Carlos,
I believe I found your answer. (The links I am about to include are NOT affiliate links, there will be no commission if you join or not) You mentioned you have 3 domains, are they similar, covering the same industry? if so, it might be interesting to focus your time and seo efforts into 1 domain and redirect the other 2 the the main of your choosing.

If the domains are totally different and cover different industries with different demographics, I would have 3 different websites, after all the products offered should be different.

You also mentioned templates… FlexOffers has a great tool for you. it is called Custom Affiliate Templates and you can manage the design to match perfectly with your design or if you wish you can also simply add the templates to a parked domain. Here is 1 example:

http://uber-deals.net/

Note how the design fits perfectly and each page has it's own URL, title tags (good for SEO)

It is free to join and below is a link to a page with the full details and even screen shots of a few of the templates available. Good luck

Hey,

One of my examples: http://www.makemoneycb.com

It's about making money online with clickbank. You can try different approaches, either promote many products from a single domain, or just one. I promote one product from one domain targeting one keyword and it works well for me!

Thanks!!

Please stay with me because I have a proposal for you that will make a super affiliate with a six figure income out of you if you start right.

I think that you are moving in the right direction. In this day and age you don't need to reinvent the wheel. You can't make money online with affiliate programs if you do things the same way they were done 2 or more years ago.

In affiliate marketing you need to achieve more with less. You need to run your affiliate programs without sacrificing time with family and friends.

However you can get more than you bargained for which will enable you to hit the ground running and spend fewer hours in front of your computer whilst fattening your bank balance.

Consider this:

1.You get templates more than you're going to need.

2. You get easy to use software to build websites.

3. Video tutorials on how to do everything including how to drive traffic to your websites.

4. Of course I'll show you examples of websites to see.

5. Above is what you're asking for but there's more to it:

Now here is an interesting money making plan for you:

1. A free turn-key Website worth $2,097 plus Website Installation worth $300 and Automated Product Fulfillment.

That's without paying a dime. If you opt to pay for the hosting of your website you get up-scaled benefits.

2. You get the Money Making Package which entails providing your own Domain Name, one that is keyword rich.

3. You get to build your own landing pages for your affiliate programs or even websites. The Package includes CPanel.

4. Video tutorials on traffic generation techniques across the whole spectrum.

5. Whilst building your own website if you choose to do so you can monetize ready made pages of well researched product review pages with high conversion rates.

It doesn't get better than this. This offer provides you with the opportunity by making available all the tools, video tutorials and resources to design and succeed with your own business model of well suited affiliate programs.
