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.
Research your competitors, and get a link from the top 100 sites that link to them.
Search Google for your keywords, and do your best to secure links from those sites in the top 100 for your keywords.
Get links from your competitors!
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.
Don't do this all at once! Make a note of all the sites you would like to get a link from, and slowly acquire links over an extended amount of time. There is no set time period, but try to spread it over at least a 6 month period.
Searching for SEO
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).
Obviously, the higher a site ranks for the keyword, the better it is to get a link from them. And if you can somehow pull it off, getting a link from their page, the one that's ranking well on Google for that keyword, would be priceless.
Get a link from competitors
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!
