Before you search for the best dividend exchange-traded funds (ETFs), it is recommended you understand your needs and overall investment objectives. ETFs are hybrids of mutual funds and stocks. When you invest in the ETF, you purchase shares in the fund, which buys the underlying asset.

Here are six of the best high-dividend ETF funds:

Vanguard High Dividend Yield (VYM)

This ETF adopts the simple method of choosing stocks that have higher dividend yield when compared to other companies.

Vanguard Dividend Appreciation (VIG)

The ETF focuses on investing in companies that have a long history of increasing their dividend payouts over the years. The portfolio includes approximately 180 stocks with low yields. The ETF has earned average returns of 12.6% per year over the last 10 years. The expense ratio is 0.06%, which makes it an excellent option if you do not mind lower dividend returns currently but want to earn more in the future.

WisdomTree U.S. MidCap Dividend (DON)

This ETF invests in companies with a low market capitalization. Almost 70% of its portfolio companies have a market cap between $2 billion and $10 billion. Even the larger portfolio companies are the lowest in the large-cap segment.
