The search algorithm of Google is updated countless times a year, and this is perhaps surprising to hear. You may have noticed that core updates are happening after an announcement, but that is certainly not the case for minor changes. They occur without notice, and these upgrades are significantly minor. You would love to prepare and perhaps even benefit from Google algorithm update, and for that, one must review Google’s documentation on search engine optimization. Let me discuss with you the fine print.
What is Google Algorithm?
Google Algorithm is undoubtedly a complex system, and it is a process to answer search queries in the best possible manner. There are rules and data from the index, which helps to calculate or identify the web page best suited to answer the query. After this, the programmed ranking of search engines sends a signal to its hierarchy to organize the pages accordingly. They are arranged according to the relevance of search results.
How frequent are the Google Algorithm updates?
At the start, the frequency of updates for the Google Algorithm was significantly lowers than today. The frequency of updates has grown along with time, and we have already mentioned that countless minor updates take place today without notice. The micro-updates are constantly happening, and in most instances, the end-user is not impacted. However, Google occasionally announces significant algorithm changes, and for that SEO professional, web admins need to prepare a bit. Google spells out the significant change as core updates, and after the update, the core part of the algorithm will change. It could lead to a substantial shift in SEO or even user experience.
An insight into some significant Google Algorithm updates
There have been some core updates for the Google Algorithm undertaken in the past decade. Here are the details for readers.
- The first is the Caffeine index update in June 2010. It was a new indexing system, where the focus was to boost up search results for the user and publisher. Google was undoubtedly able to crawl and store data more efficiently. This update offered 50% fresher results for web searchers.
- The Panda update in 2011 was also significant, and via this update, Google levied a penalty on content farms, keyword stuffing. This update helped to identify spammy, low-quality content and removed them from high search engine rankings. It caused a tactical shift in SEO and black hat techniques; keyword stuffing was a thing of the past.
- The next year, Google introduced the Penguin update, which was intended to target websites, which had webspam and even manipulated link building.
Google has constantly been making core updates to algorithms, and that is to boost up user experience. Lately, there has been the Bert update, a natural language processing machine learning system. They are constantly at work looking to boost up user experience.
