I have this site that ranked first for "estructuras truss":
See Google Result (mail.iddeasp.com/truss-alquiler-y-venta-de-estructuras) iddea sp

I've modified this page in order to have "estructuras truss" as an exact phrase... and Google didn't even bother to rank that page.
The new page is

This page is not listed in even in the top 100 on google.
I got lucky because as I'm using Drupal ... the old page remained somehow in cache and Google still finds it...still it's cached in March and the new page I've created it a week ago, 30th of May..
Anyone know what am I doing wrong?
