I keep reading that more and more companies are increasing their digital marketing budgets. Should we follow this trend ?

Don’t follow the heard, blaze your own trails. It really depends on just how important digital marketing is to your customer and product category. Look in your fridge or pantry and tell me how many of those products you really have time to research online ? However consumers will spend time online researching products like insurance, automobiles, electronics and even some clothes. You need to understand what is the most important consumer touch point that turns them into a customer of your brand.
