The main focuses of the Google algorithm updates from October 2023 and March 2024 are addressing low-quality or spam content. These updates target three categories of spam: scaled content abuse, expired domain abuse, and site reputation abuse. They aim to penalize mass-produced AI-generated content, misuse of expired domain authority, and 'parasite SEO' tactics.

To adapt SEO strategies in response to Google's core algorithm updates, businesses should:

• Evaluate and remove content that falls under the new spam categories.
• Ensure content is high-quality, human-written, and infused with E-E-A-T (experience, expertise, authority, trust) factors.
• Optimize website user experience (UX) and navigation.
• Create question-based content that aligns with how users structure search queries.
• Perform regular SEO audits to monitor performance and make necessary adjustments.

The Google core algorithm updates have had a significant impact on AI-generated content, penalizing it for lacking uniqueness and a human touch. AI-generated content that is generic, low-quality, or too similar to existing web content is being targeted by these updates. The updates aim to maintain efficient search results while ensuring content retains the 'human touch'.

Focusing on E-E-A-T is important for future Google core algorithm updates because these four themes—experience, expertise, authority, and trust—are foundational to a strong SEO strategy. High-quality content that demonstrates E-E-A-T helps build long-term resilience and ensures that businesses are less likely to be negatively impacted by algorithm changes.
