Frequently Asked Questions (FAQ)
What is a good keyword density for SEO in 2025?
There is no single magic number, but a healthy keyword density for a primary keyword is generally between 0.5% and 2%.

Does keyword density still matter for SEO?
Yes, but in a more nuanced way than in the past. While Google is much smarter now, keyword density is still a fundamental signal of a page's topic and relevance. It's no longer about hitting an exact percentage, but about ensuring your primary and secondary keywords appear a reasonable number of times to establish topical authority without engaging in keyword stuffing.
Can I get penalized for high keyword density (keyword stuffing)?
Yes. 'Keyword stuffing' is the practice of unnaturally loading a webpage with keywords to manipulate search rankings. This leads to a poor user experience and can result in a manual penalty from Google or be devalued by its algorithms, causing your rankings to drop significantly.
