If you want to rank well for a specific keyword, especially a competitive keyword, you can go about it the old-fashioned way and try to get links from anyone you can and slowly move up the rankings ladder. Or, you can use these high-powered techniques to quickly gain authority in the eyes of Google.
Copy your competitors
When you do a search for your rival's website, competitor.com, you'll find out the most authoritative sites that mention your competitor. Visit these sites and decide if it would be possible for you to get a link from those site's. If it's a review site, it may be as easy as sending a free product for review to the owner. If it's a forum or wiki, it may be just as easy as adding your link.
Often, the best way of finding a solid place to get links from is as simple as going over to Google and typing in your exact keyword. You may think this is crazy and that there's no way you'd be able to get a link from someone who is ranking well for your desired keyword, but you'd be surprised just how many website owners care nothing for SEO and will be more than happy to link to your site (as long as your site is valuable to their visitors).
Get a link from a competitor using your nicest greeting and biggest smile! Many competitors will be up for a link exchange, but if you have some unique pieces of content that your competitors don't, you may be able to get one of those precious one-way links!
