Try searching again, use the incognito chrome browser which removes your personalized search factors. You will see that in your first example, Bytemaster's blog on the bitshares.org page appears as the 17th search result. Your second example, bitshares.org is the fifth search result on the page. My site Bitsharesblog.com appears in the thirties of the search result for both of those search phrases.
