The actual state of affairs shows that your good looking site doesnít interest Internet search engines until you use important and vital for optimization rules and techniques, so starting when building and optimizing a website, itís very important to get a notion of how search engines work, what their goals are, and how they learn. Trying to follow experienced person or adopt a decision about some tricks without comprehension can harm you.
Itís a well-known fact that search portals strive to improve the quality of their search results. Historical development of Internet search engines ranking starts from the logic of an ordinary Web surfer and attention to keyword distribution. Later, other factors prevailed, among them ďlink popularity,Ē which remains a huge factor in ranking. Both of the above mentioned parameters as well as distinguished search engines ranking factors form our optimization strategy on website building stage and later on during popularity establishing, increasing traffic, and service, and resources development.
Therefore, the start of the project or site development process will be closely connected with understanding of Internet search engines explained features and ranking strategies.
While explaining Internet search engines particulars, we should begin form the notion itself. A search engine is a searchable online database of Internet resources. It has several components: search engine software, spider software, an index (database), and a relevancy algorithm (rules for ranking). The search engine software consists of a server or a collection of servers dedicated to indexing Internet webpages, storing the results, and returning lists of pages to match user queries. The spidering software constantly crawls the Web, collecting webpage data for the index. The index is a database for storing the data.
Internet Search Engines Explained
We should also mention four main types while describing Internet search engines. They are crawler-based (traditional or common engines), directories (human-edited catalogs), hybrid engines which are META engines and those using other enginesí results, and paid listings (PPC and paid inclusion engines).
As you can see, spider software belongs to crawler-based Internet search engines. In a nutshell, their work is as following: spiders read your page, index, and rank it. Finally, it appears on search engine results pages for the words and phrases most common on the indexed webpage.
If youíll look on the way result listing is generated more closely, you can clearly differentiate pure search engines and directories (For example, the latter group is often mistakenly called search engines, too).
Directories work in the following way: you have to submit your pages manually to one of the existing categories, your site is visited and read by a directory editor. You must be ready for long queue process as reviewing by an editor (directories use human power for indexing) takes much longer to process all pages. Most directories do not have their own ranking mechanism; they use some obvious factor to sort the URLs such as an alphabetic sequence or Google Page Rank.
Paid inclusion engines require certain fees to list your page with some differences in the working system as re-spidering or top-ranking for keywords that you choose. Moreover, most major Internet search Engines utilize such schemes as a part of their indexing and ranking system. PPC engines use an auction system where keywords and phrases are associated with a cost-per-click (CPC) fee. The fundamental principle that lies at the heart of PPC process is that the higher you bid, the higher your position will be for the particular search terms.
The significance of major Internet search engines is explained in detail in our next sections. Without knowledge of ranking algorithms and the way result listing is generated, most your work can be idle or not visible for search engines. In other words, the siteís design is meaningless if your pages are ranked low on Internet search engines.
It should be noted that search engines now apply a sophisticated technique to determine how relevant you pages are to search words and phrases. For this purpose, they examine many on-the-page and off-the-page factors and only after this give your page a certain position or rank. This position will be visible while displaying results for a certain search query. To be top ranked, you should also be familiar with such parameter as relevancy of your website. It means that your content should depict a particular subject and be focused on it.
In conclusion, if youíre working for highly ranking website, continuing to optimize your pages over time, the most important lesson you can learn is that internet Search Engines are striving to live and actively use their everyday experience to change for the better. Thatís why when considering any trick and tactic for your search engine optimization strategy, you must think about goals of the engines. Will it give you better results applying to most searches? Start reading and understanding what will be sound for your project. Internet search engines explained algorithms and features will guide you to peaks of ranking.
Spider-based search engines have made their way from simple, spam-vulnerable algorithms to complex and sophisticated mechanisms that are dangerous to play with. Also, the search engine optimization industry has developed a number of black-hat techniques to abuse the automatic site indexation and ranking. These techniques are referred to as search engine spamming. Nowadays, they can be considered neither legitimate nor effective.
