The Content Avalanche
Everyone is using ChatGPT to pump out 50 articles a day. The internet is flooded with mediocre, perfectly-spelled, soulless content. 'Content is King' is dead when content costs $0 to produce.
The Return to Authority (E-E-A-T)
Google's algorithm now heavily favors E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness). If you write a medical article, Google doesn't care how good the content is; it cares if the author is a verified doctor.
Technical SEO and UX
Because content quality is harder to judge automatically, Google relies on user signals. Does the page load in under 1 second? Does the user click 'Back' immediately after landing (Pogo-sticking)? Exceptional UX and blazingly fast Next.js sites are your biggest SEO advantages now.
