Paying for traffic is expensive.

There is nothing worse than sending traffic to a broken link or page that is down.

You would think this would be common sense, but at least once a month I click on a ppc ad that goes to a 404 page or a page with some other error code.

It happens to the best of us. We make a change to the website and forget to update the SEM campaign, or perhaps we typed in the wrong URL in the ad, or did some bulk editing and accidentally made a mistake.

When this happens, you are throwing money down the drain, literally!

This is most common with landing pages where you might make changes constantly, or launch new campaigns and take down old ones or simply redesign your site. There are lots of reasons why a landing page might not resolve…but, there is NO EXCUSE to be paying for clicks that you have no chance of converting. 

Hint: It is a good idea to turn your 404 page into a landing page. LeadPages.net offers a great 404 template in an easy to deploy format for WordPress sites.

If you are running traffic to dozens or hundreds of pages, it’s hard to know if one goes down.

Here’s a strategy you can follow to monitor your ppc for broken links to make sure your landing pages are always up and running.

There are two versions of this Adwords Script, one which monitors one account and another meant for MCC accounts where you can monitor multiple accounts simultaneously.

As you know, Adwords Scripts programmatically make changes to your Adwords account. While this script works wonders, it only checks your Adwords landing pages. If you happen to be using the same landing pages for Bing and Yahoo,  you’re covered…

I have my script running daily, and it basically checks all the URLs in active campaigns and emails me a report of all the accounts I run. Here is a screenshot of what my reports look like:

If you were to click through to see details, it would show you exactly where the problem links are so you can quickly go in and fix them ASAP.

If you want me to monitor your account for broken links for you, simply email me your Customer ID and once it’s linked in my MCC account, this script will automatically run it for you. You can email me at david@davidmelamed.com.

If you are more of a DIY kinda guy, here are step by step instructions:

Let’s dive right in. If you need to know how to setup an Adwords script follow the instructions in this post. There are only two small differences. One, you need to upload a different code for the script which will appear below and two, you will need to slightly modify this code to email you the report.

Great, now let’s setup the code to install. There are two options here. Google has a code they created and shared. You can try to implement it, however when I tried it, I got an error message, so I’m not sure how to fix it, but feel free to give it a try…

Good news if it doesn’t work for you though: Russ Savage published a code that works wonders. It installed super quick, and runs like a charm.
