Android Income Report #4: August 11

Another month is over, it’s time for income facts again.

If you are new to this series, let me explain it to you: Since Android is an open platform, I decided to be open about the income I’m making with my private Android apps too. In the last report I aimed to reach $1,005.02 for the last month. You will see if it worked out.

Which Apps?

3D Invaders – about 100.000 installs (+8k), 16% active

AL Voice Recorder – about 382.000 installs (+23k), 24% active

AL Voice Recorder Ad Free – 721 installs (+31), 41% active

Droid-Blog.net Android App – 186 installs (+66), 30% active

SmsToSpeech full – 675 installs (+19), 42% active

What did I do?

Essentially nothing. I neither published a big update nor a new app. Still, more than 30.000 new users downloaded my apps.

The Droid-Blog.net app had a huge increase in download numbers again (55%)! Furthermore, after being in the Market for more than two months, it finally got its first click grossing a total of $0.03. Hurray!

Advertising Stats

Here are some statistics from the two advertising networks I’m using, AdMob and Madvertise. Please read the second income report for an explanation of the following numbers.


Requests: 438,914 (+23k)

Impressions: 420,452 (+12k)

Fill Rate: 95.79 (-2.48%)

Clicks: 8,399 (-2.79k)

CTR: 2.00% (-0.74%)

eCPM: $0,91 (-$0.17)

House Ads: 22,309 (+16.8k)

Adjusted Requests:  461,223 (+40,5k)

Adjusted Fill Rate: 91.16 96.98% (-5,82%)


As I’m not using house ads in Madvertise, no adjusted requests and fill rates are shown here.

Requests: 250,609, (-91k)

Impressions: 53,472 (-12k)

Fill Rate: 21% (+2%)

Clicks: 2,874(-440)

CTR: 5.37% (+0,3%)

eCPM: $10,28 (+$3,76)

My AdMob performance regarding impressions and request was not bad, but the fillrate and the eCPM was. While Madvertise lost about 91,000 request compared to the previous month, it was able to compensate this by having an enormous eCPM.

How much?

Did I manage to reach my goal again? Here’s what I earned:

Madvertise: ~$550.35 (+$124.28)

AdMob: $380.68 (-$58.88)

Market sales: ~$89.31 (-$41.45)

In-App purchases: ~$8.23 (-$0.40)

Total: ~$1028.57 (+23,55)

Goal reached! Why? I would say mainly because of the weak dollar. While one Euro was worth 1.4 dollars one month ago it is now worth $1.44. This made the small difference between success and failure.

What’s next?

I’m curious if Madvertise will be able to keep up those great numbers. I will be pushing some updates this month, so I hope the download figures will increase to about 33k again. My goal for the next month is $1,100.

Downloads, Advertising/Promotion and Time

Richard just asked a good question on the income report #1 post:

“how long did it take, to get that number of downloads for your free apps? What kind of advertising/promotion did you consider? Have you advertised them? Would be interesting to read about the ascent of your downloads over time…”

I think this might be of general interest, so here are my answers.

The AL Voice Recorder started on 4th of July 2010, so it has been in the Market for about a year now (~335.000 downloads). 3D Invaders was released on 29th of November 2010 (~80.000). For both apps I did not do any paid advertising. What I did was App Store Optimization and social media marketing (blogs, forums, twitter, etc.).

I recorded the downloads of the AL Voice Recorder for five of months, here is the result:

On 07th of November 2010 I made an App Store Optimization and the app was ranked #1 for the search query ‘voice recorder’ since then. You can see the huge increase in downloads on the chart.

My impression on advertising is that it is only usefull when you are able to spend enough money for being present for a longer period of time. This will sure have an effect on your download rates. Most developers spend $50 on their apps and then say “AdMob (normally it’s AdMob) burned my money!”. Of course you wont see big results when spending $50 for an ad campaign. Assume that one click costs $0.05 and the conversion rate is 10%, than that’s 100 new downloads for $50 (or $0.50 per download). I think advertisements in mobile ad networks are necessary as a part of huge ad campaigns, including social media presence, ASO, viral marketing and so on. When relying on ad networks only, the success will probably not be that sustainable.

I hope this was helpful, please feel free to leave comments.
