it is funny how this post became an extension of the Wish and Bugs sub forum...
well some recomendations would be:
1.- add ads or even add more ads (if you are already promoting this way) because when i begin to look for solutions for android, yours never appeared in any banner! i received a lot from xamarin and visual studio and some others...
Actually it was funny how i found Anywhere Softwere, it was because of a forum where everybody was attacking Delphi and embarcadero, some user mentioned (it was not a very positive comment by the way) B4A, i decided to look and here i am!! lovin it!
2.- Become more social? before buying i look for the words: Anywhere software, Erel, B4A, etc. I remember one interview with tech magazine and that was all no more social appearence!! i remember a company, i think it is remobjects, who´s CTO were all over the internet solving problems and talking about their products, but literally, everywhere.
2.1 be in Wikipedia, Github and any other social-knowledge communty, i have ever wonder why the libraries you release (of course not all) are not in github, may be doing some libraries and let other people improve it this way, the more it extends beyond the B4x.com webpage, the more results will fill the google search page.
3.- force the users to use it? in the trial version of B4A you could bundle B4J with several examples of point and click! Be more aggresive?? for example 3 mins to setup B4A (instead of the 5 seconds it takes now) with images of what B4J could do. in other words, becoming evil???
4.- Making some charts where: why B4J is better than visual studio or xamarin? (this kind of charts are very attractive to the search engines) people love to compare, they always feel smarter if you present choices instead of solutions.
5.- Newsletter with information of the Advancements of B4J and what other users are doing with it, this newslatter could go to the people that registered for the B4A trial.
6.- i do not know the effects of this idea, may be i already consumed to much coca cola, but i have seen some post where you upload a B4J App on the internet (like the jsontree). may be offering a host B4J-ready to install apps, use of databases etc. etc. would attract people. imagine! Host your push server for android and ios for as low as $1.99 month! that would be engaging.
