It’s important to thoroughly check the product, service or company you are promoting.

Here’s some names you might be familiar with that are in Google’s bad books:

Specifically what Google doesn’t like include:

* Data collection sites that offer free items, etc., in order to collect private information
* Arbitrage sites without relevant and original content that are designed for the purpose of showing ads
* Affiliate sites without relevant and original content that are designed to drive traffic to another site with a different domain
* “Get-rich quick” sites
* Malware sites that install software on a visitor’s computer
* Poor comparison shopping or travel sites whose primary purpose is to send users to other shopping/travel comparison sites, rather than to provide useful content or additional search functionality

In addition to this it is important that all internet marketers promoting their own products or products of others in the United States become familiar with the FTC’s guidelines for advertising.

In short Google and the FTC are making us internet marketers aware of our responsibilities, whether you like it or not, and ensure that any products or services you promote don’t infringe trademarks or copyrights, are not scams, and will not provide your website visitors with a poor or harmful user experience. That means do your due diligence first and check out any company and their products or services before you decide to promote them to others.

Hope this helps and let me know if you have any other information to add to this.

The domains cover some broad markets inclucing money/finance, fashion, education, food and property. This is in addition to similar purpose sites or blogs we have for travel, health, dating and entertainment.

Having fun setting them up. Importing WordPress themes, redesigning them, setting up the category structure, and so on. Some very nice and very practical and easy to use themes are available now. And the best thing is that they are all free. I just need to provide a good web host and WordPress does the rest.

Future sites that we need for promotions will cover markets like electronics (cameras, video, GPS etc).

To make our new domains SEO friendly as possible I decided that they are dot coms, not previuosly banned by Google or Yahoo. I also checked the webarchives to see if they had any prior history. If they did, a real website got a pass. But if the domain had been used for a spammy looking site I avoided it. Just in case.
