Don’t let advertising networks track you – Use the NAI Opt-out Tool

Well, if it weren’t for Google AdSense, TribalFusion, Kontera and other blog monetisation alternatives, the Internet would not exist the way it does today. We would not have seen such a blog explosion! Information is available free, thanks to the support which high-traffic websites & blogs get from such monetization programs.

Prevent advertising networks from tracking you

Most of such Network advertisers use cookies to track users’ Web preferences and characteristics and tailor ads for them. Based on this data they deliver the relevant ads to you! For instance, Google Dynamic Remarketing stores user search information in its DoubleClick cookie and pulls up targeted ads from its database and presents them before the users of the Internet.

The Network Advertising Initiative has tool called the NAI Opt-out Tool, which shows you which advertising networks are tracking your surfing habits via Cookies. It shows you which advertising networks have cookies on your computer, and lets you opt out of being tracked by them, should you wish to do so.

The NAI Opt-out Tool was developed in conjunction with its members for the express purpose of allowing consumers to “opt out” of the behavioral advertising delivered by the member companies.

Using the Tool, you can examine your computer to identify those member companies that have placed an advertising cookie file on your computer.

To opt out of an NAI member’s behavioral advertising program, simply check the box that corresponds to the company from which you wish to opt out.

Alternatively, you can check the box labeled “Select All” and each member’s opt-out box will be checked for you. Next click the “Submit” button. The Tool will automatically replace the specified advertising cookie(s) and verify your opt-out status.

If you ever delete the “opt-out cookie” from your browser, buy a new computer, or change Web browsers, you’ll need to perform the opt-out task again. It’s only when the network advertiser can read an “opt-out” cookie on your browser that it can know you have decided not to participate.

Effective August 1, 2009, the NAI has established a policy that all NAI member companies must implement a minimum five-year lifespan for their opt-out cookies, as soon as reasonably feasible.

Opting out of a network does not mean you will no longer receive online advertising. It only means that the network from which you opted out will no longer deliver ads tailored to your Web preferences and usage patterns.

    I tried the NAI Consumer Opt Out Protector Add-On for Firefox.

    As soon as the browser restarted of installing Firefox 3.6 locked up on the first command I gave it. I was able to get Firefox to run enough to get to the add-ons to disable NAI. The browser ran normally then.

    There seems to be a direct correlation between NAI running and Firefox not responding on my computer.

    I was able to opt out of most cookies on there site though and am thankful for that.

    I block all cookies except for the sites where I have log in accounts. My adware scanner keeps saying no adware was found. I may uninstall it soon. 🙂

    I also keep the Flash Cookie folders cleaned out everyday.

    Opera and Safari for Windows are the only two Windows browsers that don’t allow you to do this. I uninstalled them.

    I also use Advanced System Optomizer paid version.

    It seems that this is an interesting concept, hobbled in execution.

    Not only do we have to install the extension and restart Firefox but we then have to identify each domain that we wish to opt-out of. There is not a list of suggested candidates, so we are left to research each offending organization, one-by-one, get the correct URL and do it again, and again, and again…

    I uninstalled this crapware extension immediately.
