Which social media network do you prefer to promote your business?

Essentially depends on the industry and customer base of the business.

For example, a HR agency would probably need to promote themselves and their services on LinkednIn where they would be more effective compared to other platforms such as Facebook. Since LinkedIn users focus on work-related networking, it is a great platform for B2B businesses as well.

If your business is a B2C, then Facebook is probably the best platform for promoting your brand as it boasts the largest number of internet users (approx.1. billion). 

Instagram and Twitter are also good options if your consumer base exist on that platform. Snapchat is an upcomming social network that is growing exponentially and is expected to be the next best platform for geo-advertising. 

It depends on your target country and your target audience. When you put your SM communication strategy on the floor, take into consideration the penetration rate, engagement rates, and number of users of your target audience  in the most popular social networks. And when you have the numbers, you will have a clear image of which social networks you would better to select and employ for your business. 

Definately, I prefer facebook which ranked No.1 among the social media networks to promote and market products/service for business ,followed LinkedIn in second rank and my third and fourth choice would be Pinterest and instagram.  

It depends who is your target audience. Different social networks have different users by demografics, interests etc. For example if your target audience are middle class professional, Linkedin could be one of the platforms to use. If your target audience are young generation, instagram is good to use.

It is best that you identify your target market first. Your market's lifestyle and habits. If you wish to reach a broad audience, then it is best to promote more in facebook. If you are specifically targetting a niche market, then you can combine facebook with instagram and/or twitter or linked-in per se if your business is more of recruitment. But you need to also check the territory in which you are targetting as there as other famous local social media network in other countries.

Depending upon the target audience and the business industry, today a lot of social media promotion options are available. The most commonly used are Facebook, Instagram and Twitter. Targeted promotions are also possible through these sites.

Youtube- the future of the internet will be 90% video!

It depends on the type of business and the product. All social media networks provide free platforms making them a great resources for all businesses aside I would do interactive media like videos and augmnated reality ads that attracts people and pormote the brand more.
