SEO, List building, Guest Blogging on high authority sites, Social Media sites are one of the best and effective way to drive traffic to your site. However you have to add quality content on your site on regular basis.

It's better to start on Facebook, Twitter, Intagram or etc. But for me the best way to advertise your product is have a good quality of products because when customers like your product your costumers now become your advertiser maybe he or she advertise it to there friends, neighbors, classmates, officemates until your products became famous because you have a good quality of products.

For me make your costumers an advertiser to your product because it's free all you need to do is make a good good quality of products.

If the business is at it's starting stage then you can advertise it locally using the local medium. It can be advertising channels, mouth to mouth marketing.

As stated previously, social media is the best advertising medium as there are number of users online 24 hours. You can start posting on the pages related to your business to attract the co-related followers.

Facebook, Instagram are the best solutions. Make sure you have the best graphics and text for the online marketing.

When business will be well established then you can sign-up for the paid service of advertisement. There is pay per click charges of those services, you can sing-up to those services.

You can use the blogs for advertising. There are various professional adverting services too which will attract the genuine users.

First you should search for a buy and sell on your area or country. You can try posting your products on ebay. ALso, I would likely suggest to start on social networking sites since many internet users really spend lot of time scrolling their newsfeed on facebook, twitter, instagram and other sites. Among them, I think the most site that had the largest number of users is on facebook, and personally, I have purchase many products on facebook, some of them are just random, it just happens when a post pops up and being influenced by the comments and me ending finding myself buying the product. Also you can try on instagram because it becomes a popular site to advertise and sell your products by taking great pictures of them.
But of course it depends on the kind of product you are selling and what kind of your target customer.
