Understanding the algorithms used by search engines, like Google, can be confusing. Let's start at the beginning:
What is the search engine algorithm?
An algorithm is a mathematical process that a computer uses to solve a problem or to answer a question. Google, launched in 1998, is the leading search engine. The search engine algorithm is designed to find files on the Internet.
Google uses many algorithms, but the first one ever used is called PageRank, which measures the importance of all webpages (PageRank is named Larry Page, developer and co-founder of Google). PageRank works by calculating the quantity and quality of links to some webpages to determine an estimate of the website’s importance, and hence its ranking, compared to other websites in the same domain or category.
Google used the assumption that more important sites are more likely to have more links than other websites and thus ranks the website with the highest ranking on the search engine results page (SERP). Page rank is Google's most popular algorithm. An entire industry of business services to utilize PageRank is now called Search Engine Optimization (SEO).
Google's algorithms change about 500-600 times in a calendar year – more than once every day. Changes are implemented to make the search experience more relevant to the user. Most of the changes are simple, and the site rating does not usually change to any noticeable degree.
Almost two decades ago, Google has been improving its search engine service and becoming more sophisticated, with huge algorithms affecting the way websites are ranked.
What is the update algorithm?
Major updates are posted regularly, whether it is named or not. The companies that provide SEO services are dedicated to finding out how each change will affect the websites that it runs. The stakes are very high, especially for e-commerce websites. If a website is built and maintained using best practices, with an emphasis on unique content and an easy-to-navigate user experience, the website will be fine. Powerful PageRank turns into a Super PageRank that provides more website traffic.
Some of the named updates over the years are: Panda, Penguin, Hummingbird, Pigeon, Possum, RankBrain, Mobilegeddon and Pirate. Each update relates to a specific aspect of the website, such as website quality linking, search for semantic content, and mobile (or responsive) websites for mobile.
How are algorithm updates detected?
This is cool: some updates are announced. Others are secretly released and fully achieved by viewing pageviews. Google sometimes confirms updates after the update starts. Google recently committed to emphasizing algorithm updates. The SEO industry carefully monitors metrics to determine which aspect of the page rank is affected. When they notice significant changes in the search results, they conclude that an update of the algorithm has taken place.
What is uniquely updated?
On Wednesday, March 8, 2017, industry experts noticed major changes while using Google Tracking Tools. This algorithm has been changed Unique update.
Until experts fully understand the meaning of page rankings, the nature of the update is speculative. Fred Update shows early signs of its association with link quality – not content. Gary Illyes, a Google Webmaster Trends analyst, tweeted a picture of Fred the fish's colorful squad on March 7: "DYK For every search result, there may be multiple candidates for the title and the candidate who thinks it works best to inquire users appears."
Since there is an evaluation to determine the best result for your query, searching on pages that rank better than your website may reveal opportunities to improve your content without duplicating it. Unique content and link quality to and from your site will improve your PageRank. The last massive log update to date is Google Penguin 4.0 (Phase 1 and Phase 2). This update largely eliminates the penalty for bad links on sites, and in turn reduces bad links, which still negatively affect ratings, but not to the point that sites are penalized.
Penguin was important because it targeted low-quality websites with 'spam' content. Their main concern was to report websites that would harm user devices or mobile phones.

The Google Penguin Update was under development, under review, for two years before its release. The update actually started on September 27, 2016. This update was unusual because it was multi-stage, it took too long to release from most other algorithm updates.
The second stage was launched on October 6, 2016. After the launch of this second stage, the "temperature" algorithm decreased and returned to relatively normal. Moz reports the weather daily that shows temperature or turbulence in Google's algorithm. When Google makes a change, there is often a change in page rankings. The temperature of this week is 94 ° C. This indicates the potential impact of a unique update.
Knowing the complex nature of assessing a website's suitability, understanding these updates, and knowing how algorithms affect and rank the website is the work of the companies that provide SEO services. You can choose to do this work within the company, but hiring an outside company to handle your SEO is often money well spent.
