Absolute Link – An absolute link is a hyperlink that includes the complete URL, which is the domain name, folder or subdirectory name and file name. For example: http://www.pro-seo.com/tutorials/optimizationbasics.html
Algorithm – A complex mathematical formula used by a search engine to rank the web pages that it finds by crawling the web.
ALT Tags – Used to display a short text description of an image when you hover your mouse over it. The ALT description is also displayed in place of the image if the user is browsing with image display turned off.
Anchor Text – Anchor text is the text in between the HTML anchor
and tags. This type of link is also referred to as a text link.
Image ALT tags are useful to your page's visitors. Equally as important, they can help with your search engine rankings by increasing the keyword density (if you use your keywords in your ALT tags).
Example:
<img src="blue-widget.jpg" width="156" height="175"
ALT="Photo of blue widget">
Apache Web Server – The web server software that is most used on the internet today.
Accessibility – Web accessibility means access to the Web by everyone, regardless of disability whether it be physical, visual, hearing, and cognitive or neurological disabilities. An accessible Web site allows all users to access it, regardless of their browser, resolution, settings, or eyesight. Not only does accessible mean allowing the Web to be used by people with disabilities, but also allowing Web pages to be understood by people using browsers other than the usual ones - including voice browsers that read Web pages aloud to people with sight impairments, Braille browsers that translate text into Braille, hand-held browsers with very little monitor space, teletext displays, and other unusual output devices.
