PS – used tweetmem simply as an example. Don’t even know if they store a cookie or not – just know that the javascript code you get opens up an iframe to their site on your.

Thanks Richard – you’re a star – much clearer to me now.

I appreciate your time in answering these questions.

All the best,

Yep – AFAIK the iframe will be considered a separate window and domain, but I’m not familiar with tweetmeme, so that cookie may actually be first party. Would take some digging to find out TBH. I’d say that there are some security issues that preclude data being passed between the parent and iframe.

Hi Richard, I realise my question was a bit vague (perhaps because I was confused a bit myself )

As to the analytics – makes sense. Thanks.

On the iframe, if a piece of javascript opens up an iframe on your page (e.g. – the tweetmeme javascript code). Does that mean that the tweetmeme cookie (if there is one) would not be treated as a third party cookie when someone browses onto a site containing it?

Essentially, an iframe is simply another window, isn’t it – as if it were a page on its own?

Regards,
Ricardo

Hi Ricardo

Most analytics providers, including Google Analytics, use first-party cookies. The GA cookie belongs to your domain, so it’s first-party.

I’m not 100% sure what it is you’re asking, but if I’m right then I think the way to remove your own traffic from GA is to use a filter.

Blocking 3rd party cookies actually happens in the browser – you cant do anything as a site-owner/webmaster.

The iframe idea wont associate the cookie with the site in the main frame, so I’m not sure if I’m following this last bit TBH?

Hi Richard – the comment is a bit late in coming – I hope you don’t mind.

I actually have a question as to the blocking of third party cookies and Google analytics.

Are analytics cookies “third-party” cookies (I think so)? If so, what would you recommend as an option to block one’s own traffic to one’s own site (I currently use a filter with a cookie).

Would it be enough to:
1. create the filter
2. visit your site with all cookies allowed
3. and then have third party cookies blocked at which point all existing will be kept?

Also, would this result in people being logged as “unique visitors” each time they visit if 3rd Party cookies are being blocked by them?

And, lastly (shew!), what if a piece of javascript opens an iframe in a page (white-hat) and cookies get stored by a third-party – I guess these wouldn’t be blocked as “third-party” cookies, would they?

OK, a real mouthful – hope you don’t mind!

Regards,
Ricardo

Hi Gregor,
well i think that barier it’s a good thing for a website. try accesing some important sale website without cookies enabled.see what u get back.

Richard, still tried to reproduce that. Couldn’t yet.
Cheers mates

I’d say that a user not having cookies allowed isn’t a good enough reason to put a huge barrier in front of them.

Like you say, more and more people are disabling cookies so web developers need to be able to cater for them – not just put a huge sign up saying you can’t get past until you change something.

Hi rika

Seems either my problem was a fluke, or this has since been resolved. I’m quite sure my cookies were active when this happened, but I’m also unable to replicate now.

Thanks for dropping by and commenting
