Canonical URLs: how to consolidate duplicate content correctly
A canonical tag is a suggestion, not an instruction. Getting it consistently right across a site is what makes the suggestion credible.
Technical SEO ensures search engines can crawl, render, understand and index your pages. The developer-owned essentials are: a correct robots.txt, an accurate XML sitemap, self-referencing canonicals, clean status codes and redirects, server-rendered content, semantic headings, structured data, and Core Web Vitals within thresholds.
Verify with the URL Inspection tool in Search Console. It shows the rendered HTML Google actually sees, which is the only version that matters.
Crawling and indexing changes can appear within days; ranking effects typically take weeks to months. Core Web Vitals field data uses a 28-day window, so allow a month before judging.

A sitemap is a list of the URLs you are confident about. Padding it with redirects and noindex pages teaches Google to ignore it.
Google renders JavaScript. It renders it late, inconsistently, and other crawlers often do not render it at all.
