Search Marketing Blog by Tilak

Mostly websites are configured to serve the same content for www.domain.com; domain.com and www.domain.com/default.aspx (or index.html, index.asp, index.aspx). All three URLs will reach to same page of content. It could hurt your ranking in Google and other search engines because they will be indexed as three separate Urls. Google calls this process to “canonicalization”.

You may check out (using the Google Toolbar) the PageRank (PR) for www.domain.com, domain.com and www.domain.com/default.aspx – you will not get the same PR of all three URLs.

For resolve this issue you have to implement a 301 redirect from non-www version to www version or vice versa. For Apache server you can do 301 redirect via .htaccess easily and for IIS server you do also 301 redirect via web.config as well.

How to resolve default.aspx redirect problem?

1- always use http://www.domain.com instead of www.domain.com/default.aspx anywhere in your site, whether you are using absolute or relative links.

2- Put the javascript based redirect on your default.aspx page. This script will automaticall redirect to root folder of the site. Below is the simple javascript, which you put in your /default.aspx page:

<script type=”text/javascript”><!–
var u = ‘http://www.domain.com/’;
if (self.parent.frames.length != 0) self.parent.location=u;
if (self.location != u) self.location=u;
//–></script>

Technically search engines robots don’t process a client-based redirect, but if the /default.aspx URL never show in the address bar, then it should never get bookmarked or linked by anyone else.

Google has announced that Google Caffeine rollout has been completed, the new and improved web indexing system that now powers the world’s largest search engine. In August 2009 Caffeine was introduced for public. Google has explained just how their old index and Caffeine differ:

Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.

With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.

Here are some fun facts that Google shared as well:

• Every second Caffeine processes hundreds of thousands of pages in parallel. If this were a pile of paper it would grow three miles taller every second.
• Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day.
• You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles.

Finally Google has also introduced a feature that lets you put a picture on the Google home page. Bing has already received praise for its home page that shows a different picture each day. It hasn’t rolled out to yet but Marissa Mayer, Google’s VP Search Products & User Experience says this will appear for users throughout the world in the coming days.

You can personalized with your photo or image to the background of the Google homepage. You can find link “Change background image.” at the bottom left for uploading a photo. You can also use pictures you’ve uploaded to Google’s Picasa photo sharing site or those within a public gallery at Picasa.
