Content marketing is important for the basics of driving traffic to your website and offers, and for converting that traffic to subscribers and customers.
Content marketing is a personal thing. Much more personal than, for example, Pay Per Clicks ads, or ads on sites. These last two are simply advertising. Your content marketing communicates with potential visitors and buyers. With consistent content marketing you should get more targeted traffic who also respond more.
Of course, it takes more time and effort than putting up an ad, which is why still not all that many people follow through in doing it. You might also have worries about the search engine rules about content. However, if you only create simplistic content with no value in your niche, then you might not be ranked anywhere on the search engines and/or get no response from people in your niche.
Create valuable content and place it on sites where your target market is online regularly. Place valuable content on your website making sure it’s unique to your site.
