when i open my robots.txt file it says: User-agent: * Disallow: / . what does this mean? does it block all robots? if so, my site might not be showing up on google!
what's the correct way to write robots.txt? which files should i 'disallow' and which ones should i leave open?
if i write robots.txt incorrectly will it show an error in Search Console, or will it just silently hide the site?
