Google search engine is used as an index to search results on the internet based on the algorithms set by Google. Its primary purpose is to find and sort the material in billions of web pages and provide users with the results they need for the entered query. This information is crucial for businesses, SEO practitioners and content developers who wish to keep their content relevant and indexed in the search engines. The major areas that we will discuss include how often Google changes its search algorithm, the various categories of updates and the effects that these changes have on SEO.
The Nature of Google Algorithm Updates
Google’s algorithm updates can be categorized into two main types:
i. Core Updates: These are general modifications that impact the general search engine mechanism. These types of updates are usually launched several times per annum and can substantially shift the search rankings of many sites.
ii. Minor Updates: Google alters the algorithm every single day even though it is not entirely significant; it is usually a slight modification. The alterations mentioned above may not be immediately visible to the majority of users but work towards improving the accuracy and relevance of the search results.
But as most of the changes go unnoticed by the general public, every change may bring significant shifts even if they are not very dramatic to particular industries.
How Often Does Google Change Its Algorithm?
i. Daily Changes: As per the information revealed by Google the search engine undergoes various alterations in the form of algorithm update daily.

These actions are not made publicly and formally, and they result to small fluctuations to the ratings.
ii. Core Updates: Unlike minor broad core updates that occur daily, Google core updates happen multiple times in a year. These updates are bigger changes made with the aim of enhancing the quality of the algorithm and regarding some important issues, such as the ranking of pages or the definition of intentions of the users in the search process. For example, there were confirmed core updates in 2022 and 2023, and each of them affected hundreds of thousands of websites.
iii. Spam and Security Updates: Google also regularly releases updates that are targeted specifically towards combating Spam as well as enhancing the security of the platform. These are not as frequent as daily changes, however, they play a vital role in Search Engine optimisation to ensure that the results are not rigged by webmasters who use SEO techniques that are against Google rules on SEO.
