- 01
WordPress Site Accidentally Noindexed: Find the Setting, Plugin, Theme, or Header
Check Settings → Reading first, then inspect the final robots meta tag and X-Robots-Tag header. Trace the directive through WordPress’s blog_public setting, SEO plugins, page-level controls, theme or child-theme filters, maintenance and staging tools, server headers, and cached edge responses.
- 02
Shopify Canonical URLs: Products, Collections, Variants, and Duplicate Paths
Shopify supplies canonical URL support automatically, but themes, apps, collection-context links, variant parameters, filters, markets, and custom code can still produce conflicting signals. Inspect the rendered canonical, identify the intended product or collection URL, and make internal links, sitemaps, redirects, and theme metadata agree.
- 03
Next.js Page Visible in the Browser but Missing From Google
Inspect the initial HTTP response and Google-rendered HTML, then verify route status, Server and Client Component boundaries, metadata generation, canonical URLs, robots directives, dynamic-route data, error handling, sitemap and robots files, and the deployed cache. A page that hydrates in a familiar browser can still send an empty, stale, redirected, or noindexed response to a fresh crawler.
- 04
Cloudflare Pages and Workers SEO: Redirects, Headers, Preview URLs, and Caching
Inspect the final Cloudflare edge response rather than only repository or origin files. Determine whether Pages, a Pages Function, or a Worker owns the route; then verify redirects, header precedence, preview-domain noindex, custom-domain normalization, cache state, status codes, and canonical URLs on the exact public deployment.
