Top 6 Best Marketing Consulting Firms | 2017 Ranking | Best Marketing Consultancy Firms for Marketing Consulting Services


Finding the Best Marketing Consulting Firms

Marketing consultants are highly skilled in understanding what motivates consumers, how to target an audience, and what measures a business can put in place to more effectively reach their desired consumers.

There’s some level of interchangeability between a marketing consulting firm and an advertising firm. However, an advertising consultant or firm helps companies find innovative, creative ways to reach new potential customers and markets within the framework of one campaign or a short-term objective.

By contrast, a marketing consulting firm helps clients use analytics, technology, and data to explore the present state of their business and see how they can more effectively engage existing customers over the long term.

Additionally, a marketing consultant goes beyond simply advertising or public relations and instead takes a more holistic view of a business based on analytics and the development of strategic objectives.

Marketing consultants not only implement strategies; they will also measure the effectiveness of said strategies to refine marketing plans over time. This makes the top marketing strategy consulting firms into extremely valuable partnerships for any business in today's economic landscape.

When Do You Need to Hire Marketing Strategy Consulting Firms?

If a business is unfamiliar with the goals and practices of marketing strategy consulting firms, it can be difficult to know when to bring on the skills of a top marketing consultant.

There are any number of reasons you might opt to pair with marketing strategy consulting firms:

Create a Plan

You need a plan that’s in line with your overall business goals. Many times, businesses will advertise without any clear strategy, which won’t optimize the return on an investment.

Employing the help of a top marketing consultant gives you a tactical foundation on which to build your public relations and advertising.

Save Valuable Time

If you’re running a small business, you may not have time to dedicate to marketing. It can be difficult to focus on marketing at all when you’re wearing so many other hats in your business.

In these instances, the help of one of the best marketing strategy consulting firms allows marketing consultants to step in and take the reins.

Innovative Techniques

Marketing consultants have a strong grasp on the trends, technology, and innovation needed to develop a successful strategy. As a result, marketing consultants may introduce you to new software, new industry trends, or new ideas.

Expert Strategies

One of the biggest problems businesses face in marketing is their desire to do everything at one time while not doing any of it that well. Marketing consultants can show you how to narrow your efforts but maximize the impact.

For example, maybe your strategy includes trying to use every social media channel. A marketing consultant could provide you with expert data and research that will show you how to limit your social media marketing to perhaps just two or three platforms, saving you time and money while creating a greater impact. 

Improved Focus

Perhaps you have a strategy in place, but it isn’t working. Marketing is a rapidly evolving landscape; businesses that find their current strategy just isn’t getting the job done may feel it’s time to change strategies. That’s a very good time to partner with a marketing consulting firm.
