Is there a way not to serve ads to visitors who converted?

Using conversion optimizer with content network

[bcc1234]

Does anyone know if it's possible to disable ad serving to those visitors that tripped the conversion code?

For my campaign, it doesn't make sense to advertise the site to people who are already using it. No such thing as repeat orders or anything like that. So I'm looking for a way to limit "wasted" clicks from existing users.

I know that I can limit the number of impressions for visitor, but I do want my ads shown to the same person multiple times, but only until she converts.

Nevermind. I found something about negative audiences. I'm looking into it.

If it works like negative keywords, then I found what I'm looking for.

yep, on the display network, you can use a negative remarketing audience to accomplish that.

"For my campaign, it doesn't make sense to advertise the site to people who are already using it."
rarely true, imo. you may not want to show them the same messaging, but your past buyers are likely great referrers...

BCC,
That sounds interesting. Can you explain more how you eliminated showing ads to those who converted? I understand the use of Negative keyphrases, but not sure how to use it that way.

first, we need to clarify what an "audience" is...

an audience can be "interest based", a thematic approach to both positive and negative "audience" targeting (on the display network).

an audience can also be a "remarketing" audience, where you've put a defined AdWords remarketing code on a page, to tag people who visit that page.

so if you create a remarketing audience by putting the code on your receipt page, you are creating a targetable (positive or negative) "audience", and let's say you name that audience "already bought".

you can then use your "already bought" remarketing audience as a negative targeting audience for any campaigns in your account. to eliminate showing any display network campaign's ads, to those people who already bought, add the "already bought" remarketing audience as a negative audience.

once you start thinking it through, you can see the possibilities run deep... you might offer a coupon to first time buyers by negging "already bought"... you might offer special upsells to those same folks... you might target another very different product, because they bought and now know your name...

the system has some holes (cookies get deleted, people can opt out), but these holes are a small issue compared to what can be achieved. more details about the tracking (and its issues) here:

have fun!

in my head, i call it rethumping, not remarketing. :-)
