SEO Technical Basics
The web pages or the whole website is optimized to make it more user-friendly to the end users using Search Engine Optimization or SEO. Many techniques are used in SEO. One should be familiar with HTML, XHTML, CSS and styling sheets to learn and implement SEO. It works by fetching all the web pages linked to the website and creating an index to all the web pages. These web pages are stored in a database and the search engine processes the request when the request is made. The relevant pages are shown and the results are retrieved in the end to the user.
When an article is written already that ranks low in the search engine, i.e. that it does not appear when the customer search for the result, it is better to rewrite the content. The url should not be changed. As the content is improved, when the customer does the search, high chances are there for the page to appear first in the search engine.
Web developers prefer learning SEO due to its marketing technique and simple applications to retain customers to the website. Rather than attracting people physically, it attracts people to the site with its creative and optimization techniques.
