Hi

Actually our bounce rate were 14% to 18% for more than a year, we haven’t done any thing except of one banner changes on the home page. Our bounce rate dramatically went to 50/60% on both direct and organic visitors ( even lots of visitors who come through searching our brand name has about 70/80% bounce rate which was less than 10% before).

Here is an overview

Direct visitor’s bounce rat = 34.77% currently while before it used to be 14 %
Google = 56.62% currently while before it used to be 14.37%
Yahoo = 66.86% currently while before it used to be 21.03%

etc

anyone has any experience with this issue, what could be the problem ?

many thanks in advance

HI IanTurner

no, because thats not a big changes .... just we have changed a banner

and let me tell also that the bounce rate increased after a sudden jump in direct visitors (around 1500 to 4000 etc). Before it we were getting around 1500 direct visitors while for 3 weeks we have been getting more than 3500 or like that.

but one more strange thing is that we are not just getting bounce rate on these direct visitors but also on organic ( Google + Yahoo etc), looks very very strange issue

any more helpful responses will be greatly appreciated !

thanks

Do you use any paid listings, for example Google Adwords?

Just wondering if it could be click fraud.

HI HelenDev

Yes we do, but Google analytics and Adwords admin shows normal visitors as of previous ….. actually only direct traffic has been increased and bounce rate has gone very high on both direct and Organic visitors.

We could say that the direct visitors are hitter etc, but even the bounce rate has been increased on organic visitors as well.

any more helpful replies would be greatly appric

Sounds like some sort of automated attack maybe? To skew your CTR and other statistics?

Anytime I see referrers with high bounce rates, I'll tend to try and backtrack where they are coming from. In some instances, I find that there are a whole bunch of references to the target URI sitting out there in a bunch of junk directories, MFA sites, garbitrage sites, etc.

Since 01.06.2008 until today, on a site with ~ 800 000 unique visiots/day, bounce rate is now +5%.
This figure was stable on the last year.

Same problems with time on site.

Something is wrong.

Has the overall number of visits increased, or just the proportion of bounces and direct traffic within the same number of visits?

Do you have any changes in pattern for the visitors' networks (IP address, organization)? Could

Is the banner any different, technically? For example was the old banner in a frame? Was it Flash while the new one is not? and so on. It's possible that your visitors' experience has not changed, but the recorded data has changed.

The the bounce rate change on exactly the same day (or the day after) you changed the banner?

Does the banner contain any indexable text that would cause your home page to be indexed differently? For example, some new vocabulary that might cause your site to have good ranks on irrelevant searches?

Your best clues for this might be in your organic search terms. Look at the terms that have brought people to the site before and after. Any big differences?

Also you should look more closely at your referrers. A visit can look like a direct visit if the visitor used IE but if they used Firefox the real referrer is usually not masked. If your analytics program allows you to isolate Firefox users, then look at that group for any significant new referrers that might be inappropriately sending irrelevant traffic to your site.

Lots of other things to check. I really doubt it's your banner, whatever it might be.

what exactly are you referring to by "bounce"? bouncing emails? customers registering but never activating their account? customers visiting but not registering?

sorry if that's a stupid question, but I only know about the email-related one.

I assumed it was "landing on the site and leaving without looking at anything beyond the landing page."

in which case and combined with the "huge" increase of visitors, might this not be another example of SV1 or 1813) ?

zahirshah, have you checked your log files for the user agent of these extra visitors ?

Make sure that these are real visitors first. My bet is that you are suffering a bad case of AVG link scanner and like millions of other webmasters your stats are being completely fouled up.

On one of my sites I have them redirected to their own site.

a) I don't care how they label my site
b) It gives them a taste of their own medicine ;o)

thanks for your replies guys

BUT still the problem not solved

we have noticed that one of “network location” which sends the false direct visitors mostly (the same network was sending around 1400 visitors while currently sends more then 2300), there are some more also, if a network location was sending 80 visitors before the same one is now sending 150 or like that.

now thing is that, the location which sends more visitors (1400 before while now 2300 one), there are more than half of visitors are real from that location, so we can’t block all of them. Or if we talk about to pick the particular IPs which has the bounce rate, that will take lots of time (and will not be an accurate way).

so any other solution how to detect it, how to know what would be the real problem, what if we change our hosting server etc ?

Any suggestion would be greatly appreciated guys

It is impossible to tell without further information from you, but others here are suggesting that your problem may be related to the new LinkScanner component in Grisoft's AVG anti-virus software.

The cause is AVG LinkScanner if your "bouncing visitors" have this user-agent:

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;1813)

If they don't, then the cause is something else.

HI Samizdata, thanks for your reply

Let suppose the cause is "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;1813)"

So how can I solve it, what should I do then?

OR is there any way to confirm if its the "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;1813)"

How can I detect it, where should I check it ?

many many thanks for the help

We don't know what analytics package you use, but as far as I am aware they all read the access logs to produce reports, and it is in the access logs that you would look for the AVG user-agent.

How you deal with it will depend on what package you use.

HI Samizdata

We use Google analytics if you are talking about it …… So how can we check the logs? Any procedure would be greatly appreciated?

thanks a lot Samizdata

Here is a quote from the thread I suggested you read:

If you use Google Analytics, I think you would set this up as a "Visitor Browser Program" filter

Presumably if you set the AVG user-agent to be filtered out you will see if the stats are any different, but I don't use any of these packages myself and cannot help you further.

You might otherwise ask your webhost how to access the raw log files.

From Google Analytics Support: "What is a filter?"

Exclude Pattern: This type of filter excludes log file lines (hits) that match the Filter Pattern. Matching lines are ignored in their entirety; for example, a filter that excludes Netscape will also exclude all other information in that log line, such as visitor, path, referral, and domain information.

A little research suggests creating a new profile:

Filter Type: Custom
Filter Field: Visitor Browser Program (possibly required, possibly not)
Filter Pattern: ;1813)

I haven't tried it myself but it should dispense with AVG LinkScanner.

At least until Grisoft is forced to change it.

HI, many thanks Samizdata ..... let me work on it ... actually i would not be able to do it ... but i will get it from my developer ! ... let see if he can do it or not ... i will let you know if the problem solved or not, thanks again

Please do, as I suspect it will be helpful to many webmasters.

If Google Analytics can't filter out AVG LinkScanner the bounce stats will be nonsense.

HI Samizdata and all here

I tried filtering

“Filter Type: Custom
Filter Field: Visitor Browser Program (possibly required, possibly not)
Filter Pattern: ;1813) and as well SV1

but still not solved :(

any other way to do it, our ranking and site performance really going down for a month now (I think its because of this rude bounce rate) …….. i heard that it has been happening with some other webmasters as well, any one here who is facing it, any one has any experience with it ?

many many thanks in advance

An interesting thought; one could argue that the AVG linkscanner isn't causing site performances to fall, it's only making them seem to fall by making it appear that bounce rates are higher than they really are. However, Google possibly takes bounce rates into consideration in working out site ranking. Now the higher the site is in the SERPs, the higher the perceived bounce rate will be thanks to this pesky programme. So three questions; can Google tell when a bounce rate is artificially inflated? Does a higher bounce rate push the site down the SERPs? Could this be a reason why so many high-performing sites have fell disastrously lately? Just my musings .....

I could find nothing on the official google blog about it.

At any rate, it occurs to me that AVG doesn't fetch images, and no hosted analytics solution (i.e. page tagged i.e. uses a gif request) solution would be affected by it. That would include Google Analytics.

Or is somebody seeing evidence to the contrary?

I've never seen a User Agent report in Google Analytics, is there one?
