Welcome to the Q&A Forum

Just reviewed a WordPress blog that was launched in 2009 but somehow the privacy setting was to not index it, so all this time there's been a noindex, nofollow meta tag in the header. The client couldn't figure out why masses of content wasn't showing up in search results. I've fixed the setting and assume Google will spider in short order; the blog is a subdirectory of their main site. My question is whether there is anything else I can or should do. Can Google recognize the age of the content, or that it once had a noindex meta tag? Will it "date" the blog as of today? Has the client lost out on untold benefits from the long history of content creation? I imagine that link juice from any backlinks to the blog will now flow back to the main site; think that's true? Just curious what others might think of this scenario and whether any other action is warranted.
