The world of SEO (Search Engine Optimization) is constantly changing, and it’s not uncommon for past common sense to no longer apply. As of fall 2026, Google’s search algorithm continues to evolve to become smarter and more focused on “user experience.” In this article, we will explain the latest algorithm trends and countermeasures that site operators should take immediately.
Three important trends in SEO algorithms for fall 2026
1. Rigorous evaluation of AI-generated content (full-scale operation of SGE)
Google is standardizing an AI-powered search experience called “Search Generative Experience (SGE).” As a result, zero-click searches are increasing because AI answers simple information (weather, calculations, word meanings, etc.) on the search results screen. In addition, “commonplace articles (mass-produced, low-quality content)” that are simply automatically generated by AI are now strictly excluded through spam updates.
2. Super emphasis on “Experience” in “E-E-A-T”
Among Google’s quality evaluation guidelines, E-E-A-T (Experience, Expertise, Authority, and Trustworthiness), Experience is being emphasized more than ever before.
Articles that simply summarize information written on other sites'' will be ranked lower, and there is a growing tendency for content that includes original experiences and images such as actually buying and using a product’’ or ``covering the product with one’s own feet’’ to dominate the top rankings.
3. Core Web Vitals (CWV) and UX Evolution
Core Web Vitals, which measure page loading speed and visual stability, have become the baseline ranking factor. Nowadays, it is assumed that the algorithm goes one step further and incorporates the essential UX (user experience) of whether the user was able to achieve the goal without getting lost within the site (low bounce rate, length of stay, and flow of actions).
SEO measures to survive in the future
In order to win with SEO in the future, you need to focus on the following points, rather than making minor keyword adjustments.
- Thorough primary information: Incorporate unique data, interviews, case studies, and failure stories that only you (your company) can write into your content.
- Transparency of author information: Clarify who wrote the book and prove that they are experts in the field through their profile, SNS links, etc.
- Utilize videos and rich content: In addition to text, place explanatory videos and illustrations (infographics) as needed to help users understand.
Summary
The key to SEO in the fall of 2026 will be how well you can provide “fresh information unique to humans that cannot be written by AI.” Google’s algorithm is constantly learning what content truly satisfies users. Instead of just looking at what search engines think, create content that answers 120% of the concerns of the users in front of you.
