Dividend stocks have become crucial to generate income for many investors, and many have turned to the Dividend Aristocrats as a source of investment ideas. But there's one key fact you need to know about Dividend Aristocrats before you simply pick a stock from the list and expect it to meet all your needs.

In the following video, Dan Caplinger, The Motley Fool's director of investment planning, explains how Dividend Aristocrats can fail some investors. Dan notes that dividend growth is an essential component of being a Dividend Aristocrat, and stocks on the list have raised their payouts annually for at least 25 years. But Dan also points out that there's no minimum dividend yield for an Aristocrat, using examples of Sherwin-Williams (NYSE:SHW), Franklin Templeton (NYSE:BEN), and Ecolab (NYSE:ECL) with yields in the 1% range. For many investors, yields that low won't meet their income needs, and Dan concludes that you have to look beyond the list and find out exactly how much income you can expect from any given Dividend Aristocrat before deciding whether it's suitable for your portfolio.
