Does Google need Analytics installed to create metrics?
-
Hi Mozers,
Does Google know time on site, number of page visits, bounce rate, etc. even if Google Analytics is NOT installed? Does it measure all that stuff anyway, and if you install the GA code on your site, that is so that YOU can see those metrics?
OR can Google only see those metrics if you install GA on your site?
Thanks! Jane

Answering your question about if can Google Analytics track your data even when is not installed? the answer is NO, it can't
Let me explain my point
Understanding Google Analytics reports and capabilities requires an understanding of the basic principles. Knowing what data Google Analytics can capture and how it interprets it is key to making sense of the software.
At its most basic level, Google Analytics consists of
- JavaScript code on each page of a website,
- A data collection service on Google's servers
- A processing engine that creates report data
1. Google Analytics JavaScript Code
When a visitor arrives at a page with tracking code, the code is executed by his browser. It collects information about the visitor's browser and computer settings, like screen resolution, operating system, etc. The script's visibility is pretty limited. It can typically only see what it's told.
The script then sets a few cookies containing some basic visit information. These cookies determine whether it is a new or returning visitor, among other things.
2. Google Analytics Data Collection Service
Next, all of this information must be sent to the Google Analytics servers so it can be processed. The GA tracking code sends the information by requesting a very small file, named __utm.gif. It appends all the cookie data and information it just collected to the query string for __utm.gif. This way, Google's servers have a record of when a file was requested and all of the visitor information about that pageview.
Many organizations store a copy of every tracking request sent to the data collection service - this is accomplished with the setLocalRemoteServerMode(); function in ga.js. Once you have a local copy of Google Analytics tracking requests, you can process them with Angelfish Software and turn them into interactive reports.
3. Processing Visit Information
In the last step, Google Analytics processes all of the __utm.gif requests, applies filters and config settings, and makes the data available to your account.
Visit data is typically processed every few hours, although this frequency has been increasing over time. Google rolled out a set of Real Time data reports in 2011 although the data available in these reports is not comprehensive.
IN SUMMARY
If you don't have the script installed on your site, Google Analytics cannot track your website data. OF Course Im talking just about Google Analytics, because I'm sure that if we talk about Google (Search Engine) is another history

Save a Google Analytics account
We recently started with a client who has Google Analytics already installed on their current site, but they have no idea the account login for it? Is there anyway to transfer ownership of this just based on the code?

Question re Google Analytics and its more accurate alternatives
Hi guys There are two main issues we have with Google Analytics, and I'd really appreciate if anyone has the time to give an answer to that. We completely miss organic traffic data before 7/22/2013 although our account is active since 2005. Any thoughts on that? Is it the not provided move that swiped out all data or something else? Even for the data we do have there is lots of inaccuracies, and we are thinking on switching or at least adding a new analytics software, any recommendations? (FYI, it turns out we do not keep access logs on the server for more than 2 months, and we might fix that for future references, but now we are looking for external solution). Any help will be much appreciated Thanks Lily

Does Installing Google Tag Manager Compromise Server Security?
Greetings MOZ community!!! Both my hosting company and developer have told me that in order to install Google Tag Manager it is necessary to disable the rule securing against malicious i-frame attacks in Mod Security and that this would leave the site (we operate on a virtual private server and out hosting company is InMotion Hosting) extremely vulnerable to attack. I can't believe that Google would write code that could allow potential security issues? Is this true? Does anyone know of a way to install GTM while maintaining site security? What functionality will we lose if we choose to stick with the old version of Google Analytics rather than upgrade? Thanks everyone!!!

How to filter many cities from Google analytics
I need to filter hundreds of cities from my traffic reports. I've been told that adding them all in this format: |Knutsford|Ripon|Cheadle Hulme|Congleton| and using the 'matching reg/exp from the drop down should do it... Unfortunately that doesn't seem to be working as I can still see cities like London in the results.... Any ideas?

What's the final word on Image Search tracking in Google Analytics?
Sorry if this has been answered but I can't seem to get a straight answer to my questions by searching around. How is traffic referred by Google Images counted in Google Analytics? I know it used to be referral traffic from google.com/imgres. A lot of things I have read say that it should all be under google/organic now, but my site still gets referral traffic from google.com/imgres, so that can't be. However I also get traffic as google/organic that I am pretty sure is from image search, because we don't rank for the keyword normally, but we do for image search. What's the deal? How is traffic from an embedded image in a regular result page counted? How can I segment my image search traffic better? It would be great to see image search traffic as it's own medium. I found a script here -- http://jrom.net/google-images-in-google-analytics -- that looks promising, has anyone used it or can recommend another way? I haven't used the GA API very much so I want to make sure the script is kosher and won't screw up my numbers.
