FAQ

Search engines like Google, measure and factor in the speed of web sites in their ranking algorithm. When they recommend a site they want to make sure users find what they’re looking for quickly. So in effect you and Google should have the same objective.

Speed is among the most significant success factors web sites face. In fact, your site’s speed directly affects your income (revenue) — it’s a fact. Some high traffic sites conducted research and uncovered the following:

Google.com: +500 ms (speed decrease) -> -20% traffic loss [1]
Yahoo.com: +400 ms (speed decrease) -> -5-9% full-page traffic loss (visitor left before the page finished loading) [2]
Amazon.com: +100 ms (speed decrease) -> -1% sales loss [1]

A thousandth of a second is not a long time, yet the impact is quite significant. Even if you’re not a large company (or just hope to become one), a loss is still a loss. W3 Total Cache is your solution for faster websites, happier visitors and better results.

Many of the other consequences of poor performance were discovered more than a decade ago:

Lower perceived credibility (Fogg et al. 2001)
Lower perceived quality (Bouch, Kuchinsky, and Bhatti 2000)
Increased user frustration (Ceaparu et al. 2004)
Increased blood pressure (Scheirer et al. 2002)
Reduced flow rates (Novak, Hoffman, and Yung 200)
Reduced conversion rates (Akamai 2007)
Increased exit rates (Nielsen 2000)
Are perceived as less interesting (Ramsay, Barbesi, and Preece 1998)
Are perceived as less attractive (Skadberg and Kimmel 2004)

There are a number of resources that have been documenting the role of performance in success on the web, W3 Total Cache exists to give you a framework to tune your application or site without having to do years of research.

First create an S3 account (unless using origin pull); it may take several hours for your account credentials to be functional. Next, you need to obtain your “Access key ID” and “Secret key” from the “Access Credentials” section of the “Security Credentials” page of “My Account.” Make sure the status is “active.” Next, make sure that “Amazon Simple Storage Service (Amazon S3)” is the selected “CDN type” on the “General Settings” tab, then save the changes. Now on the “Content Delivery Network Settings” tab enter your “Access key,” “Secret key” and enter a name (avoid special characters and spaces) for your bucket in the “Create a bucket” field by clicking the button of the same name. If using an existing bucket simply specify the bucket name in the “Bucket” field. Click the “Test S3 Upload” button and make sure that the test is successful, if not check your settings and try again. Save your settings.

Unless you wish to use CloudFront, you’re almost done, skip to the next paragraph if you’re using CloudFront. Go to the “General Settings” tab and click the “Enable” checkbox and save the settings to enable CDN functionality. Empty the cache for the changes to take effect. If preview mode is active you will need to “deploy” your changes for them to take effect.

To use CloudFront, perform all of the steps above, except select the “Amazon CloudFront” “CDN type” in the “Content Delivery Network” section of the “General Settings” tab. When creating a new bucket, the distribution ID will automatically be populated. Otherwise, proceed to the AWS Management Console and create a new distribution: select the S3 Bucket you created earlier as the “Origin,” enter a CNAME if you wish to add one or more to your DNS Zone. Make sure that “Distribution Status” is enabled and “State” is deployed. Now on “Content Delivery Network” tab of the plugin, copy the subdomain found in the AWS Management Console and enter the CNAME used for the distribution in the “CNAME” field.

You may optionally, specify up to 10 hostnames to use rather than the default hostname, doing so will improve the render performance of your site’s pages. Additional hostnames should also be specified in the settings for the distribution you’re using in the AWS Management Console.

Now go to the General tab and click the “Enable” checkbox and save the settings to enable CDN functionality and empty the cache for the changes to take effect. If preview mode is active you will need to “deploy” your changes for them to take effect.
