SEO stands for search engine optimization. It is the process of getting traffic from the free, organic, editorial or natural search results on search engines. SEO basically is is a measurable, repeatable process that is used to send signals to search engines that your pages are worth showing in Google’s index.
How it works?
Without search engines content would all be hand picked just like newspapers and magazines.
There are three basic stages for a search engine:
Search engine uses complex mathematical alogrithm to guess which website a user seeks. In the above diagram each of the bubble represent a website. Each Website is linked to another website with the arrows shown in the diagram. Website getting more inbound links are pre-asumed to be more important and what the user is searching for. The way your web pages are linked to each other also affects your site’s search engine visibility. If search engine spiders can find your pages quickly and easily, your site has a much better chance of appearing at the top of search results.
Crawling: where content is discovered, It is the acquisition of data about a website. This involves scanning the site and getting a complete list of everything on there the page title, images, keywords it contains, and any other pages it links to at a bare minimum.
Indexing: Where it is analysed and stored in huge databases, Indexing is the process of taking all of that data you have from a crawl, and placing it in a big database. Imagine trying to a make a list of all the books you own, their author and the number of pages. Going through each book is the crawl and writing the list is the index.
Retrieval: where a user query fetches a list of relevant. The last step is what you see – you type in a search query, and the search engine attempts to display the most relevant documents it finds that match your query. This is the most complicated step, but also the most relevant to you or I, as web developers and users.
Why is it important?
It is is a never ending process and SEO is important for the smooth running of a big web site. Their direct benefit is increase in search engine traffic and their indirect benefit is having a common framework to use before publishing content on the site. SEO can put once company ahead of the competition. If two web sites are selling the same thing, the search engine optimized web site is more likely to have more customers and make more sales.
