In this new technological world, businesses have had to find new ways to advertise their products. The old way of catalogs and newspaper announcements is out and digital marketing is in. In a society ruled by millennials, online is the way to go. If you're not sure about making the switch, check out the information below to help you make that decision:

1. Most people are on social media
There's a good chance that the next person you run into has an account on at least one social networking site. People use them to post pictures, talk with friends and share their thoughts. These sites, however, have evolved past mere peer-to-peer communications. Businesses can now create pages to advertise their products and services. While you shouldn't be active on all social media sites, you should try to create a presence on a few, AJ Agrawal, founder and CEO of Alumnify, said in Inc. If you're posting consistently, you will drive customers to your page to check out what you're offering.

2. It's inexpensive
Creating a business page on social media comes at no cost to you. You'll be able to communicate with followers for free, and it's easy enough to do. There are add-ons that you'll have to pay for, such as promoted pages and posts and ad clicks, but they're not necessary to have a successful account. If you do decide to pay, at least on Facebook, you can create a budget for your marketing plan. Advertising on social sites is cheap compared to pay-per-click marketing, Stephan Aarstol, founder and CEO of Tower Paddle Boards, explained in Inc. Digital promotions won't put a huge dent in your financial plan, so it's worth looking into.

3. Go mobile
These days it's not hard to find someone with a tablet. It's even easier to find people with cell phones. If you're going to go into digital marketing, you should also make sure your content is mobile friendly. Smartphones and tablets make up 30 percent of video consumption, Ted Dhanik co-founder of integrated-media advertising company engage:BDR explained to Entrepreneur. Mobile advertisements provide an easy and convenient way for consumers to find out about your product. Whenever people have a free moment, they're looking down at their devices, so why not make sure they're seeing your company.

Digital marketing may seem unnecessary or intimidating, but if you know your product and audience well, you'll be able to do it successfully.
