Hi, I need to reduce some of the keywords ranking in the first page in google is there any techniques please let me know.... like offshore company formation ranking in the first page URL is http://www.jumeiraconsultants.com/index.html
If you make some fake profile with using your keyword than do SEO with your targeted keyword with that link. Its Negative SEO.
Are you basically asking how to drop the rankings of a competitor? Not cool. Why not focus your efforts on ranking your own website above your competitor?
I'm in total agreement with lapseo: focus on your own SEO campaign. It obviously needs to be better if you are having problems beating your competitor. Look up an SEO basics guide (such as this one) and make sure you're covering those.
