This question came from our site for professional and enthusiast programmers.

Google Analytics only works for visitors running javascript, that also wait for your javascript to load and communicate with Google.

This would exclude most bots and people who did not want to wait for your page to load.

Webmaster tools on the other hand also shows information about how a site performs in the search result pages.

I personally think the analytics data is more useful.

how about semrush? do you know about it. are their data relevant? – danniel Apr 5 '11 at 16:42
semrush seems to be about getting guesses about the traffic of your competitors, probably similar to alexa. If you want information about your own sites, go with the google tools – dontomaso Apr 5 '11 at 17:11
I think with google analytics you can now use images for tracking thereby removing the need for javascript? – Codek Apr 7 '11 at 7:21

This is a bit like wondering why your Gmail, Google Voice and Google Wave inboxes all contain somewhat different messages.

Google Analytics and Webmaster Tools aren't directly comparable. They do different things. At any rate, both use approximate data and this can be dicey when the overall volume is low and estimations are difficult.

Google analytic tool is better which gives in-depth information about your visitors.

It provides in depth details about users behavior in your website, You can use this data to analyze and improve your website's sales or objective.

In Goolge web master, you get SEO related data such as Keywords' Impression & position & Clicks details.

Google web master tool is mainly useful to get bird view of your organic traffic from Google. But, Analytic provides much more information about visitors.
