Social media is best way to promote the product because today's world is much active on social media and people can like, dislike and give review on the product.
Social media is a platform where one can easily know the likes, coming trend according to which it becomes easy for the business to do production and enhance its promotion.
It is a type of mass media communication where at a time we can contact lots of customers with little time and effort.
Products are for society and it is important to reach customers for providing products and social media word itself means a society's media, so.
Using social media to advertise is not the greatest of ideas and often recives bad feedback. I can tell you as a blurter, that users advertising on their accounts is extremely unwelcome and is treated with utmost disrespect.
BUT.
If you want ads on social media websites, that is NOT out of the question. Bubble ads on the sides of the windows are often regarded, ocaisonally with interest. Companies like Google Ads, and Adsense (Are they the same now?) can put ads on websites like that for you.
BUT. AGAIN,
However, the way you asked this question did NOT sound like you were intrested in advertising through social media, but you were some young jerk- I-I mean, child, trying to get other losers- I-I mean, people, to answer an essay question. If thats the case, then write about how it ISN'T the best way.
