Meta keywords were once a cornerstone of on-page SEO. Website owners would list dozens of keywords in a hidden HTML tag, hoping search engines would use them to rank pages. Today, the landscape is very different. If you are asking how many meta key words for SEO you should use, the short answer may surprise you. In this article, we explain the history of the meta keywords tag, how major search engines treat it today, whether you should still use it, and where your keyword optimization efforts should focus instead.

What Is the Meta Keywords Tag?
The meta keywords tag is an HTML element placed in the head section of a web page. It lists keywords that describe the page's content, separated by commas. Visitors never see it, but search engines could read it. In the early days of the web, search engines relied on this tag because their algorithms were less capable of understanding content on their own.
Why Search Engines Stopped Using Meta Keywords
The meta keywords tag was easy to abuse. Website owners stuffed it with irrelevant or excessive keywords, including popular terms unrelated to their content, to attract traffic. Because the tag was invisible to users, there was no accountability. As a result, search engines began to ignore it. Google officially stated in 2009 that it does not use the meta keywords tag in web search ranking. Bing has indicated that it may treat heavy keyword stuffing in the tag as a spam signal rather than a ranking boost.
So, How Many Meta Keywords Should You Use?
For Google rankings, the number of meta keywords does not matter because the tag is ignored. Many SEO professionals recommend leaving the tag out entirely. If you choose to use it for internal reasons, such as site search or content organization, keep it minimal, typically three to five highly relevant keywords. Never stuff it with dozens of terms, as this offers no benefit and may look spammy to some search engines.
Risks of Using Meta Keywords
Although the tag does not help rankings, it can introduce minor risks:
- Revealing your strategy: Competitors can view your source code and see your target keywords.
- Spam signals: Excessive or irrelevant keywords may be viewed negatively by some search engines.
- Wasted effort: Time spent maintaining meta keywords could be better used on meaningful optimization.
When Meta Keywords Might Still Be Used
There are a few niche cases where keyword tags still have some purpose. Some internal site search tools and content management systems use them to categorize content. Certain smaller or regional search engines have historically considered them, though their influence is minimal. Some news platforms use a separate news keywords tag for specific publishing systems. For most websites, however, these use cases are not relevant to search rankings.
Where to Focus Keyword Optimization Instead
Instead of the meta keywords tag, concentrate on the elements that truly influence rankings and click-through rates:
- Title tags: Include your primary keyword naturally near the beginning.
- Meta descriptions: While not a direct ranking factor, compelling descriptions improve clicks.
- Headings: Use H1 and H2 tags to structure content around relevant topics.
- Body content: Cover the topic thoroughly, using related terms and natural language.
- URL slugs: Keep URLs short, descriptive, and keyword-relevant.
- Image alt text: Describe images accurately, including keywords when appropriate.
- Internal links: Use descriptive anchor text to connect related pages.
- Structured data: Help search engines understand your content with schema markup.
Modern Keyword Research Best Practices
Effective keyword strategy today begins with understanding search intent. Identify what users want when they search a term, whether information, comparison, or purchase. Group related keywords into topic clusters and create comprehensive content that addresses the full range of questions. Use tools like Google Search Console, Ahrefs, or Semrush to find opportunities and track performance. Focus on topical authority rather than repeating a single keyword many times.
Should You Remove Existing Meta Keywords?
If your site already has meta keywords, removing them is optional. They are unlikely to harm Google rankings if they are relevant and limited. However, if they are stuffed or outdated, cleaning them up is a good housekeeping step. Many SEO plugins no longer include a meta keywords field by default, reflecting the industry consensus that the tag is obsolete.
Conclusion
How many meta keywords should you use for SEO? For Google, the answer is effectively zero, because the tag is not used for ranking. If you include them for other purposes, keep them to a handful of relevant terms and avoid stuffing. Your keyword optimization efforts are far better spent on title tags, headings, content quality, internal linking, and search intent. Modern SEO rewards relevance and value, not hidden lists of keywords.
