Google Search’s Core Algorithm Updates
Coming in the top Google search results is the dream of every brand. And for all the good reasons: it surely does attract sizable organic traffic besides cementing your place in your domain. Google keeps rolling out patches and core updates from time to time to deliver users the most relevant results. But have you ever wondered how these core updates affect websites and their search visibility?
Google Core Algorithm Updates refer to the broad changes introduced to Google’s search algorithms and systems each year to enhance the overall quality of the search results. These updates influence how Google evaluates and ranks your website and interprets your content. This article discusses major Google core updates issued from 2021 till date.
What Should You Do With a Google Core Update?
Generally, when a new update is released, it takes a few days to weeks to roll out. So, your first task is to have patience till the entire update is rolled out. Once completed, Google recommends waiting another full week before you compare your website performance for a comparable period before and after the rollout.
The next step is to identify the pages and queries affected by the update and whether or not the content and changes on those pages offer real value to your website. Ensure your website offers a good user experience and the content aligns with search intent while providing helpful and reliable information.
Impact of Google Core Updates on SEO
The results may vary from one website or query to another. Individual websites or web pages can experience fluctuations in visibility, rankings, clicks and impressions.
If any of the pages show drastic changes after an update, then your SEO company must address the situation by studying Search Console data along with other key metrics to identify the root cause instead of blaming it all on the update. Apart from this, brands must also analyze the affected content and make necessary changes to align it with user search intent.
