Main website site.com's menu bar is having 50 links, the same menu section with 50 links we have placed in the footer. Which means 50 links in the header and 50 links in the footer.
The same header (50 links) & footer (50 links) we are using for blog.site.com
Below are my queries.
1. Keeping the header (50 links) and footer (50 links) the same on the website will hurt SEO?
2. Shall I need to add nofollow tag for footer links (50 links)?
3. Using main domain.com links in the header (50 links) and footer (50 links) of blog.domain.com is that spamming?
