Algorithm Updates
Panda updates
Google's Panda Update is a search filter introduced in February 2011 meant to stop sites with poor quality content from working their way into Google's top search results. Panda is updated from time-to-time. When this happens, sites previously hit may escape, if they've made the right changes. (Formed against Content spamming )
Content spinning
It is all about using a robot (software) to rewrite your article enough that another robot (Google) will think it’s a different article. It does this hundreds of times within minutes. The “new” content can be submitted to hundreds of blogs, usually with an SEO benefit in mind.
Penguin Updates (formed against Link spamming)
In 2012, Google officially launched the web spam algorithm update, which specifically targeted link spam and manipulative link building practices.
The webspam algorithm later became known (officially) as the Penguin algorithm update via a tweet from Matt Cutts, who was then head of the Google webspam team. While Google officially named the algorithm Penguin, there is no official word on where this name came from.
Link Exchange
It occurs when an agreement is made between two brands to trade links to boost SEO and site authority by essentially saying, “you link to me, and I'll link to you.” In essence, a reciprocal link is a quid pro quo, or a “you scratch my back, I'll scratch yours” situation.
Comment Spamming
It is a fundamental problem which has to be dealt by all the websites which allow commenting on their articles and blog posts. People try to post a comment on an article to win a free back link to their sites, thinking that the free back link will improve their search engine ranking and their website will start to rank higher in search results
Pigeon updates
Google Pigeon is the code name given to one of Google's local search algorithm updates. This update was released on July 24, 2014. The update is aimed to increase the ranking of local listing in a search. The changes will also affect the search results shown in Google Maps along with the regular Google search results.
Hummingbird updates
It is the code name given to a significant algorithm change in google search in 2013. Its name was derived from the speed and accuracy of the Hummingbird Algorithm. The change was announced on September 26, 2013, having already been in use for a month. "Hummingbird" places greater emphasis on natural language queries, considering context and meaning over individual keywords. It also looks deeper at content on individual pages of a website, with improved ability to lead users directly to the most appropriate page rather than just a website's homepage.
Semantic search results
It refers to the ability of search engines to consider the intent and contextual meaning of search phrases when serving content to users on the web. At one time, Search engines could only analyze the exact phrasing of a search term when matching results with a search query.
Ranked brain(using Artificial Intelligence)
It is a machine learning-based search engine algorithm, the use of which was confirmed by Google on 26 October 2015. It helps Google to process search results and provide more relevant search results for users.
Parked domain updates
A parked domain is a registered domain name that’s not linked to a website or email hosting service. Essentially, the domain isn’t actively being used. Instead, it’s parked for later use.

Pirate Update
There’s only one trigger for the Pirate update, and that’s being a website that publishes pirated content. More specifically, you’ll feel the effects of the update if your site has been reported for copyright infringement that violates the Digital Millennium Copyright Act .
In short, the DMCA issued that’s it’s a criminal offense to provide stolen or pirated media of any kind. Because pirating is such a widespread issue, Google decided to step up their monitoring of pirate sites with an algorithm update. If you’ve got pirated content on your site, and you’ve had multiple copyright infringement reports filed against you—including a report filed by the owner of the material—you’re not only going to be down ranked, but you’ll be removed from the SERPs altogether.
Mobilegiddon Update
“Mobilegeddon”, as panicking website developers have named it, is Google's new algorithm that takes mobile-friendliness into account when ranking search results. From 21st April, if your website isn’t friendly to mobile devices then it will fall in mobile search rankings.
Only time will tell how much of an effect the change will have, but Google is predicting it will have “a significant impact.” Around 50% of all searches are now done from tablets or smartphones, meaning that if your website ranks much lower for these users, you will see your traffic go down.
