Index M
Meta refresh
Attribute in a meta tag in which one URL is replaced with another URL after a specified period of time. A method of redirecting end users from one URL to another.
Meta revisit
Attribute in a meta tag in which web designers instruct the search engine spiders to return to a web page within a specified period of time. Search engines do not honor this attribute.
Meta tag
An HTML tag, placed between the HEAD tags, that gives information about the content of a web page, such as what HTML specifications a web page follows or description of a web page's content. A meta tag, however, does not affect how a web page is displayed on a browser. For online marketing, the most common uses for meta tags are the keyword, description, and robots exclusion attributes.
Mirror domains or mirror sites
Multiple copies of web sites, often on different servers, with the exact same, or similar, content. Used to artificially boost link popularity and search engine visibility.

Index N
Navigation button
A graphic image, generally in a GIF or JPEG format, that links to a single URL
Noframes
An element commonly used on framed pages. Content placed between the NOFRAMES tags display when a browser does not support frames or is configured not to display frames. Because almost all browsers support frames, search engines either ignore or place low weight on the content inside the NOFRAMES tags.
Noscript

Also known as a spider or crawler, but the term "robot" is more and more commonly associated with automated agents.
Robots Exclusion Protocol
A text file that you place on your server that instructs search engine spiders to not spider and record the information in specified areas on your web site. The same function can also be utilized using the meta-robots tag.
ROI
The total value gained after a solution has been deployed. This is usually a figurative term, like total cost of ownership, since the true cost of deployment or migration is hard to quantify. A positive return on investment is desirable, since that means the solution has solved more problems than it creates.

Some Search Engine Optimisation techniques are frowned upon because they involve trying to 'mislead' the search engines into believing your site is more relevant to a search term than it really is.

Static Typed
Static typed programming languages are those in which variables need not be defined before they're used. Static typing does not imply that you have to declare all the variables before you use them; variables maybe be initialized anywhere, but developers have to do so before they use those variables.
Stemming
Stemming is the ability for a search engine to search for variations of a word based on its root. For example, if the word "running" is typed into a search query, search engines that utilize stemming might also display documents that contain the word "run."

Unfortunately, support for XHTML in browsers is poor, with the leading browser, Microsoft Internet Explorer, not supporting the XHTML mime type 'application/xhtml+xml'.
XML
Extensible Markup Language (XML) is an extremely simple dialect of SGML. The goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML.
