Apart from search engines and email marketing, the top source of traffic is SMO. If done in an effective way, you can expect huge traffic on your website.
As you know, a big number of people use social networking websites, forums, and online communities; SMO helps you to increase website visibility.
Now a day, companies provide their customers a business channel (apart from traditional email and call support) such as Facebook page, so that the customers can easily reach them and they can have a great connection.
Social media platforms are being proven as a great source of advertisement.
Ease of target: With social media platforms and online communities, you can even advertise to a limited audience. Or, if your business covers the worldwide audience, then it becomes much easier to reach the global audience with SMO services.
