There are a lot of free counters that also collect traffic stats like google analytics, sitemeter etc. There are a whole bunch of sites that offer free visitor tracking for website and they offer these services for free. I have a bit of experience on Google analytics. They offer a lot of options for webmasters to track visitors and optimize and promote their site likewise but the data is not up to date, it takes a day or two for google analytics to update stats.

The matter is about counters for websites. But I wonder if these can be used for blog analytics. Any information on this will be appreciated.
