I read an interesting post on a Stanford students SEO Blog. It talks about future things that might be in the next "Zebra" algorithm update: http://www.seobiology.com/algorithm-update/ Summary of the Off Site Things Mentioned in the post: Class C to IP Ratio used to detect black hat TLD Composition to check for natural linking Ratio of Referring Domains to Number of Different Anchors Average number of links per ref domain Ratio of inbound Web 2.0 Links to ref domains Link Velocity / Link Acquisition Rate The post discussed a variety of different things that Google could use to detect spam tactics, and how to prevent them. Do you think the things he mentioned are legit? Summary of the On-Site Things Mentioned: Analyzing Social Reach vs Social Shares Better at Penalizing Spun Content (It talked about how they'll detect it) Number of Pages Getting Traffic will be used to effect rankings Number of Searches That your Branded Keyword / Website Name Gets User Metrics: Time on Site, Dwell Time, CTR will have more influence Number of Long Tail keywords ranking Its an interesting post... definitely worth a 5 minute read. http://www.seobiology.com/algorithm-update/ Seems like a fairly new blog. I'll keep you guys posted if I find anything else interesting. Is the stuff in the post true? Could everything in this post be true? If so, I need to start being a bit more social and watch some of my tactics, haha.
