Understand Relationships Between Top Search Engines
Published March 19, 2010 | 
In the fierce competition between the top search engines, a lot of different methods are used to help the search engines achieve their planned market share goals, and while some top search engines are fed by other search engines, others just simply absorb other search engines. 
For example, Yahoo! owns AllTheWeb, Overture, and AltaVista, while it also owns and uses Inktomi’s technology and database for its partnering engines. Ask owns and uses crawlers and results of the Teoma engine, and DMOZ is owned by Netscape, while Lycos owns HotBot and Tripod, and these possible combinations and correlations allow some of top search engines to effectively compete for a share of the market and other search engines to fight to continue their operations.
Every top search engine, no matter what kind it is, is designed to provide people the most relevant information they search for, and you should arm yourself with the most current and important information to build the knowledge-base you need to climb to the most relevant and highly-ranked places of top search engines.
The Most Enjoyed Top Search Engines
Published March 14, 2010 | 
The top search engines are designed and in a constant state of improvement to do their best to provide the most relevant information, and we find it’s really interesting to find out which of them are ranked at the most popular. Statistics from one of the investigations of 2006 shows the following usage of top search Engines in the US:
- Google—42.7%.
- Yahoo!—28%.
- MSN—13.2%.
- AOL—7.6%.
- Ask—5.9%.
Other search engines in 2006 together possess 2.6% of all searching requests. This rate of top search engines in the US doesn’t correlate to activities of other countries’ or the world’s searches at all, but it could have something in common with them.
The search engine landscape continues to change and evolve, especially with the arrival of new players like Microsoft’s Bing, as evidenced by the latest statistics for 2010.
| 2010 | Yahoo! | Bing | Ask | Total | |
| 2010 02 | 71.35% | 14.60% | 9.56% | 2.55% | 98.06% |
| 2010 01 | 71.61% | 14.76% | 9.13% | 2.66% | 98.16% |
What is the Structure of Crawler-based Top Search Engines?
Published March 11, 2010 | The structure of top search engines is similar and consists of three main components, with the first is known as a Crawler or Spider, and it surfs the Web looking for changes such as pages that were recently created and any updates of already indexed pages. Spiders crawl through links on the Web, both inside the individual site and between websites, and if there is no site with a links to yours, the search engine spider will not visit your site unless you suggest the site yourself, which the majority top search engines allow.
The second component of crawler-based search engines is known as an Index, which gets the information gathered by search engine spiders. 
Think of the Index of crawler-based top search engines as a huge container that selectively concentrates the copies of all the pages found by spiders or crawlers that are identified and treated as relevant and worthy of being posted by top search engines, but even if crawlers or spiders visit your page, it doesn’t mean it will be indexed right away, and it could take for several weeks or months while waiting for you to resort to a “paid submission.”
The third top search engine’s component is Software, which scans the Index and then presents the consecutive list of the most relevant pages gathered on your search query. It is important to understand that every top search engine has its own algorithm, and the tuning of all search engine crawlers and spiders differs. If you decide to ultimately rank high at a top search engine, do not forget that the value will be given not by a person, but by a non-discerning search engine robot, which will not take into consideration and value the sophistication of the site design.
What are the Types of Top Search Engines?
Published March 10, 2010 | When we look at the world of the top search engines, it can be divided into Crawler-based, Human-powered, Hybrid, and Pay-per-performance search engines. Crawler-based or “traditional” utilize special software, and surf the Web to supplement their database. Search engine spiders scan parameters which are 
not visible to the human eye, and they don’t differentiate the amenities of design, but see only the code for images, which throws obstacles between it and your content. The most important data for search engine robots is the relevancy of your printed text, the frequency of your keywords and phrases in the contents of the page, especially at the beginning and the end of it, which should be emphasized. The top search engines of “traditional” kind are Google, Teoma, AllTheWeb, Alta Vista, and Hotbot.
Directories, which are also known as human-powered or edited search engines, do not look for websites to index them, but they rather prefer you take the action to suggest your site, and most of them have “Add URL” pages where you fill out the required information such as the website title, description, keywords, and email. You simply select the proper category for the website and then, in accordance of turn, it will be examined by human editors, leaving the decision of this editor only to accept or not to accept the site. So it is that human-powered search engines do not have their own algorithms to rank websites, they rank according to alphabetic sequence or Google Page Rank, and 
Directories are often used by top search engines as a source of new pages to scan for indexation, and finally, among the largest top search engines of human-edited nature there are Yahoo!, DMOZ, and Looksmart.
Hybrid Search engines utilize both types of listing, for example, MSN presents human-edited listings from Looksmart and crawler-based listings from its own Web crawler. Currently, some top search engines also resort to opposite listings such as Google and Yahoo, but it only takes a small part of the whole process, and they are still leading their classes. Also, there are meta-search engines, which work to combine the results from the number of other top search engines at the same time and present the results, and among this kind of search engines is MetaCrawler and Dogpile, for example, MetaCrawler compiles the results of seven search engines including AltaVista and Lycos.
In Pay-per-performance search engines, you pay for your site to be listed, re-spidered, and top-ranked according to keywords you both choose and bid on. It is important to note that there is not a big amount of sites focused only on paid inclusions, with the most prominent being Overture, and in addition you can find some additional paid services provided by other top search engines, but don’t feel obligated to use them.
