we r workin on a site(5digit competition only one keyword with 6 digit competetion) for 20 days now tat site s in 3rd n 4th page for all keywords n wat to do get our site in 1st page within 7 days???
start blog posting with quality content, also do article submission in best article directories, you will get fast result from that.
need lots of backlinks. It takes time to hit page one if you do it correctly using white hat techniques.
Participate in forums, do social bookmarking and Updates regular in facebook and twitter. (Avoid SPAM)
First of all that's not sure your result will be come up with 7 days only. But for getting good improvement you can start taking links from live website means Link exchange and do do follow social bookmarking. if not then go to seo-first-page(dot)com.
I dont think that anyone can gaurantee you to bring the keyword on top within 7 days. Just follow Google guidelines and good link building can bring your site on top.
I don't think that it's possible to hit 1st position in 7 days if you are fighting for high competitive keyword. Bringing your site to the top is a very long story!
What is believe is you are aiming for something very big and that too in very few days... Your keyword sounds quite competitive to me... Get 1st page rank and that too in 7 days seems something very difficult.
