FYI: When it comes to holding an ETF, the expense ratio is all-important. When it comes to trading an ETF, another number matters more: the bid/ask spread.
The spread between the bid (the highest price a buyer is willing to pay), and the ask (the lowest price a seller is willing to accept), is a significant part of an ETF’s trading cost. (Trading costs are reflected on ETF.com fund reports.)
