Seasonal keywords are tied to certain times of the year, like holidays or events. One way to find them is by thinking about when people are more likely to buy certain products, such as gifts during festive periods. Google Trends can also show when interest in a keyword rises and falls. Looking at past content performance can help too. Planning early is important because content needs time to rank. Catching the trend at the right time can bring good traffic. How early should seasonal content be prepared?
