When building META keywords tags for web pages, there isn't a strict 'best' number of keywords. In the past, SEO strategies often recommended including multiple keywords in META tags to improve web page search engine rankings. However, as search engine algorithms have evolved, particularly Google's, this practice has gradually become ineffective and may even be considered over-optimization, leading to decreased page rankings.
Modern SEO places greater emphasis on content quality and keyword relevance rather than quantity. Therefore, META keywords tags should include a few precise and highly relevant keywords. It is generally recommended to include no more than 10 keywords, ensuring each is closely related to the page content. Too many keywords may not only be unhelpful for SEO but also make the page appear unprofessional or be deemed keyword stuffing by search engines.
For example, consider a webpage about healthy eating; reasonable META keywords might include: - healthy diet - nutritious food - healthy recipes - natural ingredients - balanced nutrition. These keywords reflect the page's theme and are specific enough to help target users find the page via search engines.
In summary, the number of keywords in META keywords tags should be limited to a few precise and relevant terms, which can help search engines understand the page content while avoiding the negative effects of keyword stuffing.
