I have a side project site that is a new domain, as I was getting things ready I put robots.txt on the site and disallowed all. I built a few external links, a couple with the same anchor text.
I googled the site and noticed the standard "A description for this result is not available because of this site's robots.txt" notification but also noticed the title was exactly the same as the anchor text I had used on the external sites.
I just found this interesting that Google, not being able to read my site looked at external anchor text to give the page a title. That anchor text variation isn't used on the site anywhere.
Am I right with this observation or could it be something else?
