This is even more important since Google decided to include landing page load times in its Quality Score criteria earlier this year, meaning that advertisers pay more for poorly performing pages.

This means that you need to test the loading speed of your landing pages, to see if there are any issues you need to deal with.

AlertSite has just released a useful tool for AdWords advertisers to test the performance of landing pages. Simply type in the landing page URL, and you get a report which details response time, as in this example for gocompare:

As well as giving landing page load time, 1.7 seconds in the case of gocompare's ad, it also give details of the time it takes to redirect, as well as DNS lookup time.

So what if your landing page is too slow?

There are a number of steps you can take to improve page load time, as well as reducing your AdWords costs. Here are a few tips:

• Compress images
  
  This is a good way of losing a few kilobytes from your website and reducing the overall load time - compressing images can reduce the file size by 50% or more.
  
  
• Beware of Flash
  
  Your Flash powered landing page may be responsible for slow load times, and it makes it harder for the AdsBot to read your page, so removed any unecessary use of Flash.
  
  
• Avoid third party content on landing pages
  
  Putting third party content on a landing page can mean that a delay from any provider prevents the page from being fully loaded, and gives you a slower load time.
  
  This can include tracking tags from analytics providers or ads served via networks, so avoid this where possible.
  
  
• Use video content with caution
  
  As with using too many images, or Flash elements, video content may be useful for converting visitors but it can also slow load times.
