I want to send my paid traffic to separate landing pages based on whether they're US or international (so I can show them different payment options, different products, pricing, etc). Isn't there software for this? Something that reads where they are located and directs traffic based on that. Can I use
This feature is built into multiple trackers now but to be on the safe side, I’d recommend not using it directly from ad->landing page because it can be confused as cloaking.
Another option is to send everyone to the same lp and customize certain elements based on the geo.
Yup, as MrBaffoe mentioned, most trackers can handle this, but indeed, some traffic sources might see this as cloaking. But to be fair, I'm doing it quite often and didn't really get into much trouble, at least not yet. I had some campaigns rejected because of this, but no real trouble.
Then again, how do you plan to use this? It's not really the best idea to target severl GEOs with your campaigns, it makes the bidding ineffective as the prices per GEO vary a lot. You also can't use language specific banners etc ... Maybe if you give us more info, we can give you better advice.
