A search for “candle burning times” indicates a person who needs more infomation before making a purchase. Instead of sending them to a product page, provide the information they need, then send them to the appropriate product. Take time to provide needed information before asking for the sale.
The specific suggestion not included in this quote is to create a landing page with a table that shows different burn times for different types of candles in your inventory. This content can then be linked to your various product pages.
