I have registered one domain name which was 500000 times searched keyword in one month. But this site is still under construction. The keyword is "consolidation Loan Program Student" and domain name is consolidationloanprogramstudent.org. How far i will be able to optimize my site on this keyword? How much time it will take to be on first page of google search using the same keyword as domain name? Thanks in advance guys..
Yes, do standard on-page optimization but you will have to work on getting lots of quality backlinks to compete and bump existing sites off page one.
I think you misunderstood overture results. One thing about overture is that it never gives results on sequence. Like for "webmaster forum" and "forum webmaster" the results will be same. I searched for "student loan consolidation program" and it gave me 438960 searches in overture. And also in Google, 607,000 results for "student loan consolidation program" and 30,600 results for "consolidation Loan Program Student". So I think the right word is "student loan consolidation program". Correct me if I am wrong.
