A category page is either your most valuable SEO landing page or a thin duplicate that Google ignores. The difference is whether anyone wrote real content on it. Here is how to decide which of your category pages deserve to be indexed and how to fix the rest.
Background
Category pages exist to group related content. From Google’s point of view, they are either valuable hub pages (with unique intro copy, curated links, often ranking for broad keywords) or near-empty lists of titles that duplicate signals from the articles below. The default in most CMSes — auto-generated category pages with just a title and a list — falls in the second bucket and quietly hurts your site’s overall quality score.
How to tell
- Your category pages have only an
<h1>and a list of post titles. - Pages report shows category URLs as “Crawled — currently not indexed”.
- Your category pages rank for nothing —
site:yourdomain.com/category/x/returns the page but it earns no impressions. - You have category pages with fewer than 5 articles.
Quick verdict
Index category pages that have unique intro copy (200+ words), at least 5 articles, and clear topical focus. Noindex (or delete) the rest. Empty or thin categories drag down your overall site quality signals — Google notices.
Step by step
- List every category page on your site. Visit each one as a logged-out user. Anything that is “title + auto list of posts” with no intro paragraph is a candidate for noindex.
- For each candidate, decide: kill it or write content for it. If the category has fewer than 5 articles, kill it (merge into a sibling category). If it has 5+ articles and represents real topic territory, write a 200-300 word intro that summarizes the topic.
- Add internal links from the intro to your 3-5 best articles in that category. This is what turns a category page from “duplicate list” into “valuable hub”.
- For categories you keep, make sure they have a self-referencing canonical, a meaningful
<title>(not “Posts in Category X”), and a meta description. - For categories you noindex, set
<meta name="robots" content="noindex, follow">—followmatters so Google still crawls the article links from that page. - After 30 days, recheck Pages report. Categories you wrote real content for should move from “Crawled — currently not indexed” to indexed. If they don’t, the content is still too thin or too duplicate of the articles below.
Common pitfalls
- Noindexing every category page as a default rule. If a category is well-developed, an indexed category page can rank for broad terms the individual articles cannot.
- Writing the same 100-word boilerplate intro for every category to “make them unique”. Google detects the near-duplicate pattern.
- Linking from category to category in a footer mega-menu without any unique anchor text. Internal links lose value when the anchor never varies.
- Killing a category that has external backlinks. Check Search Console -> Links report first. If a category page has inbound links, redirect it to the merged sibling, do not 404 it.
- Confusing category pages with tag pages. They serve different purposes — see the tag-pages article for tag handling. Category should be a hub; tag is a cross-cutting filter.
Who this is for
Content site owners with 5-50 category pages auditing their site’s overall quality. Anyone with categories that show up as “crawled — not indexed” and want to know whether to fix or kill.
When to skip this
Sites with no category structure (single chronological blog feed). Or sites just launched with no Search Console data yet — write content first, audit categories at month 3.
FAQ
- How much intro copy is “enough” for a category page?: 200-300 words of original copy that says what the category is, who it is for, and what the standout articles are. Less than that and Google treats it as thin; much more and you start writing an article instead of a hub page.
- Should I link from articles to their category page?: Yes — breadcrumbs and a “back to category” link both pass internal-linking signal and help users. Just do not stuff it 5 times in the article body.
- Can a category page rank for the same keyword as an article in that category?: They can compete (keyword cannibalization). Pick the intent: broad / browsing → category page; specific question → article. Make titles distinct, and link from one to the other.
- What about empty categories I might fill later?: Noindex now, write articles, remove noindex once you have 5+ articles and intro copy. An empty category indexed and ranking for nothing is a quality signal liability.
