- [Consolidate thin and duplicate pages](https://seo-mcp.io/t/consolidate-thin-and-duplicate-pages) — Thin pages targeting the same topic compete with each other. Group URLs by shared queries and near-duplicate titles, choose the strongest by impressions and links, merge unique material, and 301 the losers. Keep pages that serve genuinely different intent.
- [Implement hreflang for every locale](https://seo-mcp.io/t/implement-hreflang-for-every-locale) — hreflang tells Google which language and region variant to serve. Every variant must list all variants plus itself, using valid language or language-region codes and absolute URLs. Choose one delivery method, keep each variant self-canonical, and validate reciprocity after every locale change.
- [Canonicalize duplicate URLs](https://seo-mcp.io/t/canonicalize-duplicate-urls) — Duplicate URLs split signals across protocol, host, slash and parameter variants. Pick one canonical form, emit one absolute self-referencing canonical per page, and align internal links, sitemap entries, hreflang and og:url with it. Use redirects when the duplicate should not exist at all.
- [Add canonical URLs with the Next.js Metadata API](https://seo-mcp.io/t/add-canonical-urls-with-the-next-js-metadata-api) — Next.js App Router resolves metadata per route, so each page can declare its own canonical URL instead of inheriting one global value. Set alternates.canonical in the page metadata export or generateMetadata, keep it absolute and self-referencing, and make sure template redirects and trailing-slash handling agree with the URL you declare.
- [Handle faceted navigation with canonicals](https://seo-mcp.io/t/handle-faceted-navigation-with-canonicals) — Facets multiply URLs into thousands of near-duplicates. Decide which combinations deserve indexing, give those unique titles and copy with self-canonicals, and canonicalize the remainder to the closest indexable parent. Block infinite parameter spaces and monitor crawl stats for facet-heavy URLs.
- [Fix redirect chains and loops](https://seo-mcp.io/t/fix-redirect-chains-and-loops) — A redirect chain adds latency and leaks crawl signals. Point each legacy URL directly at the final destination, use 301 or 308 for permanent moves, and keep the map in source control. Audit with curl -IL and update internal links so chains stop growing.
- [Set canonicals and sitemap with Astro integrations](https://seo-mcp.io/t/set-canonicals-and-sitemap-with-astro-integrations) — Astro needs a production site value before canonicals and sitemaps can be correct. Set site in astro.config.mjs, install the @astrojs/sitemap integration, and let it emit sitemap-index.xml with child files. Then render an absolute canonical in the layout from Astro.url and Astro.site so every page references itself.
- [Monitor index coverage in Search Console](https://seo-mcp.io/t/monitor-index-coverage-in-search-console) — The Page indexing report groups URLs by status and reason. Review it weekly, sample each reason, and separate intentional exclusions from regressions. Track counts over time instead of reacting to a single spike, and use URL Inspection to confirm individual cases before changing code.
- [Canonicalize filtered category URLs](https://seo-mcp.io/t/canonicalize-filtered-category-urls) — Filtered category URLs usually should not compete with the clean category page. Keep the base URL canonical and self-referencing, and canonicalize filter combinations to it unless a combination has its own demand and unique inventory. Never canonicalize to a blocked or missing URL.
- [Set meta and canonicals with useSeoMeta](https://seo-mcp.io/t/set-meta-and-canonicals-with-useseometa) — Nuxt 3 resolves head tags per route through useSeoMeta and useHead. Set title, description, og and canonical in the page that owns the route, using an absolute URL built from runtimeConfig.public.siteUrl. Set the same origin in nuxt.config.ts so the sitemap module and prerender steps agree with it.
- [Add an x-default hreflang entry](https://seo-mcp.io/t/add-an-x-default-hreflang-entry) — x-default marks the page served when no language or region matches, usually a selector or the global version. Add it to the hreflang set, ensure it returns 200 and is indexable, and never point it at a geolocation redirect. Validate reciprocity with the rest of the set.
- [Fix collection canonicals and product schema offers](https://seo-mcp.io/t/fix-collection-canonicals-and-product-schema-offers) — Shopify renders collection pages at multiple filter and pagination URLs. Keep one canonical per collection, canonicalize filtered views to the base when they are not meant to rank, and emit Product markup whose offers match the real price, currency and availability shown in the buy box.
- [Verify indexing with URL Inspection](https://seo-mcp.io/t/verify-indexing-with-url-inspection) — URL Inspection shows the indexed version Google holds for one URL: crawl time, selected canonical, status code and blocked resources. Run it before rewriting content or changing redirects. It separates indexing failures from ranking problems and confirms whether Google sees the same page your browser renders.
