Spam Updates

Spam updates are designed to make Google better at identifying spammy content and practices. These can include, but are not limited to:

  • Cloaking: Presenting different content to Google and users
  • Keyword stuffing: Unnaturally forcing keywords into content
  • Scraping content: Plagiarizing content from other sites

Sites that violate Google’s spam policies may receive a Google penalty. This harms the site’s visibility in search results. Google released spam updates in June 2021, November 2021, and October 2022. 

Prior to this naming convention, Google also released the following web spam updates:

  • Florida (2003)
  • Jagger (2005)
  • Panda (2011)
  • Penguin (2012)

Tip: Review your content with Semrush’s On Page SEO Checker. It provides optimization ideas and flags any issues with keyword stuffing.

Reviews and Product Reviews Updates

In April 2023, Google released a reviews update that affected reviews about products, services, and things.

The goal was to reward original, well-researched product reviews that help people make decisions.

Best practices include evaluating from the user’s perspective, providing evidence of experience with the review subject, and explaining what sets something apart from its competitors.

Previously, reviews updates were product reviews updates. Released in April 2021, December 2021, March 2022, July 2022, September 2022, and February 2023.

Helpful Content Updates

Helpful content updates are “notable” refinements to Google’s helpful content system. This system aims to reward sites that deliver a great experience and leave users feeling satisfied.

Google recommends that sites create original, reliable content for people—not search engines. But confirms that SEO “can be a helpful activity.” 

Google released helpful content updates in December 2022 and August 2022.

Tip: Use Semrush’s Topic Research tool to develop content ideas that your audience will find helpful. You can find commonly searched questions, popular headlines, and more.

Page Experience Updates

Google released the page experience update for mobile in June 2021. And a page experience update for desktop in February 2022.

The Page Layout Algorithm Improvement Update (2012)Mobile-Friendly Update (2015), and Speed Update (2018) also related to page experience.

These kinds of Google updates aimed to reward pages that deliver a great user experience. For example, pages that are fast, secure, and mobile-friendly.

In April 2023, Google confirmed that page experience was part of the helpful content system. And updated its page experience recommendations.

Tip: Semrush’s Site Audit tool helps you identify, prioritize, and fix technical issues on your site. Many of which relate to page experience.
