Google Adwords is making an important policy change starting April 1st. The display URL will have to match the landing page URL.

Now you can still use a tracking link, but the domain the visitor is finally redirected to must be the one that is the display URL.

Therefore, you might want to load up on some fresh web hosting accounts.

Dot 5 Hosting is a cheap one. I also use Bluehost, which is great because you can use addon domains and have up to 50 domains hosted on 1 account.

The importance of a display URL in an Adwords ad IS an important part of the ad, because it is almost like an extra line of text you can use in your ad, and if the keyword you are bidding on appears in the ad, you'll get noticed better because the keyword portion of the display URL will be bolded. That means a higher CTR and a lower CPC.

So for strong, tested, profitable Adwords campaigns, think about getting a specific inexpensive domain name and hosting account just for the ad. It could be worth it with the new Adwords rules.

By the way, if you don't track your links, you still can, and it's REALLY important. Otherwise you're just guessing. I use GoTryThis Black-Hat Version to track all of my links from 1 central location. Highly recommended. Comes in handy too if you want to switch affiliate programs on the fly.
