Search Engines

How search engines work

1. A Spider or Robot
A program called a spider, also sometimes called a robot,
regularly ‘crawls’ the worldwide web recording all content and links

2. Storage system or Database
The content recorded by spiders is stored on search engines’ servers

3. A Matching process or ‘Relevancy Algorithm’
When a user Searches with a keyword phrase, the Engine produces a Search Engine Result Page (SERP) which lists the most relevant content pages associated with the keyword

The Search Engine Landscape

Google is by far the most popular Search Engine: In the UK alone, Google represents 78% of the consumer search market - Yahoo 11%, MSN 5% and Ask 3%.

All the major engines also boast a huge reach through their web partnerships and content networks - where the engines serve ads on 3rd party websites, based on the relevance of their content.

The Google content network reaches 65% of the UK online population.

Use of search engines is a worldwide phenomenon. While usage varies from country to country, search marketing principals stay the same.
