Importance of search Engines: How Search Engines Work - Web Crawlers
It is the search engines that finally bring your website to the notice of prospective customers
. When a topic is typed for search, nearly instantly, the search engine will sift through the millions of pages it has indexed and present you with ones that match your topic. The searched matches are also ranked so that the most relevant ones come first.

Remember that a prospective customer will probably only look at the first 2-3 listings in the search results. So it does matter where your website appears in the search engine ranking.
Further, they all use one of the top 6-7 search engines and these search engines attract more visitors to websites than anything else. So finally it all depends on which search engines the customers use and how they rank your site.
the Keywords it very important
It is found by surveys that when customers want to find a website for information or to buy a product or service, they find their site in one of the following ways:
- The first option is they find their site through a search engine.
- Secondly, they find their site by clicking on a link from another website or page that relates to the topic in which they are interested.
- Occasionally, they find a site by hearing about it from a friend or reading an article.
Thus it’s obvious that the most popular way to find a site, by the search engine, represents more than 90% of online users. In other words, only 10% of the people looking for a website will use methods other than search engines.
All search engines employ a ranking algorithm and one of the main rules in a ranking algorithm is to check the location and frequency of keywords on a web page. Don’t forget that algorithm also give weightage to the link population (number of web pages linking to your site). When performed by a qualified, experienced search engine optimization consultant, your site for high search engine rankings really does work, unless you have a lot of money and can afford to pay the expert. With better knowledge of search engines and how they work, you can also do it on your own.
How Search Engines Work - Web Crawlers
It is the search engines that bring your website to the attention of potential customers. Therefore, it is better to know how search engines actually work and how they present information to customers who initiate a search.
There are basically two types of search engines: the first is by robots called crawlers or spiders.
Search engines use spiders to index websites. When you submit a website page by filling out the submission page required by the search engine, the search engine spiders index your entire site. A "spider" is an automated program run by the search engine's system. The spider visits the website, reads the actual content on the site, the site's meta tags, and also follows the links to which the site connects. The spiders then return all that information to a central repository where the data is indexed. The spider visits each link on your site and indexes those sites as well. Some spiders will only index a certain number of pages on your site, so try not to create a site with 500 pages!
Spiders will return to your site periodically to check for any information that has changed. The frequency of this is determined by the search engine moderators.
The spider is like a book containing a table of contents, actual content, links, and references to all the websites found during a search, and may index up to 1 million pages per day.
Examples are Excite, Lycos, AltaVista, and Google.
When you ask a search engine to find information, the search engine is actually indexing and searching, not actually searching the web. Not all search engines use the same algorithm to search their indexes, so rankings will vary from search engine to search engine.
