I can help you out as this issue DROVE ME NUTS.
1. I didnt have a Robots.txt (yet)
2. I had Yoast installed
3. Im pretty sure it created a Robots.txt even though it doesnt exist in my root (.com/here)
4. My Google webmaster tools shows this
User-agent: Disallow: /wp-admin/ Disallow: /wp-includes/ Disallow: /cgi-bin Disallow: /wp-admin Disallow: /wp-includes Disallow: /wp-content/plugins Disallow: /plugins Disallow: /wp-content/cache Disallow: /wp-content/themes Disallow: /trackback Disallow: /feed Disallow: /comments Disallow: /category//* Disallow: /trackback Disallow: /feed Disallow: /comments Disallow: /? Disallow: /?Allow: /wp-content/uploadsAllow: /assets Create a Robots.txt
1. login to wordpress 2. Click SEO in your side toolbar (Yoast WordPress Plugin settings) 3. Go to edit files under SEO (in the side toolbar)
And now you have the option to edit your Robots.txt file.
