The success of any commercial website depends on traffic and conversion. And we all know that those 2 factors go hand in hand. The better, more focused the traffic is, the more conversions you will get. And there is no better traffic than Organic Traffic coming in from keywords that fit the content of your website.
It’s really easy to understand why Organic Traffic is the best – One, because it’s FREE targeted traffic and Two, it’s quality incoming traffic and leads directly to what you’re offering and because of that, the conversion rates are the highest. But getting Organic Traffic is either very expensive (Pay Per Click / AdWords, etc.) or very costly (time and money) if you plan on doing it by optimizing and expanding the content of your website.
The very basic principles of Search Engine Optimization (SEO) are On-Site SEO (content and tech used on the web hosting and website) and Off-Site SEO (building links and a social media presence). On-Site SEO is typically very costly and difficult so is done not very often, but Off-Site SEO or link building is something that is easy, inexpensive, and can be refreshed when a boost is needed.
