One of the most common mistakes that people make is to build a website and expect it to get visitors without any effort. This is a huge mistake, but a mistake that is made by thousands of people who start a website in hopes to increase their exposure, only to see that no one is coming in and they are not getting any results.
The way to solve this problem is to learn to promote your website. The best way to do this is to create content quite often and to learn about the best keywords in your niche. This is a basic action you need to consider if you want to be seen. Keep in mind that thousands of competitors are working hard to be noticed.
