Halloween has become one of the hottest search trends in recent weeks, and the National Retail Foundation reports adults are increasingly spending online for this costume-filled holiday.

Halloween spending in the United States totals more than $70 per adult in the United States, as people stock up on costumes, candy and other supplies, according to the National Retail Foundation. For web marketers, developing a keyword strategy that integrates the popularity of Halloween and other seasonal holidays into content can help boost SEO campaigns.

The NRF reports that consumers are spending more money online for party supplies than they did previously. Like most ecommerce, research for party supplies frequently begins at search engines. Marketers at party supply companies, using can use content marketing campaigns aimed at providing information and original content can to help boost SEO rankings while also providing valuable information for visitors.

Of course, maintaining content relevancy will be key to effectively winning visibility based on Halloween search trends. Search engines only reward content and websites that mention trending topics appropriately. As searches for terms pick up at certain points of the year, businesses using content marketing campaigns to drive traffic can take advantage of these trends if they find the right angle to make the topics relevant to their target audiences.

Brafton reported last month that even before October began, Halloween had become a trending topic, according to Google Trends.
