Common Search Engine principles

To understand  SEO you need to be aware of the architecture of search engines. They all contain the following main components:

Spider - a browser-like program that downloads web pages.

Crawler – a program that automatically follows all of the links on each web page.

Indexer - a program that analyzes web pages downloaded by the spider and the crawler.

HTML Sitemap for Users

HTML Sitemap has become a necessity for every person who own a static website which has some low number of pages, more likely not more than 100 or so and if your website has a lot more pages then you can show some important links on your sitemap like main categories or the pages that you think is important for the users and if you want to show all the pages on your HTML Sitemap then you can separate them in pages according to the priority of those pages.

What is XML Sitemap?

XML Sitemap, as it is clear from the name it is a kind of a map of your website written in XML language. This is made for robots, crawlers of search engines so that they can crawl your website with very ease and each of your URL can get indexed in search engines.

XML is easy for bots to read so they don't need to crawl your website and handle all of that difficult scripts to get to the new url, an XML sitemap gives it all what it needs and helps you to get good results.

Internal Ranking Factors in SEO

Several factors influence the position of a site in the search results. They can be divided into external and internal ranking factors. Internal ranking factors are those that are controlled by seo aware website owners (text, layout, etc.) and will be described next.

A Google sitemap is made in xml form, it is also called as XML sitemap, xml is the base language of crawlers and an xml sitemap is made of urls that are made of all the important urls of the website which you want to be crawled and indexed by google on priority basis.

Introduction – What Is SEO

Search Engine Optimisation is the process of choosing the most appropriate targeted keyword phrases related to your site and ensuring that this ranks your site highly in the search engine directories

From a search engine perspective, Search Engine Optimization (SEO)  is the process of making web pages easy to find, easy to crawl and easy to categorize.

History of search engines (SEO)

In the early days of Internet development, its users were a privileged minority and the amount of available information was relatively small. Access was mainly restricted to employees of various universities and laboratories who used it to access scientific information. In those days, the problem of finding information on the Internet was not nearly as critical as it is now.

Site directories were one of the first methods used to facilitate access to information resources on the network. Links to these resources were grouped by topic. Yahoo was the first project of this kind opened in April 1994. As the number of sites in the Yahoo directory inexorably increased, the developers of Yahoo made the directory searchable. Of course, it was not a search engine in its true form because searching was limited to those resources who’s listings were put into the directory. It did not actively seek out resources and the concept of seo was yet to arrive.

Such link directories have been used extensively in the past, but nowadays they have lost much of their popularity. The reason is simple – even modern directories with lots of resources only provide information on a tiny fraction of the Internet. For example, the largest directory on the network is currently DMOZ (or Open Directory Project). It contains information on about five million resources. Compare this with the Google search engine database containing more than eight billion documents.

The WebCrawler project started in 1994 and was the first full-featured search engine. The Lycos and AltaVista search engines appeared in 1995 and for many years Alta Vista was the major player in this field.

In 1997 Sergey Brin and Larry Page created Google as a research project at Stanford University. Google is now the most popular search engine in the world.

Currently, there are three leading international search engines – Google, Yahoo and MSN Search. They each have their own databases and search algorithms. Many other search engines use results originating from these three major search engines and the same seo expertise can be applied to all of them. For example, the AOL search engine (search.aol.com) uses the Google database while AltaVista, Lycos and AllTheWeb all use the Yahoo database.
