It's just good diversification.
Both can be great ways to monetize your site, they just serve slightly different segments.
The Amazon Associates program tends to work well on product based sites. While Google Adsense tends to work well with information based sites.
However, the reality is that the topic of many niche sites can be a blend of both information and product based information.
So what should you use, Amazon or Adsense?
The answer is that you can use both if you want to. I have been asked several times by people wondering: “Can I have Amazon and Adsense on my sites?” Yes, yes you can.
There's nothing in either the Google Adsense policies or Amazon's TOS that you can't use both on the same site.
In fact it's good diversification.
You get money from affiliate sales of actual products made through the Amazon links. Then you get paid for Google AdSense ads that are clicked on. Or occasionally even just for the page vies.
You can see sites that use both methods are all over the web. In particular, if you want to see it in action visit Hubpages.com. Lots of different “hubs” have both Amazon and Adsense placed on them (along with eBay affiliate links and others).
You can use this to boost your site's income and help your site's asset value.
Diversified sites are safer, tend to earn more, and tend to sell for more. If you're ever planning on selling your site, I recommend diversifying early so your future buyer feels more secure buying the site.
When they feel more secure, they're willing to pay you more 🙂
How To Implement Amazon and Adsense
Here are some guidelines of how I would recommend implementing the 2 ad networks if you decide to try this out. First, Amazon tends to work better as text links within your content rather than banner ads.
So, don't put a big 300×250 Amazon Associates banner ad in your content. It's typically less effective.
And it just doesn't look that great.
Instead, link the text within your content to Amazon any time you mention the product or product related phrases.
Also have a call to action near the end asking the reader to read more about the product, or check out the pricing of the product, or any other call to action that will encourage them to click on the link and view the product in Amazon.
Google Adsense on the other hand does work well as Ad units. I have discussed a few times in the past some of the best Google Adsense ad placements here.
In general, the ads that are in the content and above the fold will perform the best. I usually recommend a medium or large rectangle unit just below the title either right or left justified.
This is going to be your highest click through rate for your text ads most of the time.
I recommend using Amazon on your “buying intent” keywords. These are keywords with words like “best” or “review.”
Amazon can help you convert these visitors into buyers at a much higher earnings per thousand visitors than ads.
And then to become the authority in your niche, I recommend that you publish a bunch of informational content as well. “How to” guides, questions, etc.
A blend of content gives you the best chance of making the most money. Whether through Google's Adsense, alternatives like Ezoic, Amazon affiliate links, or any other type of ad.
How To Increase Earnings With Amazon & Adsense
You will need to monitor your earnings to make sure that adding Amazon or Adsense does not decrease your overall revenue. If having Amazon on your site takes away more from your Adsense earnings than it adds, then don't do it.
But the more likely problem is that ads will take away from your Amazon earnings.
I had this problem on my Niche Site Project 4. I put so many ads on page that my buying intent content wasn't converting as well.
Obviously, you will need to test and monitor your earnings over a few months to determine what works best.
In addition, you should always be willing to test out different layouts to see what gives you the highest click through rate and earnings.
If you don't want to spend a bunch of time testing your layouts, I recommend an ad network called Ezoic. Ezoic runs a continual split test on your site to help you earn more from your ads. I got my earnings up to $17.05 per thousands visitors at one point (a HUGE number)!Try Ezoic and boost your ad revenue.
This is how you can increase your earnings. I've personally found that for the most part, its niche specific as mentioned before. Some keywords will just earn more with Adsense and some may perform better with Amazon.
Overall, there is no reason why you can have both Google Adsense and Amazon on your site at the same time. You may find that it increases your overall earnings, so test it out!
What are you thoughts? Have you tested using both ad networks on your sites before?
I'd be interested in hearing your experience.
