Because digital marketing has so many options and strategies associated with it, you can get creative and experiment with a variety of marketing tactics on a budget. With digital marketing, you can also use tools like analytics dashboards to monitor the success and ROI of your campaigns more than you could with a traditional promotional content -- such as a billboard or print ad.
On the other hand, marketers who employ digital inbound tactics use online content to attract their target customers onto their websites by providing assets that are helpful to them. One of the simplest yet most powerful inbound digital marketing assets is a blog, which allows your website to capitalize on the terms which your ideal customers are searching for.
For that reason, you're probably less likely to focus on ‘leads' in their traditional sense, and more likely to focus on building an accelerated buyer's journey, from the moment someone lands on your website, to the moment that they make a purchase. This will often mean your product features in your content higher up in the marketing funnel than it might for a B2B business, and you might need to use stronger calls-to-action (CTAs).
If you get big enough, yes, you’ll be in every channel eventually. But in my experience, businesses diversify across channels way too early. Especially with online channels, the level of competitive has gotten very high. It’s almost impossible to compete at the highest levels on SEO, social, and paid at the same time. Most marketing teams are only good at one channel which subsidizes the rest.
