how to improve article citation ?

Hello,

Now I keep contributing articles to related journals to 'preprare' for being qualified for Eb1
I have some questions:
a) do I MUST contribute article to journals ONLY? (what about blog or any computer website?)

b) is there any trick to improve citation rate?

c) Some of my articles are short (2-4 pages, while essential), is that OK(I mean not so many quotations as formal graduation dissertation)?

thank you
