Ignoring technical SEO is still a big one. I have audited sites with good content trapped behind bad internal linking, duplicate tags, slow pages, broken schema, or no clear canonical setup. People blame Google when the site is sending mixed signals.
What is the biggest SEO mistake people still make in 2026?

People share common SEO mistakes, including chasing keywords blindly, publishing thin AI content, ignoring technical issues and failing to build trust.
Answers & Discussion
Publishing too much weak AI content is the mistake I see constantly. The articles look clean, but they say nothing new. Google may index them, but users do not trust them and other sites do not reference them. Scale without quality is dangerous.
The biggest mistake is treating SEO as a checklist instead of a strategy. People install a plugin, add keywords, publish articles, and expect traffic. They never ask who the page is for, why it deserves to rank, or how it supports the business. Tactics without strategy create noise.
