If you don’t know nothing about robots.txt and controlling robots through Meta tags -and don’t want to take the pain of editing the txt file in your root folder and disallowing each search engine crawler manually - worry not! There is an easy way to get this done in Wordpress.

Goto Dashboard> Options> Privacy settings.

You will find two options here.

1 - I would like my blog to be visible to everyone, including search engines
2 - I would like to block search engines, but allow normal visitors

Now, it’s obvious that the first option is what you need.Ensure that the second option is not selected.

What happens when you select the first(Correction - Second) option?
It causes the - meta name=’robots’ content=’noindex,nofollow’ to appear automatically into the page head section of every page. Thus it will not allow Google or any other search engine to crawl the site at all.

It also creates a robots.txt file in the root folder(Only if the WP installation is in the root folder, and there is no existing robots.txt file), in which the command for disallowing all crawlers into the entire directory.

Ensure that you select the first(I would like my blog to be visible to everyone, including search engines) radio button. Be a smart SEO.
