Google Algorithm Changes Explained by Augustine Fou

  1. 1. Major Google Algo Changes Explained Dr. Augustine Fou October 2013 -1- Augustine Fou
  2. 2. In Layman’s Terms “I’ve been asked by many clients about the Google algorithm changes that have happened over the last few years. This is a deliberately oversimplified explanation of what the major changes consisted of. For a more detailed and technical explanation, I will point you to my colleague, Glenn Gabe’s blog and articles (see links below).” -- Augustine Fou -2- Augustine Fou
  3. 3. Panda - 2011 “A major algorithm update hit sites hard, affecting up to 12% of search results (a number that came directly from Google). Panda seemed to crack down on thin content, content farms, sites with high ad-to-content ratios, and a number of other quality issues. Panda rolled out over at least a couple of months, hitting Europe in April 2011.” Source: -3- Augustine Fou
  4. 4. Penguin - 2012 “After weeks of speculation about an "Over-optimization penalty", Google finally rolled out the "Webspam Update", which was soon after dubbed "Penguin." Penguin adjusted a number of spam factors, including keyword stuffing, and impacted an estimated 3.1% of English queries.” Source: -4- Augustine Fou
  5. 5. Hummingbird - 2013 “Announced on September 26th, Google suggested that the "Hummingbird" update rolled out about a month earlier. Hummingbird has been compared to Caffeine, and seems to be a core algorithm update that may power changes to semantic search, [natural language queries], and the Knowledge Graph for months to come.” Source: -5- Augustine Fou

  7. 7. Dr. Augustine Fou – Digital Consigliere “I advise clients on optimizing advertising across all channels. One main area of focus is reducing ad waste due to fraud – fake impressions, clicks, leads, and sales. Another area is improving effectiveness. This is rooted in an understanding of how search works.” FORMER CHIEF DIGITAL OFFICER, HCG (OMNICOM) MCKINSEY CONSULTANT CLIENT SIDE / AGENCY SIDE EXPERIENCE PROFESSOR AND COLUMNIST ENTREPRENEUR / SMALL BUSINESS OWNER PHD MATERIALS SCIENCE (MIT '95) AT AGE 23 ClickZ Articles: Slideshares: LinkedIn: -7- @acfou Augustine Fou
