@CityofCT (COCT) has more Twitter followers than @CityofJoburgZA (COJ). Notice that the 2 Twitter handles share just under 7 000 followers between them. In our experience, this indicates that the two accounts have (or are perceived to have) little in common, hence they share such a small number of followers. Accounts that have something in common – e.g. South African low-cost airlines Kulula and Mango, share a higher number of followers between them.
City of Joburg's Twitter follower growth target
On the 18th of March 2015 we had a Hangout on eNitiate Visual Radio – our weekly Internet radio show that is currently hosted on Radio Junto – with COJ Group Communications Social Media Manager Tumelo Komape about Africa’s world class city’s social media performance. Tumelo indicated that COJ’s Twitter account is growing at 8 000 Twitter followers monthly, and that he is targeting 100 0000 followers by June 2015. Our back-of-match-box calculation indicates that this is arguably a soft target at current performance levels. Let us show you why we hold this view, using a few analytics tools with complementary findings.
Forecasted comparative Twitter follower growths
If an assumption is made that both COJ and COCT are going to grow at the same average daily rate for the period to 20 June 2015, then COJ will grow its Twitter followers to 101837. Thus, Tumelo’s target is a soft one.

While COCT will still be ahead in forecasted number Twitter followers, this may not last forever if if the 2 metros maintain their current Twitter content strategies. We explain what we mean in the rest of this post.
Social influence
The COJ and COCT are doing well on Twitter as indicated by their healthy Klout scores.

In simple terms, Klout score is a measure of a Twitter handle’s level of social influence. A score that is close to the maximum of 100 is highly desirable.

As the 2 tweeting behaviour graphs above show, COCT engages 1,3 times (REPLIES + RT) for every 1 tweet, while COJ engages 0,67 times for every 1 tweet. Put differently, COCT engages more, while COJ broadcasts more. On the surface, COCT is doing well by being a chatty Twitterer than COJ. However, a deeper analysis indicates that COJ’s social content has higher potential of being more engaging than COCT.

- If COJ’s mentions include the power users, then this will increase reach for its content, which in turn has a positive correlation with increase in new followers. Thus, COJ’s social content strategy that incorporates tweet mentions can bear desired results.
- COJ’s tweet content has higher percentage of pictures than COCT’s. According to Socialbakers‘ recent finding, pictures get most engagement of all types of content on Twitter.

- Clearly COJ’s twitter content strategy is on the money.
Our conclusion
Using current social media marketing initiatives by @CityofJoburgZA and @Cityof CT as a predictor, our conclusion is that City of Joburg’s Twitter follower base is going to surpass City of Cape Town’s base in not too distant future.
