Hi Ted (or should I call you “awesome”? ,
Check out the list of article directories here:
Your main focus should be on creating content that your audience will find really interesting – if this is the case, they will want to click on your link and check out your site (or better still, share your article (and your link)).
It’s not good practice to go mad plastering links all through your content – for sites such as ezinearticles.com, a simple credit to the author and link at the bottom of the article can be sufficient.
I can’t stress how important it is to keep your content well written and interesting to your target audience – without this, nobody will bother checking out what you have to say on your website.
Remember also not to send your articles to all (or as many as you can) of the directories at the same time – just make sure you do it consistently (it looks more natural to the search engines this way).
There are quite a few aspects to copywriting in regards to SEO, but might be a bit heavy at this stage.
