What makes internet marketing so effective is that it doesn't have to cost a huge amount to be successful. You can spend an awful lot of SEO and content marketing and thereby try to get your site to the top of Google, but sometimes it just takes one smartly placed link to drive huge amounts of traffic to your site. And if you're willing to put in consistent time and effort, then anyone can build a massive, loyal audience thereby become a big influencer in their niche. Thus, internet marketing is the 'great equalizer'. Marketing no longer requires a huge budget: it is now something that you can do just as well as the largest organizations – as long as you're smart with it.
Internet marketing has other advantages too: it allows you to actually engage with your audience for instance.
Using social media or running contests means that you're able to interact with the very customers you're trying to obtain and get feedback from them.
Then there's the simple fact that the web is capable of reaching such a huge audience – including people from all around the world.
If you're selling something with international shipping, then this is by far the best way to reach a global audience.
Internet marketing is an answer for all of those required!
