From the Ancestry Blog:

We have recently become aware of three websites purporting to allow family history research: SearchYourGenealogy.com, Ancestry-search.com and Australian-Ancestry.com. The sites claim to have “the largest online genealogical search tool” and promote themselves as the foremost resources for genealogy, but from what we can tell, these sites are nothing more than a series of web pages with links to other services. These sites, in our opinion, are clearly fraudulent.

On each site, potential customers are lured to purchase under what we feel to be false, misleading and deceitful promotional material, and get little or no value out of money spent at the websites. Blog and message board posts from the community confirm this opinion.

The people/companies behind the websites are buying very high level paid search results on Google and other sites. In addition, they are using trademarks of well-known websites, including Ancestry.com and Genealogy.com, to get higher-than-normal natural search results. It appears the site colors, fonts, and pictures on at least one site are designed to mislead people into believing the site is related to Ancestry.com.
