1seo: Should I add a robots follow meta tag to my pages?

Robots file is employed once you have duplicate content that you simply don’t wish to be indexed, otherwise you wish to make a no follow rule for specific areas of your Websites, you wish one in every of these files.If you still want to add robot meta tags, read this: meta-tag-definitive-guide

The default for all search engine spiders is to automatically follow the links that it finds on any given page, which makes any "robots follow" tag redundant. If you *don't* want the search engine spider to follow the links, you can try the "no follow" tag, but it may or may not be obeyed by all robots

The "revisit after" tag is not necessary, nor is it helpful. The search engine spiders work on their own timetable, and couldn't care less what your revisit tag says. I've heard that the tag was actually created for one specific search engine a long time ago, but I've never bothered to confirm it. At any rate, there's no need to clutter up your code with it as today's engines ignore it.
