- An HTML sitemap provides a basic navigational structure for a website in page form, usually placed on the 404 page or footer. It creates more internal links to improve SEO and domain authority.
- An XML sitemap helps search engines better understand a website structure when crawling. It is generated automatically for WordPress sites or using a sitemap generator. The sitemap URL must be submitted to search engines through their webmaster tools.
- The nofollow attribute tells search engines not to consider links as votes for the linked pages. It is commonly used for comment links and ads to avoid passing link juice to unrelated sites. Site owners can check if a link is nofollow by inspecting its HTML code.
