thanks guys for your replies
however, i have a question about the long tail keywords!
let's suppose we consider the keyword "flappy bird" as an exemple
a quick search reveal that "flappy bird online", "flappy bird multiplayer" and "flappy bird mmo" as keywords with less competition + as long tail keywords (exact match).
if we repeat those keywords x3 times in the long description it will be :
- "flappy bird online" x3
- "flappy bird multiplayer" x3
- "flappy bird mmo" x3
but the problem is that now we have the main keyword "flappy bird" repeated 3x3 = 9 wich is bad as i guess (more than 5), google search bots will certainly detects your app as you trying to spam.
what's your advice?
