SEO deployment guide: zero-ops edge publishing with Cloudflare Pages
Git-driven SEO deployment in practice: commit to build, atomic publish to every edge node.
Quick answer
How do I fix mass-generated long-tail pages being flagged as duplicates?
Every page needs a unique canonical, an independent title, and differentiated body content. Pages that only swap keywords with identical structure need real differences added or search engines will fold them.

In-depth analysis
SEO is fundamentally about making canonical signals (canonical link, sitemap, structured data) clear and traceable so search engines never classify your pages as duplicates. At deploy time hand the built artifact to the edge platform and lean on static fallback plus security headers to hold the line on stability.

FAQ & pitfalls
How often does search engine cache refresh?
Bump lastmod to trigger a sitemap re-crawl, paired with an independent canonical. Do not rely on forcing a CDN purge — after the static output updates, crawlers return naturally.

What readers are asking
Questions that keep coming back in reader feedback, already answered.
- 01
How do the canonical and sitemap domains stay in sync?
Both must read site.origin (the Astro site setting). A hardcoded domain breaks everywhere the moment you change domains or use a Preview URL, and the pages get treated as duplicates.

How do I stop generated pages being flagged as duplicate content?
Every page needs a unique canonical, its own title, and genuinely differentiated body copy. Pages that only swap a keyword while keeping an identical structure must gain real differences, or search engines fold them together.

Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.
