Greetings!
Experience and training with any job goes hand and hand.
Without the training and self education, an individual wouldn't be able to move forward and excel in anything they wish to pursue.
SEO is vital to your online ventures, especially if you choose to have a world wide audience. With basic SEO, you need to get knowledge on:
How to blog. Getting use to WordPress, uploading images, type of niche, content, etc.
Research the importance of tags, categories, keywords, etc.
Methods of advertising your online business/product
Simple coding of HTML and BBCode.
Once you educate yourself on these aspects to the point where you are comfortable, you can further expand on understanding SEO, Traffic, backlinking, etc. in much more detail. But in order to get to this stage, you have to feel comfortable before moving into a more elaborate territory
