Hi, You can achieve ranking in three to six months in google and other search engines.
You need to do some tasks in three months
1) Social bookmarking
2) Social media posting
3) Forum posts
4) Blog commenting
5) Blog posting
6) add posting
But, When you will start your off page seo, you need to check first on page seo that your title and description has keywords you want to rank or not if yes then go ahead and if not then add them.
