Let’s say that you want to move your blog from a subdirectory URL (yourwebsiterulz.com/blog) to a subdomain (blog.yourwebsiterulz.com). Although Matt Cutts, former Google engineer, said that “they are roughly equivalent and you should basically go with whichever one is easier for you in terms of configuration, your CMSs, all that sort of stuff”, it seems that things are a bit more complicated than that. 
The first step that I take is to do a quick Google search to find pages on my domain where I've mentioned the keyword in question so that I can add an internal link. To do this, I'll use the following search query, replacing DOMAIN with your domain name (e.g. matthewbarby.com) and KEYWORD with the keyword you're targeting (e.g. "social media strategy"):
Note: Google made a change a few years ago to how they track keywords and it has had a big impact on the discovery process. Before the change, Google would show which keywords consumers were using to find your website, making it easy to understand where and how your website was ranking. Google changed their tracking system so that any users who are logged into a Google account while searching will no longer have their keywords tracked as their Google activity remains encrypted. Due to this, when looking at Organic Traffic reports you will see (not provided) as a keyword throughout the reports – this often makes up over 90% of organic traffic and requires us to dig a bit more creatively to find what we need.
Are you currently excluding all known bots and spiders in Google Analytics? If not, you may be experiencing inflated traffic metrics and not even know it. Typically, bots enter through the home page and cascade down throughout your site navigation, mimicking real user behavior. One telltale sign of bot traffic is a highly trafficked page with a high bounce rate, low conversions and a low average time on page.
The term “organic traffic” is used for referring to the visitors that land on your website as a result of unpaid (“organic”) search results. Organic traffic is the opposite of paid traffic, which defines the visits generated by paid ads. Visitors who are considered organic find your website after using a search engine like Google or Bing, so they are not “referred” by any other website.
