The best online traffic is targeted traffic. Actually, that is the only kind of traffic that you need. Sending a lot of visitors to your site that are untargeted (which means they couldn't care less about what you are selling) would be a big waste of your money and time.
To make sure that you only drive the most targeted online visitors, you need to decide just what would make a targeted visitor. Who are you really trying to attract? Make sure that you focus on those people who are passionate about your product or service and are ready to buy.
To get the best online traffic when you are first getting started, don't bother paying for it, rely on free traffic sources.
That is one of the biggest mistakes many people make when they are just starting out. The truth is that paid traffic sources usually have a pretty steep learning curve and you will almost always spend a lot more than you will make.
Why put yourself in such a stressful situation when you can get the best online traffic for free? Start with free methods and as soon as you are profitable and making some consistent income you can then learn how to use the paid methods,that way you don't have to fret over how much you are spending while you are learning.
The top 3 methods for free online traffic are:
1. Article Marketing. Write a quality, keyword rich (keyword rich, not keyword stuffed) article that provides some real helpful information and submit it to an article directory. You will be able to include a bio or authors box at the end of your article that will include a link to your website.
You know that anyone who takes the time to read the whole article will be truly interested in the subject which means they will be targeted visitors.
2. Make frequent, and helpful, forum posts. This will benefit you in two ways: for one, you can set yourself up as an expert in your field and build credibility, and two,you can get people from the forum to visit your website by providing a link in the forum signature at the end of the post.
3. Using Twitter and Facebook, as well as other social media sites. Again, you have to do it the right way. If you just send out a bunch of spammy sales pitch type tweets you won't get very far. But if you offer all your followers some helpful tips that can make their lives easier and help them accomplish their goals you will build trust and they will visit your site.
I know that there are some excellent ways of generating traffic online, but for anyone with a limited budget and limited knowledge, the best online traffic is free targeted traffic. Learn to do that first, than you can build from there.
