Google, the greatest search engine, maintains an index of all the pages that it crawls in the database. This index is updated or reformed after a rough time interval of about one month however the exact dates fluctuate and are not disclosed. The update process of this mega search engine is popularity known as the “Google Dance”. Google also happens to be one of the very few search engines offering free submission, and that is why it is having over 3.4 billion pages in its database. SEO industry seems to revolve around this giant engine as nearly 77% search results on internet are powered by Google. So it becomes extremely important for a webmaster to understand the process of Google dance in order to plan optimization for a website.

Every dance starts with a deep crawl that entrails spidering the whole web from the start which ends up to many days. Google uses around 15000 servers spread all over the world at its data centers. Obviously an index update cannot be proceeded on all those servers at the same time. One server after the other has to be updated with the new index. Servers used by Google are placed at data centers mainly located in US. It is possible for Google to record all queries centrally and then distribute them to the data centers but this would obviously be inefficient. During the Google Dance, the data centers do not receive the new index at the same time. One after the other the data centers receive the updated index. So if a user queries Google during the Google Dance, it is possible that he may get the results from a data center which still has the old index at one point of time and after a few minutes from a data center which has the new index because DNS is resolved to that latest data center.

Google Dance can be identified by querying the IP addresses of its data centers which are unique for every center. Generally all queries on the IP addresses of data centers are redirected to www.google.com but there are special domains by Google that resolve to these data centers individually. Those domain and IP addresses are

Domain IP Address
www-ex.google.com 216.239.33.100
www-fi.google.com 216.239.41.100
www-ab.google.com 216.239.51.100
www-in.google.com 216.239.53.100
www-zu.google.com 216.239.55.100
www-va.google.com 216.239.37.100
www-dc.google.com 216.239.39.100
www-cw.google.com 216.239.57.100

The process of updation of index can be seen by visiting these domains. The results at each center vary from one another which is a proof of the process going on. Also each domain mentioned above i.e www-xx.google.com has an additional domain www-xx2.google.com and the IP address of such a domain ends on .101 instead of .100. These pairs of domains belong to the same data center and hence search at these two pairs shows same results. Index updates at an individual data center seem be done at one point of time. Servers seem to update by one half first and during this first-half update time the remaining half of server becomes active and serves search results for queries. Once the half under progress completes it becomes active and serves the results and the other half undergoes the same process. Users are very unaware about the changes occurring behind Google and feel normal search experience.

Google has employed test domains www2.google.com and www3.google.com that resolve to a fixed IP address. This fixed IP address is of the data center that updates the index at the earliest. As soon as the dance starts least of these domains is assigned the IP of the data center that receives the very first updated index. So you can check for future Google listings (listings after update) on these test domains. Webmasters are eager to view the changes in position of their listings at these test domains. If everything goes fine then its time to change the DNS records at Google, if no problems are found then Google’s DNS is resolved to the data center that is updated at the earliest. However if certain problems arise then the update at other data centers is cancelled, now the domain google.com will not resolve the IP of the malfunctioning data center but it will resolve the previous index and hence general users are unable to get what is happening behind the scene.

However nobody can bet about the exact internal workings of Google but a technical overview like this one is all the way very necessary and helpful to plan an SEO campaign. Other than that it can also help webmasters and SEO experts in planning new developments & updates to be launched online by a certain date and time so as to be properly included in the search engine database. Now you know when and how to determine Google updates and do a lot to improve your rankings.

Google Operating System point out something interesting in Google’s algorithm recently: a preference in favoring recent content.

The example provided would seem to favor the conclusion; TCP/IP’s anniversary today has resulted in Google preferencing recent posts, including from Digg, over informative articles related to the search term such as Wikipedia who would have normally had the top or near to the top position.

Indexing recent posts has been a strength for Google, to the point that at least for areas like Blog Search they’ve become the defacto standard as others such as Technorati have struggled to keep up. That Google would preference recent posts in its search results without the usual incoming authority links throws out the rules we’ve always known with Google, and I’m not sure if this is a good thing or bad thing. It would depend a lot on the results, but it would limit attempts to game Google results through incoming links. Perhaps it’s the first step towards Google embracing Web 3.0 with semantic search that learns as it goes, constantly updating its results to suit the user at the time they are searching, complete with contextual awareness as well.

You have probably heard of link popularity but ! what is the real value of content in the view of search engines ? if you would like to know then take a look at the title of this article CONTENT IS KING on search engine ranking ! there is nothing more valuable then content .

Content does not only bring you traffic but also encourage people to link to your site without asking for it ! that is the truth , if you have unique content then you are in the right track . regarding content you always have to remember never – ever brake the copy right issues as well as never using the dublicated content cause it is not going to help but hurts your site. avoid the “tricks” and go for legitimate content. Set your page up correctly and a few hundred words of solid content will do more than any secret techniques. Leave the tricks to the magicians ! you have to always watch your head that means never use doorway pages , These days, you might still get away with it for a while; however, there’s a good chance that you’ll eventually get caught. Once you do, your doorway domain as well as your main site stands a chance of being penalized or even banned. these sneaky doorway domain techniques have become so prevalent over the years that the search engines (especially Google) are really starting to crack down on it. It doesn’t matter if your doorway domain has totally different content from your main site. The content of an *extra* domain is not considered to be unique, and would be classified as spam by nearly every engine.

How to Enhance your Blog’s SEO and Attract Relevant Traffic in One Easy Step
Posted by: Aaron Brazell
The constant war to optimize a blog for traffic and gain new visitors is one that any serious blogger understands. I’m about to tell you a trick that I’ve been experimenting with for the past month and have seen pretty good results from. So listen up.

One of the rules of SEO is to keep external links relevant. That means that if this site is about blogging and new media, links to sites discussing blogging and new media are better for me than links to sites about… cats. The other unwritten rule is that every blogger who uses WordPress looks at his dashboard for new inbound links. Of course, there’s the Google search or Technorati search that can do the same thing, but WordPress users have it easy and new inbound links are listed in the dashboard for easy reference.

So leveraging these two rules, we can take one step and improve traffic flow and enhance your blogs SEO – and it can be done on any blog.

First off, go to Technorati or Google Blog Search (I like the latter for speed) and do a search for a relevant search term or phrase. For the last month, I relied on Technorati for the search term WordPress 2.1. I used this term because I wanted to monitor discussion surrounding WordPress after 2.1 had been launched. Now, I use Google blog search to search for the phrase new media blogging. Much more relevant to a greater part of my blog.

Now, having made the search, you can grab the RSS feed for use on your blog. If you’re using WordPress widgets or WordPress.com, you’ll want to make sure you’re grabbing the RSS feed and not the Atom feed.

Now, using whichever sidebar RSS aggregator you wish (again, WordPress.com has widgets and you can find similar functionality for WordPress, TypePad, MovableType or Blogger), use the feed from the search to parse out headlines into your blog sidebar.

Now you might wonder if this is considered spamming and the answer is no. First off, only use headlines. Do NOT produce full content. Make sure that your implementation includes a link back to the source blog. Generally, this is done by making the headline a link. This link will be visible to the source blogs and may attract them to your site. In addition, because your search is a relevant search based on the topic of your blog, search engines will consider your links higher than non-relevant links.

In essence, this one step will not necessarily serve your current readers, but will attract new ones based on curiosity of “who’s linking to me?”. This has had positive results for me. My traffic continues to climb, feed subscribers continue to grow and my Technorati ranking is approaching 2000. Let me know how this trick fares for you.

Some might not help wondering about the heavy dependence of those that are doing business on the Internet on search engine optimizing (SEO) marketing. Especially some cannot help being miffed when they found out that there are business people that are trying to do business online by using SEO only. It is not only unfortunate, but from what is taking place there is something wrong with such an outlook, and if there is anyone who will pay the price it is the businesses that are letting business opportunities slip through their fingers.

If someone wants to open shop offline in a brick-and-mortar setup and does not want to pay rent, it is as good as joining a different batch of business people that are doing business using different methods. It is difficult to say which is right or wrong, because we all know that some had become successful by selling form their trunks, and except enduring the inconvenience, it is possible to make money. It is known that most startups are strapped for cash and they start doing what they are doing with a shoe string budget. If SEO is catering to such startup entrepreneurs, they are doing a lot of service to society.

However, if businesses with the money and sustainable sales turnover start contemplating to be dependent solely on what SEO could offer, they would be wasting their time. Because, the cost of paying for advertising like Pay Per Click (PPC) has become very affordable and if they are not taking advantage of it, they are definitely shooting themselves in the foot. Because SEO can never cut it for many businesses. It gets even more demeaning if business people start paying thousands of dollar to have their site optimized to get a good spot on the search results, in order to drive more traffic to their site. Because, SEO cannot do that, and even if it does it takes time. It is difficult to keep any good position attained on search results for the long haul, which means it will continue to be a drain on a budget.
