It’s important to remember that a Google algorithm change may have been responsible for large changes in SEO visibility. We track every update carefully and below you’ll find the list of all known official and unofficial updates since the first in 2002
Lily Ray talks about Google algorithm updates and core updates.
What is a Google Algorithm Update?
The Google search algorithm is responsible for taking web pages, found by its crawlers and added to its index, and sorting them into results for queries. Over the years it has developed from something simple – easily tricked by carefully crafted URLs and content – to an algorithm that includes machine learning and AI.
Are Google Algorithm updates important for SEO?
The goal of every Google algorithm change, also called a Google Update, is to (further) increase the quality of the search results for the user. Google uses more than 200 ranking factors to determine the quality and relevancy of every URL. Google’s ranking algorithms help get the most relevant information from the Google-Index.
Algorithm updates may affect your rankings and visibility but if you are following the Quality Rater Guidelines and writing the content that your users want to see, a Google Algorithm update may never affect your rankings, at least directly. Other sites can gain and lose visibility and this will indirectly affect your own SEO rankings.
