Our Verdict

If your SEO strategy hasn't changed since 2020, you're playing a different game. New SEO requires schema markup, llms.txt, AI crawler access, and structured FAQ content — none of which mattered in 2020.

Frequently Asked Questions

Are backlinks still important?

Yes, but quality over quantity. One link from a medical journal beats 100 directory links. And backlinks now also signal authority to AI systems, not just Google.

What's the biggest change?

The biggest change is that ranking #1 on Google is no longer enough. You now need to also be recommended by ChatGPT, Perplexity, and Google AI Overviews. That requires schema, structured data, and AI-specific optimization.
