Let's see if I can explain this
Google's serp shows the date of Nov 19, 2012 before the description for my Index.html page...I'm not sure why. I cannot locate any date tag, "last-modified" date , or other date indicator, within the source code. I first noticed this date appearing a day ago.
I switched my static site to a Wordpress blog on Nov 19, 2012. I add a new post to my blog a few times a week. I know Google crawls my site daily. The cache date of my Index page is March 12, 2013.
I'm a bit concerned this may deter visitor interest if Nov 19, 2012 remains - several months from now (may give the sense the blog is outdated).
I'm curious why this is happening, so if anyone has any clue I would love to hear it.
