Search Engine Optimization or SEO is simply the act of manipulating the pages of your website to be easily accessible by search engine spiders so they can be easily spidered and indexed. A spider is a robot that search engines use to check millions of web pages very quickly and sort them by relevance. A page is indexed when it is spidered and deemed appropriate content to be placed in the search engines results for people to click on.
The art and science of understanding how search engines identify pages that are relevant to a query made by a visitor and designing marketing strategies based on this is called search engine optimization. Search engines offer the most cost effective mechanism to acquire “real” and “live” business leads. It is found that in most cases, search engine optimization delivers a better ROI than other forms such as online advertisements, e-mail marketing and newsletters, affiliate and pay per click advertising, and digital campaigns and promotions.
What On Earth Is An Algorithm?
Each search engine has something called an algorithm which is the formula that each search engine uses to evaluate web pages and determine their relevance and value when crawling them for possible inclusion in their search engine. A crawler is the robot that browses all of these pages for the search engine.
GOOGLE Algorithm Is Key
Google has a comprehensive and highly developed technology, a straightforward interface and a wide-ranging array of search tools which enable the users to easily access a variety of information online.
Google users can browse the web and find information in various languages, retrieve maps, stock quotes and read news, search for a long lost friend
using the phonebook listings available on Google for all of US cities and basically surf the 3 billion odd web pages on the internet!
Google boasts of having world‟s largest archive of Usenet messages, dating all the way back to 1981. Google‟s technology can be accessed from any conventional desktop PC as well as from various wireless platforms such as WAP and i-mode phones, handheld devices and other such Internet equipped gadgets.
Page Rank Based On Popularity
The web search technology offered by Google is often the technology of choice of the world‟s leading portals and websites. It has also benefited the advertisers with its unique advertising program that does not hamper the web surfing experience of its users but still brings revenues to the advertisers.
When you search for a particular keyword or a phrase, most of the search engines return a list of page in order of the number of times the keyword
or phrase appears on the website. Google web search technology involves the use of its indigenously designed Page Rank Technology and hypertext-matching analysis which makes several instantaneous calculations undertaken without any human intervention. Google‟s structural design also expands simultaneously as the internet expands.
Page Rank technology involves the use of an equation which comprises of millions of variables and terms and determines a factual measurement of the significance of web pages and is calculated by solving an equation of 500 million variables and more than 3 billion terms. Unlike some other search engines, Google does not calculate links, but utilizes the extensive link structure of the web as an organizational tool. When the link to a Page, let‟s say Page B is clicked from a Page A, then that click is attributed as a vote towards Page B on behalf of Page A.
Back Links Are Considered Popularity Votes
Quintessentially, Google calculates the importance of a page by the number of such „votes‟ it receives. Not only that, Google also assesses the importance of the pages that are involved in the voting process. Consequently, pages that are themselves ahead in ranking and are important in that way also help to make other pages important. One thing to note here is that Google‟s technology does not involve human intervention in anyway and
uses the inherent intelligence of the internet and its resources to determine the ranking and importance of any page.
Unlike its conventional counterparts, Google is a search engine which is hypertext-based. This means that it analyzes all the content on each web page and factors in fonts, subdivisions, and the exact positions of all terms on the page. Not only that, Google also evaluates the content of its nearest web pages. This policy of not disregarding any subject matter pays off in the end and enables Google to return results that are closest to user queries.
Google has a very simple 3-step procedure in handling a query submitted in its search box:
1. When the query is submitted and the enter key is pressed, the web server sends the query to the index servers. Index server is exactly what its name suggests. It consists of an index much like the index of a book which displays where is the particular page containing the queried term is located in the entire book.
2. After this, the query proceeds to the doc servers, and these servers actually retrieve the stored documents. Page descriptions or “snippets” are then generated to suitably describe each search result.
3. These results are then returned to the user in less than a one second! (Normally.)
“Approximately once a month, Google updates their index by recalculating the Page Ranks of each of the web pages that they have crawled. The period
during the update is known as the Google dance.”
Do You Know The GOOGLE Dance?
The Algorithm Shuffle
Because of the nature of Page Rank, the calculations need to be performed about 40 times and, because the index is so large, the calculations take several days to complete. During this period, the search results fluctuate; sometimes minute-by minute. It is because of these fluctuations that the term, Google Dance, was coined.
The dance usually takes place sometime during the last third of each month.
Google has two other servers that can be used for searching. The search results on them also change during the monthly update and they are part of
the Google dance.
For the rest of the month, fluctuations sometimes occur in the search results, but they should not be confused with the actual dance. They are due to
Google’s fresh crawl and to what is known “Everflux”.
Google has two other searchable servers apart from http://www.google.com. They are www2.google.com and www3.google.com. Most of the time, the results on all 3 servers are the same, but during the dance, they are different.
For most of the dance, the rankings that can be seen on www2 and www3 are the new rankings that will transfer to www when the dance is over. Even
though the calculations are done about 40 times, the final rankings can be seen from very early on. This is because, during the first few iterations, the
calculated figures merge to being close to their final figures.
You can see this with the Page Rank Calculator by checking the Data box and performing some calculations. After the first few iterations, the search results on www2 and www3 may still change, but only slightly.
During the dance, the results from www2 and www3 will sometimes show on the www server, but only briefly. Also, new results on www2 and www3 can disappear for short periods. At the end of the dance, the results on www will match those on www2 and www3.
GOOGLE Dance Tool
This Google Dance Tool allows you to check your rankings on all three tools www, www2 and www3 and on all 9 data centers simultaneously. The Google Web Directory works in combination of the Google Search Technology and the Netscape Open Directory Project which makes it possible to search the Internet organized by topic. Google displays the pages in order of the rank given to it using the Page Rank Technology. It not only searches the titles and descriptions of the websites, but searches the entire content of sites within are related category, which ultimately delivers a comprehensive search to the users. Google also has a fully functional web directory which categorizes all the searches in order.
Submitting your URL to Google
Google is primarily a fully-automatic search engine with no human-intervention involved in the search process. It utilizes robots known as „spiders‟ to crawl the web on a regular basis for new updates and new websites to be included in the Google Index. This robot software follows hyperlinks from site to site. Google does not require that you should submit your URL to its database for inclusion in the index, as it is done anyway automatically by the „spiders‟. However, manual submission of URL can be done by going to the Google website and clicking the related link. One important thing here is that Google does not accept payment of any sort for site submission or improving page rank of your website. Also, submitting your site through the Google website does not guarantee listing in the index.
Sometimes, a webmaster might program the server in such a way that it returns different content to Google than it returns to regular users, which is often done to misrepresent search engine rankings. This process is referred to as cloaking as it conceals the actual website and returns distorted web pages to search engines crawling the site. This can mislead users about what they’ll find when they click on a search result. Google highly disapproves of
any such practice and might place a ban on the website which is found guilty of cloaking.
