What are you after, traffic or rankings? The effort for both can be different. You can get traffic instantly through PPC or CPM ads but it sounds like that's not what you're after. The only way to rank your site is with doing proper SEO. Do onpage optimization (title/meta tags, h1, LSI keywords, bold/italicize keywords, good linking structure, sitemap, siloing) and of course off page optimization (backlinks, backlinks, backlinks...in best case high-quality, "dofollow", high-PR backlinks). But you won't get rankings in 2-3 days, unless your niche has really low competition (and even then you could become victim to the google dance).
There is no any way which can have this function, but you can pay the ads in google for the up of keywords, it will be the first choose.
I think the best idea is the give a ads links to high PR sites, thank you all.. but any on know the high pr sites with less cost..??
Depends upon how competitive your targeted keywords are. If you target less competitive long tail keyword you don't have to wait for 2 or 3 days, within 24 hours your site/blog will be on top of search engine.
What you really want is merely impossible to achieve..getting PR is not like getting a money in an ATM wherein you can directly get it. It takes a lot of time, effort, and energy in doing it. There are some tools that can help you like SEO tools including Back links, Directory Submission, Social Bookmarking, and Pinging..But, definitely, it can't make your keyword as quick as what you want. Even if you will buy several softwares, it can never happen.
Use traffic travis SEO software. It generates keywords. It will get you on first page of google. And also SEO powersuite link assistant's software. Guaranteed results.
I am not promising you to rank your keyword in SERP's in 2 or 3 days, but I can suggest you a very effective way that will surely help in your keyword ranking i.e. social bookmarking. There are a lots of methods you can try for your keyword but this one will definitely helps you. If possible try to use do follow bookmarking sites. This will rank your keyword on Google search page as well as increase traffic for your site. Try to do it with quality, not with quantity. Good Luck!
Google love Optimization in a organize way like Blogging or Blog Linking, Smart Linking etc.. You can think for good backlinks specially Blog-links against your main keywords, its really work.
