"one of the cheapest dividend ETFs, with an expense ratio of 0.26%. Some rivals charge as much as 0.60%. But fees aren’t everything here. VIG’s current yield — slightly less than 1.6% — is on the low side, as is its total return of roughly 7% since its inception in late April 2006."

"...the first dividend ETF, has gathered more than $7 billion in assets. It invests in 100 of the highest dividend-yielding securities (excluding real estate investment trusts) in the Dow Jones U.S. Total Market Index."

"invests in the top 100 stocks of the Morningstar Dividend Leaders Index. These are the index’s highest-yielding stocks, ranked by the consistency with which they pay dividends and the ability to sustain those dividends going forward. Three securities — Citigroup, Bank of America, and Altria — together make up more than one-fourth of the fund."

"invests in the 50 highest dividend-yielding S&P Composite 1500 constituents. This index tracks equities that have consistently increased dividends every year for at least 25 years. Investing in these long-term dividend-paying stocks reduces the risk that the fund’s holdings will cut their dividends."

"aims to double the yield of other dividend-paying ETFs. The fund invests in high-yield securities such as preferred shares, master limited partnerships, closed-end funds, American Depository Receipts, and real estate investment trusts. It’s a riskier play, since the holdings don’t all have a long history of regular, stable dividends"
