I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
It’s becoming increasingly important for businesses to have a presence on social media. If you have a knack for using social media platforms such as Facebook and Instagram, you could make a living helping businesses reach out, engage and promote their product through social media marketing. Social media managers or specialists also can earn money through training and consulting.
If you have built up an email list, you could also promote your affiliate offers via email promotions. Just make sure you build up a relationship with your audience first instead of going for the hard sell straightaway. The emails you send out must contain your affiliate links to products so when your audience click through. the sale is attributed to you.

This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.
