Search Engine Optimization – Web Crawlers

BreakerBooks.com - Your breakthrough in ebooksThe terms web crawler, automatic indexers, bots, worms, web spiders, and web robots are programs or automated scripts with browse the World Wide Web in a methodical, automated manner. The term web crawler is the most commonly used term.

Web crawlers are a tool used for search engine optimization.

Search engines use web crawlers to provide up to date data and information. Web crawlers provide the requested information by creating copies of web pages that the search engine later processes. Once the information has been processed the search engines indexes the pages and are able to quickly download the pages during a search. The process of web crawling is a key factor in search engine optimization. Search engine optimization is the art and science of making web pages attractive to search engines. Computer people call the process of using a web crawler to rank a website spidering.

Some search engines use web crawlers for maintenance tasks. Web crawlers can also be used for harvesting e-mail addresses. The internet is a gaping ocean of information. In 2000, Lawrence and Giles manufactured a study that indicated the internet search engines have only indexed approximately sixteen percent of the Web. Web crawlers are designed to only download a tiny amount of the available pages. A miniscule sample of what the internet has to offer.

Search engines use web crawlers because they can fetch and sort data faster than a human could ever hope to. In an effort to maximize the download speed while decreasing the amount of times a webpage is repeated search engines use parallel web crawlers. Parallel web crawlers require a policy for reassigning new URLs. There are two ways to assign URLs. A dynamic assignment is what happens when a web crawler assigns a new URL dynamically. If there is a fixed rule stated from the beginning of the crawl that defines how to assign new URLs to the crawls it is called static assignment.

In order to operate at peak efficiency web crawlers have to have a highly optimized architecture.

URL nominalization is the process of modifying and standardizing a URL in a consistent manner. URL nomalization is sometimes called URL canonicalzation. Web crawlers usually use URL nomilization to avoid multiple crawling of a source.

In an attempt to attract the attention of web crawlers, and subsequently highly ranked, webmasters are constantly redesigning their websites. Many webmasters rely on key word searches. Web crawlers look for the location of keywords, the amount of keywords, and links.

If you are in the process of creating a website try to avoid frames. Some search engines have web crawlers that can not follow frames. Another thing some search engine are unable to read are pages via CGI or database -delivery, if possible try creating static pages and save the database for updates. Symbols in the URL can also confuse web crawlers. You can have the best website in the world and if a web crawler can’t read it probably won’t get the recognition and ranking it deserves.www.tgustore.com

How Title and Meta Tags are used for Search Engine Optimization

BreakerBooks.com - Your breakthrough in ebooksWhen it comes to title tags and search engine optimization there are a few question website owners typically ask. Does each individual web page need a different title? Is there a maximum length for title tags? Is there a title tag limit? Are title Meta tags a good idea?

The World Wide Web Consortium requires that every single HTML document must have a title element in the head section. They also state that the title element should be used to identify each individual pages content.

The title tag plays four separate roles on the internet.

The first role the title tag fulfills is what librarians, other webmasters, and directory editors use to link to other websites. A well written title tag is far more likely to get faster reviews then one that is sloppy or incomprehendable.

The title tag is what is displayed on the visitor’s browser. By displaying the title tag in the visitors browser the web user knows exactly where they are if they have to return to the site later on. Internet Explorer typically tires to display the first ninety-five characters of the title tag.

Search engines display the title tag as the most important piece of information available to web searchers.

A good title tag should be able to clearly indicate the webpage’s contents to the web user. A clear title tag is more likely to be placed in the user’s favorites list. The normal length for a good clear title tag is normally under sixty-five characters long. Title tags should be typed in the title case. Headers should also be typed in the title case.

When it comes to search engine optimization, the home page title is normally the first thing the web crawlers look at when they are ranking a webpage. Your website is introduced by your homepage title.

It is important to make sure that your title tag sounds credible.

Every single page of your website must have its very own unique title. A Meta tag is a special HTML tag that provides information about a web page. Meta tags do not affect the display of a webpage. Although Meta tags are placed directly into the HTML code, they are invisible to web users. Search engines use Meta tags to help correctly categorize a page. Meta tags are a critical part of search engine optimization.

It is important to remember that Meta tags are not a magic solution to making your website a raging success. The most valuable feature Meta tags offer to website owners is the ability to control (to a certain degree) how their web pages are described by the search engines. Meta tags can also let website owners prevent having their website indexed at all.

Meta tag keywords are a way to provide extra test for web crawler based search engines to index. While this is great in theory several of the major search engines have crawlers that ignore the HTML and focus entirely on the body of the webpage.
