In addition to dividend history, it is necessary to check such indicator as Dividend Payout Ratio (DPR) https://a2-finance.com/
. It allows us to understand how much of the company's net profit is allocated to dividends. The DPR value should be between 40-70%.
If the DPR is greater than 100%, it is a red flag. It warns that the company is directing all of its profits to dividends, and has nothing left for business development. In such a case, to pay dividends the company can get into debt or it can choose to reduce or maybe even stop payments.
