Then what is the main factor?

If and If I buy a stock for a dividend, I wish to be sure that I want to get MORE dividends each year.

I wish and I dream of lots of things ... all the time.
Jokes aside (ahem!), I think everyone wants at least the same or more dividends each year.
They do not want to invest in a stock only to find it slashing its dividends the following year.
In short, the sustainability of the dividends is just as important as the the dividend yield.
In terms of sustainability, this sifu
gark, has covered already.
Things like cash flow is important.
Profits is important too.
When a company earns less money, chances are they will cut its dividends the following year.
As we saw in Panamy case, when a company earn less, subsequently the dividends shrank (despite of the cash balance).
Knowing the company background and history and its owner history is just as important.
As discussed before, Panamy is not going to be super nice and distribute that huge cash balance it has in its books, since the money is deposited (or is it lend) to its holding company.
As said before, a stingy owner can surprise the market with a huge generous dividend but such dividend is not going to be repeated cos the owner will remain stingy.
