Core update (algorithm core update)

What is known as a core update?

A core update is a broad update to Google’s algorithm that occurs several times yearly. These updates are non-specific, meaning they don’t have a specific purpose or goal behind them like others. They can, however, have a major impact on websites and their rankings in search engine results pages (SERPs).

Core updates are important for SEO professionals because they can help improve any website’s ranking, visibility, and overall performance in search engine rankings. It’s important to stay current with core updates to ensure your website is optimized for the latest algorithm changes. Additionally, monitoring any changes that could affect your website’s performance in SERPs is wise.

What is the difference between core and broad core updates?

The main difference between a Core Update and a Broad Core Update is that a Core Update focuses on improving the algorithm for all websites, while a Broad Core Update focuses on changes to more specific areas of the algorithm.

A Core Update will often include updates that improve website rankings overall and address issues with spam and duplicate content. With a Broad Core Update, Google can focus enhancements on particular aspects of its algorithms, such as Mobile First Indexing or Enhanced Structured Data, which can greatly impact SEO performance when properly implemented. Additionally, both types of updates are important for SEO professionals since they provide opportunities to ensure their websites remain up-to-date with the latest algorithm changes from Google and optimize their sites accordingly.
