I created a few applications. One of them is very good and users like it. However, I can not increase the number of installations to more than 50 per day. It is very small. The program is unique, complex, but very useful.
Within one month I did:
But all these had very weak effect. Now, the app has 1700 installs. A month has passed!
What else can I do? Maybe my translation of texts so bad? English is not my native language and I know it badly.
Marketing Advertising Apps Android
Search for App Store Optimization in google, it's a new branch of SEO which is catching on and is very relevant to you.
Also look at AppAnnie.com to receive insights about apps and your ranking in different locations, that way you can know where to focus your marketing efforts in localized versions or what not.
I would also recommend doing some A/B testing with application name as key-word optimized app names will appear higher.
Or you can try the following:
1) "Not so honest way": make a lot of google accounts, get the market install on emulator, download and rate 5 stars on your own app. Write your own nice reviews.
2) "More honest": embed in your app the reminder to rate. Don;t show it right away but after some time.
Or try AppSurfer. Know more here - http://appsurfer.com/developers It helps market app, tries to increase downloads for publishers.
P.S. I am associated with AppSurfer.
