What is Search Engines

This is the descriptions of technical term of Search Engines that you’ll need to know for having better understanding about SEO.

Search Engines
If you don't know what a search engine is congratulations on finally making it out from under that rock. Search engines are essentially programs that scan an existing index of the web based on a query of search terms, or keywords, that a user enters. However, the word more commonly refers to companies as a whole - Google, for example, controls a search engine, while Googlebot is the crawler that gathers content for its index, but most users and webmasters think of a search engine as the whole package.

Search Engine Marketing
Most often this refers to Pay-Per-Click marketing in which an advertiser bids on chosen keywords and writes several ads to be displayed should their bid achieve placement. These ads are displayed in the "sponsored" section of search engine result pages (SERPS). However, in some circles this term is used to refer to any action taken to gain rankings both paid and organic.

Search Engine Optimization
This one is open to interpretation. It is quite often used to encapsulate a huge amount of different tactics. On-site optimization, off-site optimization (link building, etc) and many other techniques all feasibly fall under the SEO blanket. However, there is an obvious difference between optimizing a page's code to be clean and search friendly and writing link bait that will be popular and get linked to.

Search Engine Results Pages (SERPs)
The pages resulting from a search engine query run by a user. Webmasters review these pages to determine where their pages are ranking for certain search terms.
