Ad words is not marketing. It is just the beginning..

Web marketing includes SEO, SMM, ads, facebook marketing, twitter marketing, youtube, limkedin..etc. besides, it is more important to get engaged to people.

Interaction in blogs, forums , discussions..

You may also think of having sales people to work with you, do some tele marketing, have promotion codes..

Depending in your target market, you may need to have printed ads on magazines, flyers, newspapers..etc or even radio or tv ads...

You need to know where your customers and go to them.. Either online or offline..

Besides, you need to work on branding and also on showing how differentiated you are from the comparatives. Or if no comparatives, then show you have a solution that doesnlt exist.

The 200 leads you reached, you need to talk to them and have their feedback.. Give them trials ..etc.

Most people think they will make a million $ sales after making the MVP which doesnt happen. The effort you need to do on marketing and sales is even more than what you did till you reached your MVP.

For a 10$ thing, you need at least to reach 20000 leads , before thinking of takin anything down. Coz till now, you dodnt reach your customers.

It is time to start :)

I'll be there to help...
Good Luck!!!!
