SEO Glossary [P-R]
What is page popularity?
Page popularity is a measure of the number and quality of links to a particular page (inbound links). Many search engines are using this number as part of the positioning process. The number and quality of inbound links is becoming as important as the optimisation of page content.
What is a page view?
A page view is common metric for measuring web site traffic, usually representing the viewing of all of the elements that comprise a web page (graphics, text, etc.). Many server hits may be made to access a single page, causing many separate log file entries. Analysis software can determine that these server hits were generated when a visitor viewed a single page, and group them together to provide this more useful method of counting visitors. A single user session may result in multiple page views and numerous impressions. Reload of the same page is another page view.
What is pay per click?
Pay per click (PPC) is a type of search marketing where advertisers pay a set amount every time their ad is clicked by a prospect (otherwise known as a click thru). Some search engines, such as Overture, specialize in this type of advertising medium, although pay per click is not limited solely to pay-per-click engines.
What is positioning?
Search engines and directories order web sites so that the most relevant web sites appear first in search engine results for a particular query. This process is called search engine positioning. This term is also used to describe various techniques used by search engine (web site) optimizers to help the web site rank higher in search engines.
What is a query?
This term generally refers to databases. A query is a formally phrased question requesting information from a database or search engine. A query can be used to retrieve specific information (by keyword, full text, or other means) from a search engine database.
What is query-by-example?
A search where a user instructs an engine to find more documents that are similar to a particular document. Also called "find similar."
What is re-submission?
Repeating the search engine registration process one or more times for the same page or site. Some search engines penalize you if you submit the same page more than one once in a 24 hour period. Occasional re-submission of changed pages is not normally a problem.
What is a robot?
In the context of search engine ranking, it implies the same thing as spider. A robot is a server-based program which follows hypertext links and accesses web pages but is not directly under human control. Examples are the search engine spiders and various intelligent web searching programs. In a different context, it is also used to indicate a software which visits web sites and collects email addresses to be used for sending unsolicited bulk email. A database of web robots is maintained by Webcrawler.
What is the use of a robots.txt file?
A text file present in the root directory of a site which is used to control which pages are indexed by a robot. Only robots which comply with the Robots Exclusion Standard will read and obey the commands in this file. Robots will read this file on each visit, so that pages or areas of sites can be made public or private at any time by changing the content of robots.txt before re-submitting to the search engines.
