Why do my dating sites get indexed on Yahoo not Google

[jennypretty]

Hello,

Two years ago, my dating sites got indexed and traffic more on Google. However, my dating websites got more indexed on Yahoo, but not on Google.

I learned from this forum about this method. I have been using the same strategy by adding new articles to my sites and linking some keywords to it.

For example: when I write a 500 words article and post it to my site blog, I usually make 3 links to promote my sites. I write an article every 2 or 3 weeks. I use keywords such as "black dating" or "black singles", etc.

At the same time, I write a different article and post it to Ezine or other article directories, every 2 or 3 weeks.

Can anyone please tell me what is wrong with my strategy?

Thanks.
