What the heck is SEO
Short explication :)
Search engine optimization (SEO) is one of the most cost-effective ways to get traffic to any website. It’s one of the first things that most affiliates learn, so we won’t go into it in depth here. But it’s such an important subject that it deserves to be revisited from time to time.
SEO is an ongoing process. It’s not one of those “set it and forget it” things. Once you’ve done your initial optimization it becomes easier to maintain it, but you must keep working at it. Search engines change their algorithms frequently, so it’s crucial to continually check on your rankings. That way, if they drop, you can take action before you lose too much traffic.
If your site ranks highly in the search engines, you won’t need to spend a lot of money on pay per click and other forms of advertising. You can concentrate your efforts on building incoming links and creating new content to keep your visitors happy.
