Hi Rahul,
As I working in Mumbai-based Web Development & Digital Marketing Company & through whatever knowledge I gain social media marketing is all about creating awareness about your product & services. Social media is a great medium to reach out to your audience.
But while doing these you will have to focus on some important points
1. Gather information about your product
2. Identyfy your audience
3. Target relative audience
4. create some case studies
Social media platforms have huge & crazy active audiences that allow you to promote your services beyond country boundaries. Therefore you will have to implement your strategies very carefully. People on Facebook or Instagram could prefer to use these platforms to make friends & read out stories of others, they are not intent buyers.
so we need to create some stories that reflect your product or services through which we can manipulate or relate with that story we target them emotionally & technically.
These are some other platforms you can use for marketing:
Instagram
Twitter
Pinterest
Linkedin
YouTube
All the above have their nuts & bolts which we need to fit very carefully at social media.
