What is Tracking Cookie? All You Need To Know.

Guy McDowell 16-09-2009

celebrity-pictures-cookie-monster-stop-anytimeTo some degree, we’re all familiar with cookies as they relate to websites. Most of you are aware that they are out there and serve some purpose. Some of you know that websites use them to store information locally on your computer. There are also those cookies that track information about you and your web habits and report it back to the website that gave you the cookie.


Right about now, you may be thinking you don’t like that idea. Me neither. Yet, even worse are those cookies that track your activities, gather information and report it back to a website that you’ve never visited – a third-party website. The 2o7 cookie is one such cookie. What is this 2o7 cookie? Let’s take a look at it.

What is This 2o7 Cookie?

The 207 cookie is intended to track web usage and other information. The exact information that the cookie will track varies from user to user. The information is gathered and reported back to allegedly anonymously. Meaning, that it contains no information that can be used to identify that the information came from you.

This is hard to verify as there are many, many versions of the cookie. I’ll get into that in a second.

Who Made 2o7 Tracking CookieIt?

omniture A marketing firm called Omniture creates the cookies that report back to They do this on behalf of their customers, which include such heavy-hitters as eBay, Wal-Mart, Expedia and Ameritrade.  That’s why it’s hard to tell exactly what the cookie you have may be tracking. eBay will want different information than Ameritrade. One may be tracking the effectiveness of an e-mail campaign, while the other may be tracking their banner ad campaign.


Omniture set up the domain name as a way to maintain a degree of anonymity and to put the load of all these cookies onto a server that is used for nothing else. From a technology point of view, this is a good practice. From a public relations point of view, it’s a flipping disaster!

How Does this 2o7 Cookie System Work?

When you visit a site that is a client of Omniture, the site drops the cookie onto your computer. The cookie tracks the information it’s designed to track and sends it to the site. Now, Omnitrade does operate other domains that their cookies report to as well, but seems to be the most popular.

Omnitrade compiles the data into something meaningful and sends that information to their client. If that’s the case, then these cookies are relatively innocuous. However, some clients may also request to have that information sent to someone else as well. That’s where things get a bit colluded. Who are they sending it to? For what reason? Is it really anonymous?

Is the 2o7 Cookie Bad?

People that look at the cookies and see the part and then visit the domain would see nothing – a blank page. Then they would do a whois on the domain name and find that it is owned by Omniture. Not knowing who in hades Omniture was, things seemed, dare I say it, ominous? (Omniture does now have a page there that explains the generalities of the cookies.)


The other aspect to these cookies is they do take up resources. They do affect your Internet speeds and your computer speed. It may be an insignificant amount or it may bring you to a near-standstill.

Yet overall, cookies aren’t that bad. There are bad ones, but for the most part they are very helpful. They store information such as website preferences, login information and such, that make it easier to use many websites.

How Do I Stop the Cookie?

If you are still unsure about the 207 cookie, you can delete it and block 3rd party cookies from being set again. You do NOT need special software for this. Omniture does have a page that can help you with this, but guess what? Yep, it sets another cookie. The opt-out cookie only works for the browser and computer that you set it on. So if you use Firefox on your home computer, that’s the only one the opt-out cookie will block from

Here’s a small tutorial on how to block 3rd party cookies in Firefox, then in Internet Explorer.


How to Block 3rd Party Cookies Like 2o7 in Firefox

It’s pretty easy, yeah. Click on Tools in the top toolbar. Then click on Options. Just like below.

what is 2o7 cookie

When the Options window opens, click on the cute mask for Privacy, then uncheck the accept third-party cookies checkbox. Now, you will receive only cookies that report back to their originating site. Easy peasy!



Block Third-Party Cookies Like 2o7 in Internet Explorer

Pretty much the same as Firefox, really. Click on Tools in the menu bar, then click on Internet Options.


When the Internet Options window opens, click on the Privacy tab. Now you’ll see the slider. To block only 3rd party cookies, slide the slider to Low. Realistically, having it on Medium at the least is probably safer.

Now with all that done, you have no worries about the cookie. Sound good?

If this article helped you, I’d be glad to hear about it. If you know something more about cookie being more dangerous than I’ve described, let us and our readers know in the comments.

    THANKS for taking the time to expose the computing public to the smallest fragment of Big Data...if only they knew...

    1) the cookie is for an ad netowrk to serve you ads
    3) stop being paranoid
    4) I would rather have relevant ads sent to me than more ads for garbage
    5) this type of tracking enables efficient ad serving/behavioral targeting...if you disable this cookie then certain sites may not work properly, you inherently hurt the sites you visit that use this cookie, and you will be served VERY garbage-y ads

      I just use the Ad-Block add-on for Firefox, so I don't see any ads at all.
      Maybe someone works for Omniture? Hmmm? ;)

        I don't use any ads blocker because of what jupiterslove said. Using it hurts the sites you use and that's unfair.

          Really? Unfair? To quote my father,"Nobody promised you fair."

          There will always be far more people that don't use adblockers than do. Just as there will always be far more people that watch TV instead of recording it and editing out the commercials.

          Plus, if you think the ads are selling products, you're sadly mistaken. The ads are selling you to the companies that make the products. You are the product. I find that offensive. I pay for my Internet connection, my computer and my electricity. Then I have to see obnoxious ads everywhere I go? No thanks. That girl does NOT live anywhere near me nor does she think I'm sexy. Trust me, I checked. :P

          Yes, makes money from the ads and they pay me for the content I provide, and I am grateful for that. I'm sure you'll call me a hypocrite. However, just because the company I work for has chosen this business model, doesn't mean I'm bound to it.

          Well, rant over. Thank you for your patience.

          You pay for your internet connection, your computer and your electricity. But you don't pay to the websites, and they owe you nothing. They offer you to use their service while "suffering" their ads. Don't like it? Don't use it.

          when i visit B&N or amazon, i *am* paying them (a lot with the markup on international shipping), so why should i have to accept their *third party* (as in, not theirs) cookies too?

          sorry to post twice, but meant to add that if the purpose of 3rd party cookies is to target advertising, why do the ads always have internet dating (with some sexy vixen), enhancing one's, ahem, maleness, and such? i'm a 40+ long term married woman, so i find it offensive more than anything else.

          I just don't believe I have any moral, ethical or legal obligation to expose myself to the ads. Especially if they distract from the content. Nonetheless, my visit registers with their stats ware, so it benefits them in pitching their ad-space.

    Unless I'm missing something, I don't seem to be able to get rid of cookies, especially the 2o7 one, in Firefox. I've unchecked the "accept third party cookies" box and attempted to delete the list I see under the "show cookies" button but they all seem to pop back.

    When blocking on Firefox, you have to have the drop-down menu after "Privacy" set for "Use custom settings for history". Mine was on "Remember history", which had me fooled for a minute, as the window looks nothing like the screenshot.

    My Options>Privacy window doesn't look like yours at all. Using FF 3.5.3.

    you should use the firefox addons TACO (Targeted Advertising Cookie Opt-Out) which disables most behavioral advertising by setting permanent, generic, non personally identifiable "opt-out" cookies directly into the browser.

    The cookie is included.

    I just block at the network level. I have no cookies anywhere on my LAN. :)

    Although it showed nothing new (for me), the article is still very good, because it raises awareness about those tracking cookies.

    Thank you!

      You're welcome! I remember back in the day when cookies were a big issue, then they seemed to get ignored. Weird.

    ...or, arguably a better way, you can use the Firefox add-on AdBlock Plus along with the "EasyPrivacy" list seen here:

    That works very well for me, blocking this tracking cookie, along with many other such concerns!

    the trouble with blocking third party cookies is that is does impair the use of sites you don't mind accepting cookies from. for example, blocking third parties on your browser outright prohibits you from buying something on amazon or barnes & noble, until you set the browser to accept.

    that doesn't bother me, however. my question is: how to delete the yucky 2o7 cookie from the cookies folder? everytime i have tried i am unable to delete it and get an error message. is there a magic word?

      Interesting. Do you have administrative rights? Are you able to delete other cookies? If the answer is 'no', I'll have to think about the best way to go about deleting them. Or have the admin delete them.

      If the answer is 'yes', well, you might try going into the DOS command window and deleting it through there. Sometimes I can delete things like that, that I can't otherwise delete.

      Oh, if the browser is open, you may not be able to delete it as well - it's in use. Try closing the browser first. Get back to me, I'd love to help you.

        hi guy. i don't have full administrative rights - i use a ministry provided laptop for teachers. i can log in as an administrator, but it's not quite the same thing. i can delete other cookies though; i clean out my cookie file regularly, as i don't like to block outright for the reason i explained above.

        i will try the dos command window, and a couple of the other suggestions below as well, though i don't use firefox (chrome).

        i had a wee chuckle at "have your admin delete them". i can tell you don't work at a school!

        will check back over the weekend when i have an actual moment to sit down and think.

          Used to work at a college, I understand. Omniture may have some advice on their site about deleting the cookie too. Although, they'll probably just set another cookie.
