Magento seo question. Nofollow on top links like cart/login?
While reading up on seo I thought to add no follows to default links that exist on every page. Cart. Login. Checkout. TC. Faq.
When looking up my site on Google using site:domain I realized that the top pages were the ones that have links in headers and footers.
By adding rel=nofollow to functional links like cart/login/etc all the seo juice is given only to relevant category and content pages (that dofollow).
Question: Is this smart to do seo wise? And how can this be done via xml or Phtml using no follow? Or can it be tackled via robots?
Many thanks ......
