Wikipedia.org is a wiki encyclopedia, meaning that it is an encyclopedia with content created and maintained by its users. Wikipedia currently has over 7 million articles in over 200 different languages.
Wikipedia was launched on January 15, 2001 as spin off “feeder project” by Nupedia, a free internet encyclopedia. Nupedia became defunct and left the internet in 2003, but Wikipedia continued. The Wikimedia Foundation, a non profit organization, was founded on June 20, 2003 from Nupedia and the Wikipedia project, to oversee the Wikipedia Project.
The term Wikipedia was granted a U.S. Trademark on January 10, 2006. The European Union and Japan have also approved a trademark for the term.
edit How It Works
Wikipedia operates as a wiki, which is a site created and maintained by the site users. Anyone may edit articles on Wikipedia. Only registered users may create, delete, or merge articles. Registered users have certain of these permissions, as well as admin permissions, based on their level. The higher level users are elected, then they may appoint lower level users.
All edits are retained in the database, and users may view and compare older versions to the current article version to help them continually work together to improve the article. Edits are made live immediately, without a review process. The system relies on ongoing collaboration and editing to keep the articles accurate and up to date. In the case of a user who is abusing the system, the user can be banned.
One of the primary advantages Wikipedia holds over other encyclopedias is its up to date nature. Many articles on Wikipedia are updated within hours of a news break affecting the article. On the contrary, most normal encyclopedias take decades or at least years to get an update.
Wikipedia is also the world's largest encyclopedia ever compiled. It includes articles on many technical, specialized, or fluid topics other encyclopedias do not cover.
Debates and discussions are common on the accuracy and reliability of Wikipedia. The primary argument against the reliability of Wikipedia centers around the fact that Wikipedia articles are largely based on consensus rather than credentials. Several studies show Wikipedia is roughly as accurate as other encyclopedias. Wikipedia does require facts and statements be referenced for an article to meet its editorial standards. Adding the references is an ongoing work for the editors of Wikipedia.
Wikipedia has those who do not like it as well. Several sites discuss problems with the site including The Wikipedia Review and Wikipedia Problems. Complaints abound with anonymous editing, attacks by administrators, paid editing, and a lack of authority and fairness in actions by administrators, editors, and those in other positions working on the "encyclopedia."
Wikimedia Foundation, the organization that runs Wikipedia, covers the costs of operating Wikipedia primarily through private donations and fundraisers. Their January 2007 fundraiser netted over $1 million.

Home Page Analysis
Wikipedia.org Home Page Analysis Summary

The title and headings on the home page tell people and search
engines what a website is about.
Analyze the title & headings of the home page for free or the entire site.
Links & Images
Relevant links to other sites are good for people and search
engines. Images on a web page should be described for visually impaired
visitors and search engines.

Search Engine Friendliness
A few simple technical fixes can make any site show up better in
The title of a web page appears in search results as the link to that page. Learn more ...
The title of a web page appears as a clickable link in search results and bookmarks. A descriptive, compelling home page title with relevant keywords can increase the number of people visiting the site.
Search engines view the text of the title tag as a strong indication of what the page is about. Accurate keywords in the title tag can help the page rank better in search results.
A title tag should have fewer than 70 characters, including spaces. Major search engines won't display more than that.
The title tag of your home page (and any other page on your site) should not contain the site’s domain name or URL. These will appear near the title in search results, so use your 70 characters to tell people what the page is about. The title tag should not contain any HTML, because it will be displayed incorrectly or not at all.
- Good: This web page has a title tag.
- Problem: The title has fewer than three words. You may not be telling people and search engines enough about this page.
- The title of this site's home page:
The H1 heading is an important sentence or phrase on a web page that quickly and clearly tells people and search engines what they can expect to find there. Learn more ...
Just one H1
In most cases, a web page should have just one H1 heading. Using multiple H1 headings is okay if that is a logical way to organize the page, but they should be used sparingly. That’s because search engines can view multiple H1 headings as an attempt to signal that all the content on a page is equally important, a tactic that’s seen as an attempt to game the search engine algorithms.
Search engines look for an H1 heading to determine what a page is about. Human visitors do, too.
Content and placement
The H1 heading appears on the web page itself, unlike the page title, which people will see mostly in search results.
The H1 tag (which contains the H1 heading) is usually listed first among the other heading tags for a page. None of the major search engines, however, will penalize a site for listing H2 through H6 tags ahead of the H1 tag.
- Problem: This web page does not have an H1 heading. It should have one.

Your website's robots.txt file can tell search engines to ignore parts of your site. Learn more ...
Website owners usually use robots.txt to let search engines know which pages or sections of their site shouldn't be indexed for example, web contact forms, print versions of web pages and other content that's duplicated elsewhere on the site. Robots.txt can also be used to request that specific robots not index a site. For more information, read How To Use Robots.txt.
Search engine robots
You'll need to know the names of specific search engine robots - or "bots" – if you’re going to exclude any or all of them from any part of your site.
- Google’s bot is called Googlebot. Google is the world’s largest search engine, and is where many people discover new websites.
- Bing’s bot is called msnbot. Bing also provides search results to people using Yahoo to search the Web. Together, Bing and Yahoo are the second largest search resource, after Google.
- Baidu’s bot is called Baiduspider. Baidu is a major search engine in China, and the number of people using it is increasing rapidly.
- AboutUs.org’s bot is called AboutUsBot. To create a Site Report, AboutUs uses crawling technology that’s similar to what search engines use.
- Problem: You are blocking Google’s robot from indexing your site. It will not appear in Google’s search results. Google is the world’s largest search engine, and is where many people discover new websites. Google’s bot is called Googlebot.
This website can live at www.Wikipedia.org or Wikipedia.org. It's best for your site's visibility to live at just one URL, or web address. You'll want to create a 301 redirect to the URL you choose from the other URL. Learn more ...
Choose one or the other
If the same web page exists at two different URLs, people can choose to link to one or the other. Links from other sites to your website are valuable — they tell search engines that your site is important to people. By splitting valuable links between two identical pages, you're diluting the power of those links to help a page rank higher in search results.

- Good: Your website resides at www.Wikipedia.org, and Wikipedia.org is permanently redirected to it.
