Great question, sameergupta12! Almost everyone has a mobile device, and many spend a lot of time shopping for goods or services using their mobile devices. So it is imperative that any small business has their website “mobile-optimized.”. While an absolute MUST for any small business that sells online, it is equally important for service businesses as well. If your website is not mobile friendly, takes too long to load or has other issues, your potential customer will most likely move on to another business.

The posters question was about Mobile SEO, not Mobile Optimization - two different things. SEO is Search Engine Optimization to get your website to the top of the search engine results. Mobile optimization is making your website easy to navigate on a smartphone.
As far as why mobile SEO is important, it's as I stated; to get your website to show up at the top of the search engine results, which may or may not be worth your investment, depending on the type of business you have.
Hope that helps.
If possible make mobile application and do seo in play store. that will give you more client.
