Yes, having at least 600 words on a page is a common recommendation for SEO, as search engines tend to favor content-rich pages. However, for pages such as "Contact Us," which are typically straightforward and concise, it can be challenging to meet this requirement without adding irrelevant or unnecessary content.
One solution to this issue is to provide additional context or information related to the purpose of the page. For example, you could include a brief introduction or explanation of the purpose of the page, as well as any relevant details or instructions that users may need to know.
Another approach is to include a short form or survey on the page, which can help engage users and provide additional value beyond just the basic contact information. This can also help to capture important data or feedback from users that can be used to improve the website or business.
Finally, it's worth noting that while having a minimum word count on a page can be beneficial for SEO, it's not the only factor that search engines consider when ranking pages. Other factors such as page authority, relevance, and user engagement are also important, so focusing on these elements can also help to improve your SEO performance even if you can't meet the 600-word recommendation on certain pages.
