Analytics bounce rate change
-
Hi mozzers,
I have a little riddle. A few weeks ago the bounce rate on one of our website dropped 90% - from 45 % average to 5 % average. We haven't changed much in the code of the site, layout or anything else. The traffic is pretty stable too.
Anyone can guess why? Or have experienced something similar?
-
Thank you Keri. Such a speedy response!
And NOW it makes sense. So happy to have that resolved.

Having it there twice can cause issues. I myself have an old post with this exact issue. What happens is that the tracking code fires twice.
My simplistic understanding, which may be good enough here:
Firing only once in a session: visitor didn't go to any other page, they're a bounce.
Firing more than once in a session: visitor did something else! they didn't bounce!
IIRC, my pageviews and pages per visit were also higher. Get the duplicate GA code off, and make an annotation in Google Analytics itself of what happened, so six months or two years down the road someone can look and understand why the metrics are wonky for that time span.

I know this is an old thread, but it might be exactly what I need.
A client site has seen a dramatic drop in bounce rates. They were making changes to the site layout around the time bounce rates suddenly dropped. I can see that they have Google Analytics installed twice on all pages. Could that be the problem?
If yes, why would having analytics installed twice cause the bounce rate to drop dramatically. Are the other site metrics reliable?
Any help would be much appreciated!

Yep, if you integrated any Facebook features around that time, there's a known FB bug that causes any visitor using Internet Explorer to re-load the page with "?fb_xd_fragment=" appended to the URL.
If you're being affected by this bug, you can look at behavior across browsers (FFX and Chrome are not affected by this bug), or you can search for URLs with that query string in them. The bug has been around for over a year, but FB has assigned it a P5, so not clear on when a definitive / easy fix is forthcoming.

Seems like a new post click overlay.
Thanks for the "next page" tip Greg!

Most likely something on your page is sending multiple calls/hits to Google. I've seen this happen with Facebook Connect. Look at the Navigation Summary report for pages that have this lower bounce rate to see if the "next page" is the same page (aka a self-referral). If so, that's your issue.
If you've started tracking Ajax interactions, that will also lower your bounce rate.

I've seen abnormally high bounce rates coming from a non 301 redirected domain before. Did you change the direction of any of your domains?
-
Ah! have you seen this?

No the data are site-wide, so the bounce rate has dropped on all pages. And the GA code is not installed twice. It's very strange.
-
Something accidental where you serve two pages? Or have your analytics twice on the page?

Hi Elias
Thanks for checking. I checked a bunch of other websites too, with no change.
And yes, the change is similar on all traffic sources.

Hi Thomas,
That's very odd! I've just checked some of our sites but none of them have seen anything like that.
As you haven't changed much in terms of layout then it would appear that there is a problem with your analytics tracking.
Is the change in bounce rate constant across all traffic searches i.e. search, direct etc?

Amazon referral on analytics
In the past month, I've received referrals from tt.amazon.com, coming from both Ireland and Germany - it made me a bit suspicious as I haven't seen tt.amazon before and I can't find much online about it. I'm a little reluctant to click through to the website in case it is suspicious... Does anyone know anything about this and should I be concerned? Thanks!

Self-Reffering Traffic After upgrading to Universal Analytics
Backstory: We have always had an issue with self-referring traffic but in waiting for the UA upgrade we put it on the backburner for getting fixed. We have now upgraded to UA and I was under the impression that GA would automatically exclude the domain associated with a property as a referral source. However this is not what I am seeing under my referral traffic source. With 10 websites having issues with this I need some help. Should I use the referral exclusion list? Also on a handful of our sites we have region specific URLs, I am also seeing these come in as self-referring traffic. I should also mention that about 85% of our sales are being attributed to the self-referring traffic. Here are two sites for example sake: ZootSports.com and K2snowboarding.com

Traffic drop after analytics troubles
Hi For two weeks we had an artifical low bouncerate & high pageviews/visit in our Analytics reporting. The day we corrected the bug in Analytics - our bouncerate & pageviews/visit returned to normal levels - however we saw our search traffic go down massively(-50% in sessions). The bug in the Analytics was caused by a second Analytics tag which was included in an external script which interfered with our own tag. The drop in traffic occurred just after the removal of the second script (which was only on our site for two weeks). We didn't touch our own tagging - and there were no technical changes on the site during this period, and there is no seasonal trend which could explain the sudden drop of traffic. We double checked our tagging - and the analytics tag is present & working on all the pages of our site. On the organic traffic report from analytics you can clearly see the when the troubles with analytics started & ended (artificial low bounce rate) - and that the traffic drop starts right after the reporting issue ended. Webmastertools also indicated a lower number of views/clicks, but not to the massive 50% drop. Is it possible that Google uses the measurements from Analytics for it's SERP's? Or should there be another reason, and where should we start looking? Appreciate your help! e5GmoMM

Switching Google Analytics from Urchin to GA
I want to finally make the switch from Urchin to GA in Analytics, but the Google support page is no longer working (I realize I'm late to this so they likely took it down/moved it to where I can't find it). I've been searching on Google but can't find a straightforward guide to changing that won't disrupt my data. Anyone have a link to a working guide, or can you provide some guidance?

Different metrics in analytics and adwords
Hi. My adwords campaigns and analaytics reports shows me slightly different results. Even for paused or disapproved ads in adwords, the analytics shows me some clicks?! I have automatic tracking enabled. Is it some kind of fault in configuration or its normal? Thank you for answer/link with answer.
