How many times does Google release the algorithms and updates visible to users?

Google release their algorithm update through their blogs.

Checking and reading the Google Webmaster Blog is a great place to start. Read over any information they have posted, and look at what the update was meant to target. If your site was hit, it’s likely these are the things you need to work on. If you still need more, Search Engine Land has a number of great staff writers and columnists who cover all the algorithm updates very well.
