How We Set Tag Archives to Noindex on BlitzMetrics Using Rank Math

Tag archive pages on blitzmetrics.com were crawlable by Google but had no indexing directive — meaning Google was free to index them, diluting the site’s content authority with hundreds of thin archive pages. Setting them to noindex in Rank Math SEO took less than five minutes and is the correct long-term configuration for most WordPress sites.

This same configuration is part of the standard Rank Math setup BlitzMetrics applies on client sites. When we set up RankMath Pro for a local service business on WP Engine, tag archive noindex was one of the first settings we configured — because thin auto-generated pages consistently drag down content quality signals across any WordPress site.

💡 Key Takeaway
There is an important distinction between a page being crawlable and a page being indexed. Crawlable means Google can visit and follow links. Indexed means Google stores it in search results. Tag archives should be crawlable but not indexed — they pass link signals through to posts without polluting the index with thin pages.

Crawlable vs. Indexed: Why the Difference Matters

Tag archives should be crawlable — Google needs to follow the links from tag pages to the individual posts they reference. But tag archives should not be indexed, because they are thin, auto-generated pages with no unique content. Indexing them wastes crawl budget and adds low-quality pages to the index that can drag down the site’s overall content signals.

The correct setup: crawlable (no robots.txt disallow) + noindex meta tag. This is exactly what we configured.

Why This Fix Was Needed After the robots.txt Change

Before this session, BlitzMetrics had a Disallow: */tag/ rule in its robots.txt that blocked Google from crawling tag pages at all. We removed that disallow rule because blocking crawling is a heavier-handed approach that prevents Google from following links through tag pages to actual content.

Once we removed the disallow, tag pages became crawlable again. But we needed to make sure they would not get indexed. That is where the Rank Math noindex setting comes in. Full details on the robots.txt fix are in our article on how we fixed the robots.txt blocking BlitzMetrics from Google.

How We Configured It in Rank Math

In the WordPress admin, we navigated to Rank Math SEO → Titles & Meta → Tags. The setting panel shows two radio-style options: Index and No Index. The Index option was selected by default.

We clicked No Index and saved changes. Rank Math then adds a <meta name="robots" content="noindex"> tag to every tag archive page automatically. No custom code required.

We reloaded the settings page after saving to confirm the No Index option remained checked. It did.

✅ Pro Tip
Always reload the Rank Math settings page after saving to confirm the change registered. Rank Math’s interface uses React components that can sometimes show stale state. The page reload forces a fresh read from the database, confirming the save actually took effect.

Critical Decisions Made

Noindex, not disallow: The previous robots.txt approach blocked crawling entirely. The noindex approach allows crawling (so Google follows links through tag pages to posts) while preventing the tag pages themselves from appearing in search results. This is the SEO-correct configuration.

Verified the save: Rank Math’s settings panel uses a React-based interface where form inputs do not always register correctly with standard click actions. We confirmed the save by reloading the page and checking that the No Index option was still selected.

Left other archive types alone: We only changed the Tag archive setting. Category archives, author archives, and date archives were left at their existing settings and would need a separate review before changing.

⚠️ Watch Out
Only change tag archive settings — not category archives — without a separate audit. Category archives often have unique editorial content or are the main navigation structure for a site. Setting them to noindex without reviewing could suppress pages that are driving real organic traffic.

For any WordPress site generating significant tag archive pages, this is a quick configuration that prevents thin auto-generated pages from diluting your site’s content signals in Google. It pairs directly with the robots.txt fix that re-opened tag pages for crawling. Both changes together create the correct setup: crawlable, not indexed.
