Adding an affiliated link
To do so, you need to go to your WA website. Click the black airplane and choose links and banners. Here you will find your affiliated links and banners.
1. For the links
Just copy them and paste them to your liking. Best is to highlight a word in your text and to link that to your affiliated site.
How do you do that?
In the editor of your wordpressite click the link button and, in case you did not do that yet, also activate your full taskbar.
2. For banners
Choose your format. Copy and paste them at your liking (before or after a post) If you want your banner to appear on all your posts and pages, best is to use widgets.
Go to dashboard>appearance>widgets
Add the html box to your sitebar or footer and paste your code.
Done.
Easy no?
Now that you know how to add a widget to your sidebar or footer, you can Experiment with the other widgets. Always view your result.
