Page design is not a direct ranking factor for SEO success, but it can have an indirect impact on SEO.
A well-designed page with a good user experience can help increase the time users spend on the page, which can signal to search engines that the page is high-quality and relevant.
Additionally, good page design can help make it easier for search engines to understand the structure and content of the page, which can improve the chances of the page being correctly indexed and appearing in search results.
However, other factors such as technical SEO, content relevance, and backlinks are considered to be more important for SEO success.
