Common Mistakes

• Treating it as one-and-done. Most signals drift over time as themes update, plugins change, and content moves. Audit at least monthly.
• Fixing symptoms instead of templates. If 100 pages have the same issue, the template is the problem. Fix once at the source.
• Skipping verification after fixes. Cache layers, CDNs, and stale indexes mean "fixed" rarely means "done" until you re-crawl.
