When does PR update? When does the Alexa update? When are pages that are already index, update? If you can answer these questions that be really helpful. Thanks.
PR shows the backlinks, of your website. Nothing more. Alexa traffic rank is showing the traffic rank of your website (lower - better). Websites are indexed in google some time after they get first backlink. Google bots permanently within 1-2 days are passing through your website and craw pages again.
Guess no one could answer most of your questions, but here is my try: PR updates all the time and used to gets exported 3/4 times a year, but it's now getting exported quite fast. Alexa rank changes a lot and based on your website current ranking could updates on daily basis. Index update is a part of Data Refresh and Google gets faster and faster, so based on your website backlinks profile newly created pages could be indexed with no time: Hours or even Minutes. Hope i was clear and helpful
Both of them are update every second, just alexa show the update everyday, google not sure, sometime one month, sometime two months, sometime three months
Google used to update toolbar PR about once every 3 months but have been more frequent this year. Alexa updates every day. Pages that are indexed are updated when Google crawls the page after you make changes to it I think.
There's no definite time when google updates PR, while Alexa updates is not that important now. About indexing of google they frequently index your site when they see any updates from your sites.
Alright thanks for the help Seems a bit of different suggestions/time periods but i know the general ball park of when things will happen.
