How Often Does Google Update Title, Description etc. on Search Engine? Also How Often are the Backlinks Updated?? Thanks!
It depends on how well-linked you are and how frequently you update your site. If you're cnn.com, for example (high link pop, frequent updates), you might see Google recache pages very frequently. If your site is brand new, you'll probably see sporadic updates. Backlinks are updated on a daily basis. You won't see either the link: command or webmaster tools reflect that activity, but its happening. Google just likes to play with a closed hand.
Backlinks like the other guy said is daily, however the title/description depends on how much you usually update your website, if you are updating your website daily already you will probably see the updates the day after. It is usually with in a week
Usually within a week for the title, description etc. but different data centres will update at different dates/ times so you may see old and new titles in searches at different times of the day until all data centres are up to date. I find Google's idea of backlinks goes up and down unpredictably.
