A set of rules that a search engine uses to rank the listings contained within its index, in response to a particular query. No search engine reveals exactly how its own algorithm works, to protect itself from competitors and those spamming the search engine.
A small program, often written in Java, which usually runs in a web browser, as part of a web page. It is possible that the use of such a program may cause spiders and robots to stop indexing a page.
When pages are removed from a search engine's index specifically because the search engine has deemed them to be spamming or violating search engine guidelines.
Abbreviation for robot (also called a spider). It refers to software programs that scan the web. Bots vary in purpose from indexing web pages for search engines to harvesting e-mail addresses for spammers.
A copy of a web site on held on a computer, or in a search engine's index. On personal computers, cache is used to save a copy of web sites images, text and code to help speed up download upon future visits to the site. On search engines, cache serves as a record of the content of a web page when a search engine last visited and indexed it.
Also called bots or spiders; programs that follows links to visit web sites on behalf of search engines.

Also used when the content is based on a large database of products. Dynamic pages often pose difficulties for search marketing that static pages do not.

A technology invented by Macromedia that brings a far richer user experience to the Web than drab old HTML, allowing animation and other interactive features that spice up visual tours and demonstrations. search engine spiders are unable to index content in the flash programs, and may not index the web page containing heavy flash programming.
An HTML technique allowing web site designers to display two or more pages in the same browser window. Many search engines do not index framed web pages properly - they only index the text present in the NOFRAMES tag. Unless a web page which uses frames contains relevant content in the NOFRAMES tag, it is unlikely to get a high ranking in those search engines.
Googlebot is the Google's spider or crawler or bot; it travels the web finding and indexing pages for the Google search engine. Googlebot leaves it's identity on your web server's log file. Webmasters should study their server log files closely to see the googlebot's visit is successful and is able to crawl the whole site.
Continuously changing results from google while they are upgrading the datacenters from which the results are served. Your ranking in the results appears to "dance", varying minute to minute. "Google dance" is an unofficial term to these continuous changes during the period when Google is performing the update to its index. Though Google may be upgrade their systems and achieve a continuous update of the algorithm, the dance is still ocurring every one ot three months.
The percentage of your site’s pages included by the search index, calculated by dividing the number of pages found in a search index by the total number of pages you have estimated to be on your site. For example, if yahoo reports that you have 20 pages indexed, and your content management system has 40 pages in it, your yahoo inclusion ratio is 50 percent.
Also known as search index refers to the database of web pages maintained by a search engine or directory.
Pages that are included in a search engine's index. An important step in search engine optimisation in insuring your web sites pages are included, indexed, in the search engine databases. Search engines index pages through the spiders or robots.
A programming language that can provide special effects inside a browser that cannot be performed in HTML. Search marketing success depends on certain standards about how and when JavaScript programming is used, because JavaScript, when misused, cat, prevent search spiders from indexing certain pages.

A service offered by some search engines, such as Yahoo!'s premium service, that guarantees a Web site’s pages are stored in the search index in return for a fee.

The process submitting your web site to a search engine in order to be included in the index or directory. The submission does not guarantee listing or ranking. In addition, submission does not help with rank improvement on crawler-based search engines unless search engine optimization efforts have been taken. Submission can be done manually (i.e., you fill out an online form and submit) or automated, where a software program or online service may process the forms behind the scenes.
A means of sending your data to a search engine, instead of having the spider crawl your site. Some niche search services and almost all shopping directories and search engines require the use of trusted feeds to load your data into their search index.
A search engine that focuses on a one topic. A niche web content site with a searchable search engine is a vertical market search engine.
