Quick summary
Standardize URL variants
Pick one canonical version (https, www/non‑www, trailing slash) and enforce it consistently.
Fix canonical and duplicate signals
Use canonicals, redirects, and clean internal links so duplicates consolidate properly.
What to fix first (and why)
Start with issues that block crawling or indexing—because content can’t rank if it can’t be discovered. Run a quick scan with the Website Analyzer to catch obvious structure signals, then verify metadata with the Meta Tag Analyzer and crawl rules with the Robots.txt Tester. If duplicates are involved, follow How to Fix Duplicate Content and the canonical basics in What Is a Canonical Tag?.For a baseline definition, see What Is Technical SEO?, and for execution playbooks use Website SEO Audit Checklist and How to Analyze a Website.

Frequently Asked Questions
Which technical SEO issues are most urgent?
Crawl blocks, accidental noindex, incorrect canonicals, and major duplicate URL variants are typically the most urgent.
Should I use redirects or canonicals for duplicates?
Use redirects when a page should not exist; use canonicals when multiple versions must exist but should consolidate signals.
How do I confirm a fix worked?
Re-scan the page, check that internal links point to canonical URLs, and verify robots/canonical meta signals on the live HTML.
