Cuil search engine was released ealier from estimated time, their claimed that already have indexed around 120 billion sites, more than Google and others search engine did. Cuil direction board including three of Google former employees said that Cuil will be Google best competitor. One thing to be compared between Google and Cuil is the number of indexed pages, and the search result relevance as the main idea.

Cuil is one good search engine, but it seems that Cuil is not has search result as deeper as Google, and even the result is not so relevance as Google has. When you type dog on Cuil search engine, then it will shows 280 millions result, and Google reach 498 millions. Regardless relevance of search result is subjective, but Google put Wikipedia at the first place, than dog.com site. In contrary, Cuil put dog.com on the first place then Wikipedia. Both of them give the same result, but Google much better.

Techcrunch.com made comparison Cuil vs Google, they put Apple, France, Stonehenge, Silicon Valley in sequence, and the result is:

It is clearly Google has indexed much more than Cuil has done. Furthermore, Cuil result rank is not better than Google based on the same question. But, things to be considered is, Cuil just begin their search engine, while Google need one decade to built the powerful search engine.

Search Engine

Search Engine General Principle

To know further concerning this search engine performance, there are some things need to talk first, especially related to architecture problem and mechanism of the search engine.

Spider

Is the program that downloads the pages they find, spider looks like browser. Its difference is at browser directly presents the information (picture, text, etc) for the people need at that moment. While spider isn’t do that to present in the form which is seen like that, because its interest is for machine not for human, even spider is run by machine automatically. Its interest is to take the visited pages to be kept into the database owned by search engine.

Crawler

Is the program owned by search engine to trace and find link which is from each pages met. Its duty is to determine spider have to go where and evaluate link according to the early determined address. Crawler follows link and try to find the unheard document by search engine.

Indexer

This component do activity to elaborate each pages and check various element, such as text, headers, structure or write style feature, special HTML tag, etc.

Database

Is the standard place to saves data from pages which have been visited, downloaded and have been analyzed, once in a while referred with index from search engine.

Result Engine

The machine does the classification and rank determination from search result at search engine. This machine determines which page met best criteria from search result by user request, and how the appearance will be presented.

This process is done based on ranking algorithm owned by search engine. According to the page ranking method used by them are their rights, researchers has been studying the nature which they use, especially to improve the search result by that search engine.

Web Server

Is computer serving request and give reply from that request. These web servers usually produce the information or document in HTML form. On the page is available service to fill in the search keyword wanted by user. This web server also responsible to sent over search result which is asked to the computer that ask for the information.

Way The Search Engine Work

Search engine such as many we are known, not really do search to the entire World Wide Web directly. Search is done through databases which save text from each page outside there. Text from each pages are kept into their database server.

When you do the web search by using search engine, actually it searches the copy page which is kept in their database that contains the copy page at the last time they are visited. When you click provided link in the search result page done by search engine, the fact is the address given from server search engine through actual version in their database.

Database on the search engine selected and classify by robot program which is called spider. Though they analyze the page will be taken and kept into their database, in reality can be said that they take it from one place.

Then to find the other potential page, they relate to links on their pages which have been kept in their database. This machine cannot write down URL and think the pages will them to try to visit. Computer truly sophisticated more and more, but they just cannot think creative as like as human in general.

If a web page have never been linked from other page, then search engine spider will not find the page, they are only watch from their database.

To sites that are really new, and there is no other site which make their link to the newly site, it’s absolutely sure the spider will not know it. Way to make the newly site can be enlist at search engine, specially to site which is not linked yet by another site, is by giving the direct notification to the search engine that there is new site, this is done by human. Most of all search engines give the facility or offer for this matter.

After spider finds a page, they will send the invention result to other computer to be indexed. This program identify the text, link and other content on the page, then save it into their database file, so that through the database can be done the keyword search or anything in advanced which they offer, till you find one site which match with your desire.

Some types of page and link are not packed into most search engine because some reasons. Some the others nor entered because spider cannot access the page. The page which is not packed into the index referred with “invisible web”, where you cannot directly see the page. There are large numbers of this kind of page, it reaches bigger than the page may be presented.

Hidden Page

Page may be peeped out from search result at search engine referred with “visible web”, while the page may not be peeped out or cannot be seen, because some rules, either on the site owner request, or because something else, then referred to “invisible web”. First version of this invisible webpage begin to be hot topic since 2000, when at that moment there are many pages was not presented by search result, so that technically arranged and created special procedure that capable to handle that problems.

In this time there are some page types use this facility, the page cannot be seen but creates in such a manner to be in webpage so that can available. The types are:

1. Page with non HTML form, such as PDF, Word, Excel, Corell Suite, etc, these documents are translated into HTML form, so that in this time most of popular search engine can present the translation result.
2. Page base on script that is link with special symbols in language program form, this matter have been handled and almost all search engine have this ability.
3. Dynamic form page through program that create database (like Active Server Pages, Cold Fusion, PHP, etc) could be indexed when it has stable/fix URL that could be found by search engine.

Why be Hidden?

There still some restriction for search engine to search for invisible file, so that search engine cannot give the search result.

1. Search engine still not thought this solution yet. If one page want to go to another page need type process, then it is restriction for the search engine, because machine cannot do it. They cannot do searching to catalog, they cannot fill login or password, etc.
2. Page that asked not to be indexed by search engine. For this matter, search engine do this pursuant to rules which have been specified. There no technical reason for this matter, every sites owner or search engine owner have ability for not to index their pages if they wish that way.

Google Adsense, is an very popular affiliation program for online internet business in the world this time. Everybody can participate to become the advertiser for google on easy condition, only by placing the google advertisement in their site. With commission method pay per click (PPC), the method to make money from google much more simple and very liquid, difference with other affiliation, which oblige to sell something then get the commission. Google Adsense have brought the new revolution in internet business, this program have made the online millionaire without having to look for the big investors as done by dot com companies from Silicon Valley.

What Google Adwords and Google Adsense are, before know farther about Google Adsense, will be commented Google Adwords first which is the beginning of Google Adsense. Google Adwords is the advertisement program which is offered by google to site owners which wish to promote their sites, by presenting advertiser site link in search result for selected keyword.

Example: if we do the search in google with keyword welding for example, then besides search result, at a quarter part on the right will emerge Sponsored Link / Sponsor Message.

Of course, advertisers will be imposed a number of expenses depended from popular selected keyword.

Picture 1. Sample search result with Google, Google Adwords advertisement in wide a quarter on the right side (pay for), which is left side free of charge.

But Google realize, though they become first search engine in world right now, not all internet users in the world use google as search machine, so that advertisement in google adwords, can not reach entire internet consumer yet, therefore they offer to site owner to install the google adwords advertisement in their site with share holder method called Google Adsense (see the picture of 2). If there is someone visit adsense participant site and click the advertisement in their site, then site owner will get commission from google, this commission payment method like this actually referred Pay Per Click (PPC).

Picture 2. advertisement appearance at the adsense participant site.

How many commissions accepted?

Commission which is got depends on the advertisement placed in our site. Google will place the advertisement according to site content. Pay per click price is determined by how much the keyword cost which is esteemed by Adwords advertiser, for example welding keyword possibly is merely esteemed 0.5 dollar per click, but insurance keyword for example can be esteemed till 30 dollar per click. This high valuable keywords referred with High Paying Keyword (HPK). Sites with specific topic for particular keyword referred niche site.

(example in picture 2, niche site www.welding-engineering.com with welding topic).

Imagine when we can make site which is visited by 1000 people per day, and assume 10% which click the advertisement with commission 1 dollar per click, then in one day that site have made 100 dollar per day or 3000 dollar per month. Pretty fair, isn’t it…Assumed we have 10 similar sites, calculate by yourself that commission.

In America, many people have got hundred of thousand even million dollar, like plentyoffish.com or digg.com or ezinearticles.com, the excitement part is their sites not begin from big companies silicon valley (like yahoo, google, etc), but from home, yea those are from home with PC which is connected to internet.

How To Participate In Google Adsense Program?

From the description I mention above, of course to join into this program, we must have site to put the advertisement on, when trading, site is shop, and advertisement is the thing to trade of. After having site with particular niche (e.g. education, consultant, farm, etc), we can sign up in google.com/adsense , register first, then our site will be reviewed by google, when this site fulfill their standard and accepted, google will give the html codes that we can put in our site. Finish … simple isn’t it…?

Eiits… wait a moment, what if don’t understand to make site… ? .. don’t worry, for beginner just make blog (surely a lot people have known), blog also able to be attached adsense.

For beginner, these are following steps to make adsense blog (process not more than one hour):

1. Determine blog topic to be made (for example : self development. music, education. etc).

Create blog in blogger.com, why have to blogger, because blogger is owned by google, so easier to approve, if you have been an expert, you can use other.

2. Find article with similar topic with your blog, (just search in google), make article post in blog at least 10-15 posts, then apply to join adsense program via google.com/adsense

3. After accepted, we get an account which is contents can use to view click report and commission, also html codes which can be paste to our site. For blogger, it’s easy to put the codes in, just add page element, then click add html/javascript, copy adsense code there. Finish.

remark : for time approval from google, depended to the site, can be approved directly, or one day even more.

There are some kinds of advertisement type in google, but which is used in common is adsense for content and adsense for search (see the picture of 2).

Supposing to sell, the shop already made, there are thing to sell, now what to do?… yeah we just have to find the buyer, this is the phase rather heavy and need time. It is Useless to have shop without buyers. In this case, Buyer is our site visitor, or in internet called traffic.

More and more traffic, it means much possibility the click on advertisement and more and more we accept commissions.

So for this matter, how to improve traffic to our site, generally there are many ways of to get traffic, one of the example is to get free traffic through search engine. Let us back to early discussion, if we type the welding keyword in google, there are more than 30 million search result (picture 1). Which is have more possibility opened by visitors? The answer is the first page. If our site appear on the first page, it will be very good, second or third page still OK, but how if on page 20?… who do will see :)..

Of course all adsenser wish their niche site will appear on the early page in search result in google, how to make our site appear onthe early page?.. The answer is with Search engine Optimization (SEO), what is that SEO, I will explain it in the next article.
