Your domain is richestwomen.info

1. There is really nothing on google for the .com version of that name "richestwomen". 5 pages with no descriptions with the urls.
2. There is no site with the .net version of that name "richestwomen"

I see this as a no-brainer that you would be near the top having the domain of the same search phrase in the title and any other repetitive places in the page you have placed it.

I'm not sure you have enough Google ads on your page though LOL
