As we briefly mentioned above, your website or blog posts should target your audience (your prospects, your readers). You should be writing to them. You should be asking yourself what your target audience is searching for on Google. Based on that, you should provide the solutions to their inquiries in the form of content that is coherent with their search terms. In other words, the keywords or key phrases you use within your content must coincide with what your audience is actively searching.
Once you have the piece of content you want to repurpose and the keywords you’re optimizing for, Google it. Type in the keywords and hit enter. Then, compare your content to the content that’s front and center on page one. What are they talking about that you’re not? Are there any topics you need to add? Is the content even relevant to what you’re trying to say? Based on the content, what can you assume the user’s intent is with that particular keyword?
Pumpkin Hacking – This is a term that I came across (thank you Peter Da Vanzo) that seems to describe exactly what we did to continue to grow our traffic by double and even triple digits, month after month. The core concept is simple; focus resources on building what works. What this meant for us was paying attention to the search verticals and content that received the most traffic, most comments, most social shares, and being quick to cut the cord on traffic that didn’t perform.

Traffic data is a great way to take the temperature of your website and marketing initiatives. When you are writing and promoting blog content on a regular basis, you can use traffic data to track results and correlate these efforts to actual ROI. Be sure to look at traffic numbers over long-term intervals to see trends and report on improvement over time.  
What I’m getting at is using Google’s related searches to your advantage. Google related search queries are exactly what they sound like—searches that Google has algorithmically associated with certain groups of keywords. So, if you find a keyword that has high volume, is relevant to your target audience and business goals, and has relatively low competition, your job isn’t done. Instead, make sure that you’re taking note of related searches to ensure your content is in-depth and fully addresses the topic.
If you check out some of the suggestions below this though, you're likely to find some opportunities. You can also plug in a few variations of the question to find some search volume; for example, I could search for "cup of java" instead of "what is the meaning of a cup of java" and I'll get a number of keyword opportunities that I can align to the question.

Monster-Traffic is another traffic exchange, though it’s initially a little off-putting due to the 1995-style website. It’s a free for all styled advertising list, where anyone signing up becomes part of the audience and an advertiser at the same time. You sign up and you can enter a link into their system, and that link is added to a roster that is send out to every member of the group. Additionally, registration allows a free solo ad; an ad that isn’t drowned out by other advertisers in that mailer.
