Technically, if we look at the raw data, we are still going up. If you look at this graph, the blue line represents the # of times we are shown as a search result in Google. The red line is the number of time people click on those search results. The red line has been showing improvement as well, though hard to see because it doesn't scale well with impressions.
As you can see, Google gave us traffic, and then stopped the increase for 2 weeks. After two weeks, they have again added more impressions.
I believe that this is Google's system's way of testing us. They give us a bit of traffic relevant to a search term, and then look at how successful that link is through time. My theory is that after 2 weeks, the website is still going strong, so Google decides to give us a small promotion higher in the search results.
As long as this blue bar continues to rise, we will continue to get an increase in Google traffic. Search only currently gives us 4% of our current total traffic. This is up from 1.6% a couple months ago. Let me show you the potential that it COULD someday become by showing you Sociopath World's impressions data.
