0The Google Penguin Update launched on April 24. According to the Google blog, Penguin is an “important algorithm change targeted at web spam. The change will decrease rankings for sites that we believe are violating Google’s existing quality guidelines.” Google mentions that typical black hat SEO tactics like keyword stuffing (long considered web spam) would get a site in trouble, but less obvious tactics (link incorporating irrelevant outgoing links into a page of content) would also cause Penguin to flag your site. Says Google,
Sites affected by this change might not be easily recognizable as spamming without deep analysis or expertise, but the common thread is that these sites are doing much more than white hat SEO; we believe they are engaging in web spam tactics to manipulate search engine rankings.
Site owners should be sure to check their Google Webmaster accounts for any messages from Google warning about your past spam activity and a potential penalty. Google says that Penguin has impacted about 3.1% of queries (compared to Panda 1.0’s 12%). If you saw major traffic losses between April 24th and April 25th, chances are Penguin is the culprit, even though Panda 3.5 came out around the same time.
Unfortunately, Google has yet to outline exactly what signals Penguin is picking up on, so many site owners that were negatively impacted are in the dark as to where they want wrong with their onsite SEO. Many in the SEO community have speculated that some contributing factors to Penguin might be things like:
1. Aggressive exact-match anchor text
2. Overuse of exact-match domains
3. Low-quality article marketing & blog spam
4. Keyword stuffing in internal/outbound links
It’s important to remember that Panda is an algorithm update, not a manual penalty. A reconsideration request to Google won’t make much a difference–you’ll have to repair your site and wait for a refresh before your site will recover. As always do not panic if you are seeing a down turn in traffic, in the past when there is a major Google update like this thing often rebound. If you do think you have some sort of SEO penalty as a result of either the Google Panda or Google Penguin updates, please contact your SEO service provider to help or start trouble shooting.
