What Are The Various Credit Card Hack To Increase Credit Score?

[Sam Walton]

I was reading an article where it was informing on how to increase my credit score and all that stuff. It was a good one but I'm curious to know what things people do to increase their credit score using credit cards. How many credit cards we can have?

Personal experience has been bit weird,
Everything in report shows improvement over previous report but overall score decreases.
it again increases next month.
If you ask them(the credit score body), they send generic answer.

But in general:
1) Pay complete bills on time (long term impact)
2) utilise <30% of limit
3) dont apply to a lot of cards within short duration
4) more the age of credit card, it has better impact
Having a lot of credit card does not have a significant impact on score
