Frequently asked questions

Is SEO still worth doing in 2026?

Yes, but the bar is higher. Thin AI content gets ignored. Deep, original, well-structured content still wins — and gets cited inside AI Overviews.

Ahrefs or Semrush — which should I pick?

Ahrefs is stronger for backlinks and keyword research; Semrush is broader (PPC, social, content). Pick Ahrefs for SEO depth, Semrush if you want one tool for everything.
