Depends who you are affiliated to.
For example Amazon will give you text links, Ad links and also Codes which you insert into your Articles or on your SideBar.

For straight forward Affiliate links you simply highlight a piece of relevant text then click on the Paperclip icon in the little menu.
A box will appear directly underneath that highlighted text and you insert your affiliate link.
You then click on the little cog wheel to the right of the box.
Next Screen - make sure the open in new tab box is ticked then click on Add to page/site

You should see your link has turned blue.
Save/update and click Preview and test the link.

If it takes you to where its supposed to then job done.

Hope you follow and if not get in touch.
Not right now though coz I have to get off home.

in the training, there are whole sections talking about placement and content. The quick answer to your question is yes. Put links in your content if the content pertains to the product. I only promote three products so they are always on my sidebar widget and they are static but there are widgets that will rotate products based on tags, categories and the like.
