Google Penguin Update
April 2012 marked the release of the Penguin update. Web spam is the sole focus of this update. It made adjustments to keywords stuffing, links coming from spam pages, anchor texts and links relevant to spam. Penguin detects over-optimization of tags and internal links, poor neighborhoods, and bad ownerships. Latest version of Penguin (3.0) released October 2014.

What was the purpose of the Penguin update?
Penguin is mainly designed to combat web spam and optimize search results for users. In order to achieve such improvements, the content quality and technical performance of websites is improved.

When was the Penguin update implemented?
Google Penguin rolled out its first update on April 24, 2012. We also known this version as Penguin 1.0. Late that year, two data refreshes took place. Only the database needed for the algorithm was updated here, not the algorithm itself.
The Penguin update 2.0 was released on May 22, 2013. Google then updated its data again almost four months later.
Google began rolling out Penguin 3.0 on October 17, 2014. Prior to that, manual updates were applied.
Penguin 4.0 became a core part of the search engine’s algorithm thanks to their experience in the Fall of 2016. The updates to the Panda update have been continuously taking place since then, as with the Penguin updates.
Algorithm updates and their consequences for webmasters
If you purchase backlinks or manipulate links in some other way, the Penguin update may affect your website (for example, not adhering to the Google webmaster guidelines). Google Penguin used to devalue whole domains if web spam was detected. The penalty may eventually lead to an exclusion from Google’s index. The Penguin filter now works on a URL basis; if the filter detects web spam, individual sub-pages may suffer a ranking drop.

With implementing the continual updates, there is always the possibility that the sanctions imposed on affected websites will be withdrawn more rapidly. It was much more difficult to get liberated from the penalty when the updates were still done manually, and it sometimes took until the next Penguin update to do so.

For the SEO world, the Penguin upgrade had far-reaching repercussions. If link building and receiving backlinks via guest submissions or link exchange were still a big part of SEOs’ activity before then, link building has fallen out of favour.
Link building has been more difficult since then. More efforts are now being made to enhance voluntary linking to your own website using high-quality content. Simultaneously, additional marketing channels such as social media are being leveraged to expand the website’s reach and, as a result, receive backlinks and traffic.

What types of webspam is the Penguin update designed to combat?
Webspam comes in a variety of forms, according to Google’s “quality rules.” Webspam, according to it, includes the following strategies or features:

Unnatural links: purchasing or renting links from link farms can get these connections.
Artificial linking: When a website is mostly composed of keyword links, it is almost often an instance of webspam.
Rapid link growth: If a website gains many incoming links in a short period, Google may consider it spam.
What can webmasters and SEOs do if the Penguin upgrade affects their site?
Penguin has harmed those who discover should begin studying the link structure right once. Links from online catalogues or incoming links from link farms, as well as a lousy neighbourhood, can cause devaluation. A warning of “unnatural links” that Google sends to webmasters via the Google Search Console is a good clue that it has enabled the Penguin filter.

Prior link-building efforts should be evaluated and analysed in this scenario, so that it minimised the effects of Google Penguin on the afflicted websites.

One solution is for webmasters to contact the connected websites and request that the hyperlinks be removed. In addition, Google has provided an alternative as the Disavow Tool. Backlinks can be deemed invalid immediately using the programme.

Penguin’s Triggers
Penguin addressed two practises in particular:

Link schemes – Creating a fake picture of popularity and importance by developing, acquiring, or purchasing backlinks from low-quality or unrelated websites in order to influence Google into granting high rankings. An insurance firm in Tampa, for example, may spam Internet forums with spam remarks promoting itself as the “best insurance company in Tampa.” falsely inflating its appearance of relevance with these unnatural links. Or, an equivalent company might pay to possess links reading “best insurance firm in Tampa” appear on an unrelated third-party article about dog grooming; content that has no relationship to the subject .

Keyword stuffing – Populating a webpage with large numbers of keywords or repetitions of keywords to control rank via the looks of relevance to specific search phrases. For instance, an unnatural repetition of keywords on a page might look like:

How am I able to discover if I’ve been hit by a Penguin?
There is a difference between a Penguin penalty and a manual penalty for unnatural linking. In brief, Penguin may be a Google index filter applicable to all or any websites, whereas a manual penalty is restricted to one website that Google has determined to be spamming. These manual penalties could also result from a website being reported by Google users for spam, and it’s also speculated that Google may manually monitor some industries (like payday loan companies) quite others (like cupcake bakeries).

If your website’s analytics show a drop in rankings or traffic on a date related to a Penguin update, then you’ll suffer from this filter. Make certain you’ve ruled out expected traffic fluctuations from phenomena like seasonality (for instance, a Christmas forest in April), and punctiliously evaluate whether your keyword optimization or linking practices would be deemed spammy by Google, making your site susceptible to an update like Penguin.

How to get over Penguin
Unlike a manual link penalty, in which you want to file a reconsideration request with Google once you’ve cleaned the house, you do not file such an invitation to possess a Penguin penalty lifted. Rather, taking action to remedy problems will often earn ‘forgiveness’ subsequent time Googlebot involves crawling your site. These recovery steps include:

The removal of any unnatural links over which you’ve control, including links you’ve built yourself or have caused to be placed on third-party websites.
The disavowal of spammy links that you simply can’t control
The revision of your website’s content to remedy over-optimization, ensuring that keywords are implemented naturally rather than robotically, repetitively or nonsensically on pages where this is often no relationship between the subject and therefore the keywords getting used
In sum, Penguin remedied a severe weakness in Google’s system that enabled their algorithm to be ‘tricked’ by large numbers of inferiority links and, therefore, the keyword over-optimization of pages. To avoid having your website devaluated by Google for spam practices, all content you publish should reflect language, and your link-earning-and- structure practices must be supposed “ safe.”

Other facts about the Penguin update
Penguin was initially a separate “filter” through which search results were passed, but in September 2016, Google announced Penguin had become a part of the core program ranking algorithm.
Google staffer John Mueller called Penguin a site-wide algorithm, meaning that an outsized number of low-quality links pointing to at least one page of your website could end in a discount of Google’s trust on your entire website. However, some SEOs have asserted that, by the iteration of Penguin 4.0, the filter may have softened a touch in order that it’s not penalizing entire domains.

Key differences between Google’s Panda and Penguin updates
Google rolls out many updates during a year. With just one aim to supply quality content to its audience. Any program, whether Google or Bing or the other program, the prime aim is to satisfy the searchers Google’s Penguin and Panda, also specialise in that:

Google Panda – Google Panda was introduced in February 2011 and therefore the basic purpose of this is often to stop from showing any content within the SERPs which uses spamming to rank itself. To be more specific, it checks contents that have tons of backlinks but very thin content.

To protect your website from getting any penalty by Panda update is that you simply remove all the toxic backlinks for your websites.

Google Penguin – the newest update of Google Penguin unrolled in October 2014 with the target to stay the utilization of keywords under check. Keyword stuffing may be a major issue which provides irrelevant content to people. Webmasters want to insert irrelevant keywords or use keywords more frequently within the content in places where it has been unnecessary. Google considers such activities to be inorganic.

Summary, Thus Penguin updates is:

Penalizing for Getting Unnatural Links for Keywords
Getting Paid Links
Getting links for suspicious sites
Getting links from Unrelated and shallow sites
Getting links with exact anchor Texts
