When you run an experiment with Website Optimizer, you’re testing new content to see whether it improves your conversion rate. Google has added new feature that potentially makes this tool even more special by allowing you to automatically disable your under-performing experiments. Here’s a quick how to:

1. For newbies, or those of us who forget stuff. If your haven’t used Website Optimizer or want to refresh, here’s a quick tutorial.

2. Finding the new feature. Website Optimizer is a tool that can help you improve the effectiveness of your website in getting a return on your investment. By allowing you to test different versions of your site content, you can determine what will best attract users and lead them to convert on your site. If you use AdWords, the new feature is really easy to find as long as you use their standard interface. The Website Optimizer tab is right in front of you.

If you use the new beta interface, its just a tab different now. There is a new reporting tab and you can find the WO link by clicking the dropdown.

Click the Wesite Optimizer link and start to edit settings on whichever experiment you want.

3. Putting Website Optimizer to work on your experiments. With auto-disabling, Website Optimizer will automatically prune poor performing variations for you. This keeps overall conversion rate high while testing. Additionally, by removing poor variations automatically, your traffic is focused on only the variations that have a chance at winning, which means experiments should complete faster. Now you can have Google auto-disable poor performing variations you’re testing. Simply scroll down and change the off button to on, hover over the dropdown and choose conservative, moderate or aggressive.

Once you turn on this setting, it’s important to note that:

• Auto-disabling is available for any Website Optimizer experiment with more than two variations (i.e. you can’t use it for an A/B test, but you could for an A/B/C test).
• Any losing test that is automatically disabled will be removed from its experiment. It can’t be re-enabled again, so please read through the descriptions of the level of controls you can choose from before turning on the setting.

Google released a new keyword yesterday, named the Search-based Keyword Tool. With this new tool you can get a better knowledge on what your potential customers are searching for and which keywords you should advertise on your campaign.

Here’s the scoop: you know that the Google search engine starts with searches conducted by users and helps them find relevant pages. But for keyword targeting, what you want is a tool that goes in the opposite direction by starting with your pages and identifying keywords that potential customers are searching on to find your products or services. The Search-based Keyword Tool does exactly this, leveraging search query data relevant to your website’s content. In other words, this new tool gives you keywords that are highly relevant to your site but are not part of your AdWords campaigns. This helps you take advantage of missed opportunities.

The Search-based Keyword Tool is now available to all advertisers in the US and UK. IMO, this is perfect solution for those setting up their AdWords campaign and doesn’t know which keywords to start with.
