with regards to the posted content. So can we calculate only those comments that are aligned to the post content?

3. Talking about this’ is vague too: The figure “talking about this” is a vague one again as it just states how many people (fans and friends of fans) are simply talking about the brand and does not give an idea about the nature of their conversations. A brand needs to know the sentiments behind the engagement, while it is calculating the ROI on Facebook engagement.

I understand these are early days and it will take time for tools to evolve. But the present formula for calculating engagement is full of flaws and we need to take a look at the one that has been provided by WiseMetrics. It answers most of the shortcomings.

  1. “The [above] formula presents the following benefits which makes it a lot more accurate” – but just to clarify to match up with the terms Facebook uses:-)

    – It includes all type of interactions : photo views, video plays, link clicks, quotes… Not only likes, comments and shares. <That is all interactions with your FB Page from ‘Users Engaged’ = both fans + non-fans – aka ‘Talking About This’ figure
    – It compares fans and non-fans engagement (Users engaged may or may be not fans) with total number of fans and non-fans : Users reached <aka ‘Weekly reach’ figure
    – Only people who had the opportunity to see your content (thus the opportunity to interact with it) are included <live numbers
    – The impact of publishing rate is isolated <the number of posts

  2. (1) In Wisemetrics the Facebook Page engagement key stat: ‘Talking about this’/ number of your page posts/ ‘Reach’ x 100

    (2) In Facebook Page stats: ‘Reach’ / ‘Talking about this’ x 100 = ‘Virality’ %

  3. Correction from Wise Metrics – confirming that you need to export the Insights excel to obtain the terms/figures:

    Nope. We’re using Facebook’s own terms. The data may not be available directly on Insights, so you need to export Insights’ data into Excel.

    “People Talking about this” and “engaged users” are totally different metrics and we don’t advise using PTAT in any engagement rate calculation as it contains flaws the same way the “Likes+comments+shares” has.

  4. Q: Wonder if this is really from the folks at Twitter itself?

    Tell me please, do I understand correctly: ‘users engaged’ we divide by the amount of posts, and then the result we divide by ‘users reached’ and then we multiply the result with 100?

    I get in results – 0,50%. that’s weird
    (961 / 23 / 8249 *100 = 0,50%)
    is it wrong, isn’t it?

    but if I divide the ‘users engaged’ by ‘the users reached’ and then multiply with 100 I get the: 11,64%
    that’s sounds ok

    what do you think about it?
