If you run a WordPress website with Yoast SEO, you have likely wondered how many tags you should add to each post. Some site owners add dozens of tags hoping to capture more search traffic, while others ignore tags entirely. Tags can be useful for organizing content and improving navigation, but overusing them can create SEO problems. Understanding how tags work in WordPress and how Yoast handles them will help you use them strategically rather than randomly.

What Are Tags in WordPress?
WordPress offers two main ways to organize posts: categories and tags. Categories are broad groupings that represent the main sections of your site, such as "SEO," "Web Design," or "Social Media." Tags are more specific descriptors that highlight particular topics within a post, such as "local SEO," "Core Web Vitals," or "link building." Each tag automatically creates an archive page that lists all posts using that tag.
How Yoast Treats Tags
Yoast SEO does not decide how many tags you should use, but it does control how tag archive pages appear in search results. In Yoast settings, you can choose whether tag archives should be shown in search results, customize their SEO titles and meta descriptions, and include or exclude them from the XML sitemap. Yoast also focuses on the focus keyphrase for posts, which is separate from WordPress tags. Adding tags does not improve your Yoast readability or SEO score.
So, How Many Tags Should You Use?
For most websites, a good rule is to use between three and ten tags per post, and only when those tags are genuinely useful. More important than the number per post is the total number of tags across your site. Each tag should ideally be applied to multiple posts. A tag used on only one article creates a thin archive page with little value for users or search engines.
- Use tags consistently: Reuse existing tags instead of creating new variations.
- Avoid near-duplicates: Do not create "SEO tips," "SEO tip," and "tips for SEO" as separate tags.
- Do not repeat categories: Tags should not duplicate category names.
- Think about users: Tags should help readers find related content.
The SEO Risks of Too Many Tags
Excessive tagging can create hundreds of low-quality archive pages that contain the same posts in slightly different combinations. This leads to thin content, duplicate content, and wasted crawl budget. Search engines may spend time crawling unimportant archive pages instead of your valuable posts. In some cases, tag archives compete with your main articles for the same keywords, causing keyword cannibalization.
Should Tag Archives Be Indexed?
For many sites, setting tag archives to noindex in Yoast is a sensible choice, especially if tags are numerous or lightly used. However, if your tag archives are curated, contain several posts, and include unique introductory content, they can serve as useful landing pages worth indexing. Evaluate your tag pages in analytics and Search Console to see whether they attract traffic or simply add clutter.
How to Clean Up Existing Tags
If your site already has too many tags, start by exporting a list and reviewing how many posts use each one. Merge duplicates, delete tags used only once, and redirect removed tag URLs to relevant categories or posts where appropriate. Create a tagging guideline document so writers apply tags consistently in the future. This cleanup often improves crawl efficiency and site clarity, which supports broader digital marketing goals such as engagement and conversions.
Better Ways to Improve Post SEO
Tags are a minor organizational feature, not a ranking tactic. To improve post rankings, focus on high-quality content that satisfies search intent, a well-chosen focus keyphrase, strong headings, internal links to related articles, optimized images, and fast page performance. Yoast's content analysis can guide these improvements, but its suggestions should support, not replace, writing for real readers.
Categories vs. Tags in Practice
Think of categories as the table of contents for your blog and tags as the index. Most posts should belong to one primary category, while tags describe specific details. Keeping this distinction clear makes navigation intuitive and prevents overlapping archive pages.
Conclusion
With Yoast SEO, there is no single perfect number of tags, but three to ten relevant, reusable tags per post is a practical guideline. Keep your overall tag list lean, avoid duplicates and one-off tags, and decide deliberately whether tag archives should be indexed. Used thoughtfully, tags improve navigation and content discovery. Used carelessly, they create clutter that can weaken your SEO. Focus on organization for users, and your site structure will support search performance.
