What are the best strategies to stand out on social media as a brand?

1- One post every day.

2- Stroy to tell 

3- genuin content 

4- catchy design 

5- intergrate with commentors and likers.

in my very humble openion 

Do something other similar brands don't; this makes your brand stand out for the different strategy alone. Engage with your community on a unique level so that you appear like a living, breathing entity rather than a soul-less machine run by empty suits.Post something interesting that your audience might want to read. For example, if I was a company making laptops I would make posts about who uses my product and for what; like I would make note of a police officer using my product for his work.This makes the brand a part of a community rather than a showpiece on a storefront not meant to be used.

Be socially responsible, engage in society & with people to show them care & ownership!

Communities (or customers) play a vital role in addition to the product or service quality & branding popularity.

I would add among the previous answers:

1) Create unique, humorous, honestly content

2) Ask questions to your audience

3) Answer your audience's comments, answers

4) Create a humorous, detailed video of your product

5) Regural posts on your social networks

Just always keep on the trend and create a strategy that is currently in demand to market.

Competitive and Innovation

The key is to make something different. In other word, you have to provide some specifies in your products such as: high quality, different design, attractive packaging,... Moreover, you have to find the suitable communication technique to advertise your products.

Introduce work culture and client testimonials throughout the web and trend success stories of both bussiness products and customers. Product detailing and its beneficient factors must be the key features for promotional activities.
