Google Algorithm :

Google Algorithm is way different when compared to standard algorithm. The standard definition of an algorithm is: a set of rules for solving a problem in a finite number of steps. But coming to SEO the meaning of an algorithm will be like this : It sets some set of rules which the websites have to follow in order to rank their websites in the Google search. But how did it decide which results to show you, and in what order?

Google has a very complex algorithm for serving search results, and it changes relatively frequently. There will be updates every year and sometimes this will be a minor update and sometimes it will be a major update. Reports suggest that Google algorithm will have 500 to 1000 updates every year.

As the Google algorithm “reads” a webpage, it prescribes a pre-ordained numerical value to each trait it’s seeking on the page. That numerical value is then added to the end result. Thus, the web page that has the most desirable traits will rise to the top of the page rankings because the algorithm assigns it more importance.

These calculations by the Google platform are conducted incredibly quickly, and the rankings may fluctuate as web developers manipulate the attributes that contribute to page rankings across a website, or on a single page.

Therefore, rankings as assigned by the Google algorithms are fluid. A page that ranks third for a keyword may rise to first or fall to tenth as the content on both it and the other pages in the results change. Usually, the top spots are held by businesses that do search engine optimization, or SEO, on their sites.

How the algorithm for google search will work :

For instance, an individual who inputs “buy running shoes”, The algorithm is adjusted for each search, and can be altered by even the slightest changes to spelling and word order. The results are then given to the user, who can decide which site to visit.

How the Google algorithm works for SEO :

Google algorithm partially uses keywords to determine page rankings. Here the keywords refers to “What the users will type in the search bar. For instance, the user types “buy movie tickets” then the entire phrase will be a Keyword for Google and it shows the results for this query from the Google server that contains websites which are related to the “Buying the movie tickets”. The best way to rank for specific keywords is by doing SEO. SEO essentially is a way to tell Google that a website or web page is about a particular topic.

Years ago, it was common practice for many sites to “keyword stuff” their content. In essence, they assumed that the Google algorithm would think that the more keywords that were written, the more important the page should be.

Once Google realized this, they altered their algorithm to penalize sites that stuff their pages with keywords, as well as many other “black hat” SEO practices. Because of this, you should avoid any tactic that is done with the aim of outsmarting search engines. Although they may not notice right away, Google will eventually pick up on what you are trying to do, and your rankings will suffer.

When The Google Algorithm Are Introduced:

google algorithm update

In September 2002, Google makes the first publicly announced update to its search algorithm.A number of Internet commentators view this as the death of PageRank (the name for Google’s system for ranking pages) and a significant decline in the quality of Google’s search results.

In February 2003, Google announced the Boston update at SES Boston. Also from April to November Google released algorithms namely “Cassandra“, “Dominic“, “Esmeralda“, “Fritz“, ” Florida” updates to tackle link spam, including mutual links between co-owned websites, as well as hidden text and hidden links.

In January 2004, Google announces the “Austin update“, to continue with the work of combating SEO tactics that Florida had made good progress on. In the same year on February, Google announces the Brandy update, a massive index expansion, Latent Semantic Indexing (LSI), increased attention to anchor text relevance, and the concept of link “neighborhoods.”

In January 2005 To combat link spam, Google, Yahoo! and Microsoft collectively introduce the ” nofollow attribute “. In the same year Google announces the “Allegra” and “Bourbon” updates for which the effects on the sites are unclear.

In December 2005, Google begins rolling out the “Big Daddy update“, continuing for the next few months until March 2006. The update changes URL canonization, site redirects, and related items. The updates are continued every year for tackling small issues without effecting the rankings.

In August 2009, Google announced an algorithm named “Caffeine“, this update is announced on August 10, 2009. It promises faster crawling, expansion of the index, and a near-real-time integration of indexing and ranking.But the rollout is made live on June 8, 2010.

In February 2011, Google launches “Google Panda“, a major update affecting 12% of search queries. The update continues with the earlier work of cracking down on spam, content farms, scrapers, and websites with a high ad-to-content ratio.The rollout is gradual over several months, and Panda will see many further updates.

Google launches its “Webspam update” which would soon become known as Google Penguin on April 2012 and it was updated every year.

In August 2013, Google releases “Google Hummingbird“; a core algorithm update that may enable more semantic search and more effective use of the Knowledge Graph in the future.

In July 2014, Google announces the rollout of “Google Pigeon“; a major update to its search algorithm for “local” searches such as searches related to events or businesses near one. The Pigeon update gives more weight to various search signals to deliver more relevant local results.

In May 2015, Google says it has made a core algorithm change impacting “quality signals“. Before the official announcement, commentators had dubbed the changes as “Phantom 2“.

In October 2015,Google announces that “RankBrain“; a machine learning-based engine (using neural networks), has been the third most influential factor in its search rankings for the last few months. The actual rollout date is not confirmed, but commentators pin the launch time to Spring 2015. It is most useful for new search queries, that account for about 15% of search queries.

In the last update Google rolls out a ranking signal boost to benefit mobile-friendly websites on mobile devices. This is the second update of this sort, with the previous update in April 2015.

From then Google doesn’t have announced any new updates till now but SEO’s and webmasters should be very careful because if at all the updates are released further it will effects the rankings of the sites. So we should be careful with the backlinks, on-page points to see that traffic will not decrease to the sites.

Effects and remedies for Google Algorithm changes:

First ask which (if any) algorithms might be affecting your site.

  • Internal algorithms (on-page, technical, etc.)
    Panda, Phantom, Penguin
  • External algorithms (links, citations, etc.)
  • Third-party influence algorithms (ads, etc.)
    Panda, Phantom

These algorithms will affects the sites and we loose the traffic and the rankings there are some points that will solve the problem.

For Panda update :

  • Frowns on “thin” content. Length of content can matter (as a signal of time, effort and completeness), but there are exceptions.
  • Duplicate content: NOT a penalty, but it does confuse Google as to which page you want to have ranking. Make sure all your titles and descriptions are unique.
  • Content clarity: make sure all your content is well-written and focused on its topic.
  • Content specificity: make sure content is relevant to your key topics.
  • Content length (these are all rough suggestions, not hard and fast rules!)

Blog posts should be about 35–550 words.

In-depth articles 750 words+.

  • Content technical issues: grammar, spelling, readability

 For Penguin Update :

google penguin update

Real-time Penguin is good news, since adjustments occur as soon as the page is crawled; however, Penguin is now harder to detect, since now only individual pages or sections of a site will drop in ranking, not the whole site.

Your pages can also be hit by an indirect Penguin effect, if some of the pages that link to them are hit by Penguin. The links from those pages to your pages will no longer pass along the ranking power they once did.

The only way to really recover now if Penguin impacts pages on your site is to get quality links to those pages to replace the ones that Penguin devalued. Google says you should still disavow any bad links to your site that you find.

 Mobile-friendly Update :


google mobile friendly update

Since it’s inception the mobile friendly update has an major effect on the sites which are not accessible on mobile. A “mobile-friendly” label used to appear next to sites that met this threshold in the search results, but no longer does. Google has announced two “mobile-friendly” algorithm updates so far, which allegedly devalue the ranking of non-mobile-friendly sites in mobile search results.

Intrusive ads Update :

In August 2016, Google announced that it would begin to devalue the mobile rankings of sites that had certain kinds of interstitials that prevented users from being able to immediately see the actual content upon page load. In January 2017, they confirmed that the update had rolled out. This has effected a lot with the sites who has more pop-up’s that cover the main content, either immediately after a page opens from a search result or while scrolling down that first page. Also the standalone interstitials that must be dismissed before the user watch the content.
