What's a good conversion rate for advertising Amazon products?

Sometimes I get 20% conversion other times around 5-10%.

Thanks, but Empower Network spam isn't welcome in this forum, and nor are links to Empower Network squeeze pages. We've had ridiculous amounts of it, and we don't tolerate it. All is does it create work for the moderators, removing it. I appreciate that spamming Empower Network is - to some people - a natural and instinctive response to a question about Amazon conversion-rates, but that doesn't make it either a welcome or an acceptable one.

It depends whether or not you're building lists. The conversion-rates among traffic subscribed to your list is always going to be dramatically higher than from mere "site visitors", and of course there are reasons for that. (I'm not suggesting you should send Amazon affiliate-links in emails - but the people who click the Amazon affiliate-links on my sites and buy things are people who have got to those links as a result of email I've sent them. This hugely increases conversions.)

Like almost all affiliate marketing, your income from it will depend on how good you are at list-building, communicating with your subscribers, establishing credibility and trust, and the extent to which people are willing to rely on the strength of the recommendations and representations you make because it's you who are making them. However much some people like to pretend otherwise, that's just "what it's all about", really.

There are one or two (I think literally one, or maybe two) people who claim that it's possible to earn substantial four-figure monthly incomes from Amazon without list-building, but for myself, whenever I try to look at what they're doing, it always appears to me that selling "information"/"services"/"products" to beginning marketers - rather than Amazon affiliateship itself - might actually be their primary source of income.

To earn significant money from affiliate marketing, in general, you need to do three things ...

(i) Keep your potential customers returning to the sales page (because not so many people buy anthing much at their first visit to a sales page!);

(ii) Make increasing sales (ideally at progressively higher prices) to the same "captive audience" who regularly rely on and trust your recommendations;

(iii) Establish the credibility and trust necessary to do both the above by earning's people respect as a provider of niche-related information.

Without building lists, of course, you can't do any of the three and you'd just be throwing away almost all the traffic you ever generate that doesn't buy anything immediately.

For most people, most of the time, it's just about as simple as that, overall.

These three threads are more informative ...

Is it a good idea to spend some time on building a mailing list ?

Does anyone even make money online without an email list?

It completely depends on the traffic source. We cannot talk about conversion rate with just 100 clicks. Min. 5000 clicks will give realistic picture on conversion rate. It can definitely increase if you have good review and targeted product as per the niche etc
