Yes, it is generally recommended to "noindex" pagination pages (pages 1, 2, etc.) in WordPress for better SEO. Pagination pages often contain duplicate or thin content that can dilute the overall SEO value of your site. By setting these pages to "noindex," you prevent them from appearing in search engine results, which helps to keep your site’s content focused on higher-quality, unique pages that are more valuable to users and search engines. This approach improves the overall crawl efficiency and ensures search engines prioritize your most important content.
