Key Takeaways
1. Fresh content is becoming crucial for SEO as large language models (LLMs) favor newer articles.
2. Changing publication dates may positively impact Google rankings, contrary to previous beliefs.
3. Content recency’s importance varies by topic; rapidly changing fields like finance prioritize the latest information.
4. Older, high-quality content can still be effective if regularly updated and maintained.
5. Trustworthiness and relevance are important factors considered by LLMs, alongside content freshness.
In the age of ChatGPT, Perplexity, and Google AI Overviews, a traditional SEO element is returning: the freshness of content. A fresh study from Seer Interactive indicates that large language models (LLMs) prefer newer content rather than older pieces. This trend of recentness has important consequences for those creating content strategies.
The Myth of Publication Dates
For many years, it was thought to be a myth in SEO that just changing the publication date could elevate a page’s ranking in Google. However, in the time of LLMs, there might be some validity to this idea. A recent analysis looked at over 5,000 URLs from log files of AI tools including ChatGPT, Perplexity, and Google AI Overviews, examining the relationship between publication dates and visibility. The findings are quite remarkable: 89% of the content identified by LLMs was released between 2023 and 2025, whereas only 6% of interactions with AI involved materials that were older than six years.
Topic Variability in Content Recency
The impact of recency differs depending on the subject matter. In rapidly changing areas like finance, there is a high demand for the latest information – content that was published before 2020 is seldom shown. The travel sector also has a tendency to highlight more current pieces. On the other hand, more stable fields, such as energy or DIY topics like building a patio, still allow for older, well-crafted articles to be featured by AI systems.
In fast-evolving industries like finance or technology, being visible means needing regular updates and a continuous flow of new content. This is where the recency of content becomes very important – new or recently updated pieces usually rank better in AI systems. However, in more stable areas, having lasting evergreen content can still work well, as long as it continues to be of high quality and relevant.
Enhancing Visibility of Older Content
Older, high-quality articles still have worth – well-thought-out updates can greatly improve their visibility. To keep a strong presence in AI overviews and chatbot results, it is crucial to continuously update content while maintaining its depth and detail. Although large language models generally prefer recent pieces, they also consider factors like trustworthiness and relevance.
