How long does it usually take for published articles to show up on Google Scholar? The title pretty much says it all - what's the typical delay with which Google Scholar indexes newly published articles? (Note I'm not talking about citations, but about the article showing up at all.)

Edit: the article in question went for over six months after being published (in a well-regarded Springer journal with its own Wikipedia page) without appearing on Google Scholar, until it received a citation, at which point it was added to Google Scholar almost immediately. One more motivation to write papers that get cited. :)

Edit 2: Another article in an even more mainstream journal took a little over seven weeks.
My article showed up in a few days. Since google is crawling, I believe (although I am not certain), that updating other sources such as policy, government, medical repositories and other resource hubs that allow you to update fields, add links etc, without needing to upload the article, increases the external links with the article page. This might not be necessary to expedite the process, but if the article is not showing up within the normal period of time (which could be a week), I believe this would be a good step to take. This advice also applies for anything else such as websites and blogs. Actually my repository link showed up in google before the actual journal page did!
