Every year is marked by huge innovations and emerging trends that change the digital marketing landscape. With 2014 in the rearview mirror, it's easy to look back and see that many of the changes that altered best practices were forecast in 2013 and even earlier.

Although new trends have dramatic implications for how marketers do business, savvy professionals don't need to feel blindsided. The top digital marketing trends for 2015 have already taken root, and there's no good reason to be skeptical about their bright futures.

By accepting the changes yet to come and planning to attack these trends head-on, marketing departments can get a nice head start on their competition. Here's what to look for this coming year.

Integrated marketing campaigns that combine traditional advertising methods like print and TV with online advertising outlets like social networking websites have become increasingly popular in recent years, reaching today's connected consumers in more ways than ever. If a marketing campaign in today's world is truly going to be successful, it will need to reach out to consumers in many different ways, including print, TV and online to be successful. Integrated marketing campaigns can be of different sizes and scopes, but there are two big advantages these types of marketing campaigns have over traditional or digital-only advertising.

With the constant increase in the number of TV channels, radio, print media, billboards and sponsored ads out in the world, you may feel like you need to take a scatter gun to your marketing message: If you target every direction, surely you'll hit some — if not most — of them, right?

This isn't the case, according to experts at Target Marketing. Launching a marketing campaign with a consistent logo, slogan and message delivered across different media will no longer cut it, and you could find that dreaded problem emerging — fragmentation.

What Is Integrated Marketing?

According to Integrated Marketing Week, integration means "No single channel can win out anymore. ... [Marketers must deliver] great customer experience through truly integrated marketing, across any and every channel: Web, social, mobile, broadcast, print, email, in-store, outdoor and beyond."

When we talk about digital marketing, we're not simply talking about a singular strategy to help you gain clicks. Digital marketing is an umbrella term for dozens of different strategic campaigns that are designed to increase visibility and traffic to your business. A single campaign on its own will yield some results, but they will pale in comparison to the opportunities created by a multifaceted digital strategy.

Budget and other resource constraints are always a factor in determining what strategies a company is able to implement at a given time. However, the relative cost-effectiveness of many digital campaigns means that you should be executing a combination of campaigns for your business. Here are some of the top methods for converting digital opportunities into tangible growth.
