Hey Brankica! Awesome contest entry! Love it. I, like you, get a decent amount of traffic from Ezine Articles, too! I am not in a rush to do anything drastic just because of the algorithm change. Hubpages is also a lot of fun and I am pretty close to finally making my $100 payout from Adwords. My hubs have been viewed over 10,000 times and I've had a lot of fun there.
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.  
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.
How often should you go evaluate posts on your business blog? If you post multiple times a week, checking once every three months is a good rule of thumb. If you post only a few times a month, evaluating twice a year should do the trick. Remember, search engine algorithms evolve and change – and so will your keyword rankings, so set a calendar reminder for yourself or your online marketing manager to dig deeply into your search traffic and keyword rankings so you know exactly where you stand and where your biggest opportunities lie.

Direct traffic is defined as visits with no referring website. When a visitor follows a link from one website to another, the site of origin is considered the referrer. These sites can be search engines, social media, blogs, or other websites that have links to other websites. Direct traffic categorizes visits that do not come from a referring URL.
