Class might be dismissed for the summer, but now is the time for advertisers to hit the books and prepare for back-to-school season. Unlike the holiday shopping season with its well-defined shopping window, back-to-school presents a more complex terrain for advertisers to navigate. The shopping window begins as early as July but drags out longer, with peaks and valleys that vary based on shopper persona and category.

Bazaarvoice has put together a helpful infographic to help marketers set an A+ digital advertising strategy informed by the complex seasonality nuances of back-to-school season.  A few of the big trends to watch this year:

• Back-to-school shoppers are spending more
  
• Different back-to-school categories have incredibly distinct seasonality trends
  
• Shoppers are doing their homework (that is, researching products) beforehand
