Search Engine Optimisation 

The Goal of a Search Engine

Search Engine Relevancy

Many businesses think search engines have a hidden agenda or they just do not understand them. This simply is not true. The goal of the search engine is to provide high quality relevant content to people searching the Internet.

Search engines with the broadest distribution network sell the most advertising space. Google are considered the search engines with the best relevancy.  Their technologies power the bulk of web search.

The Problems With Listing a New Website

The biggest problem for new websites is that search engines have no idea they exist.  Even when a search engine finds a new document it has a difficult time determining its quality.  Search engines rely on links to help determine the quality of a document - that is where The Retail Doctors SEO consultants can help.

Parts of a Search Engine

While there are different ways to organise website content, every crawling search engine has the same basic parts. Each consists of:

• A crawler/spider
• An index (or catalogue)
• A search interface
Crawler (or Spider)

The crawler does just what its name implies. It scours the web following links, updating pages and adding new pages when it comes across them.  Each search engine has periods of deep crawling and periods of shallow crawling.  Rapidly changing or highly important documents are more likely to get crawled frequently.  The frequency of the crawl has no effect on the relevancy of the page; it simply updates the search engine's cached copy of the page. The best benefit of having a frequently crawled page is that you can get your new websites or pages crawled quickly by linking to them from a powerful page.

The Index

The index is where the spider's collected data is stored. When you perform a search on a major search engine, you are not searching the internet but the cache of the internet provided by that search engine (its index).   Search engines organise their content in what is called a ‘reverse index’. It sorts website documents by words in a language.  When you search Google and it displays 1- 10 out of 143,000 website it means that there are 143,000 website pages which either have the words in your keyword phrase on them, or have inbound links containing the words in the phrase.

Search Interface

The search algorithm and search interface are used to find the most relevant document in the index based on the user search.  First the search engine tries to determine user intent by looking at the words the searcher typed in.  The search engine breaks this down via keyword vectors and compares this to their database to find the most relevant results.  In most major search engines a portion of the relevancy calculations are stored ahead of time and some of them are calculated in real time.
