But why have things changed?
“We make more than 500 changes to our algorithms in a typical year,” a spokesman for Google told Yahoo News. “With each of those changes, sites will shuffle to different positions in our search results. We have not manually taken action to change the ranking of the site.” As Search Engine Land notes, the shift may be related to Google’s announcement Tuesday that it has refined its algorithm to highlight “official pages.” “We’ve made an adjustment to how we detect official pages to make more accurate identifications,” Amit Singhal, Google search SVP, wrote in a blog post. “The result is that many pages that were previously misidentified as official will no longer be.”
