SEO is the active practice of optimizing a web site by improving internal and external aspects in order to increase the traffic the site receives from search engines.
Search engine optimization is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results for targeted keywords. As a marketing strategy for increasing a site's relevance, SEO considers how search algorithms work and what people search for. Another class of techniques, known as black hat or spamdexing, use methods such as link farms and keyword stuffing that tend to harm search engine user experience. Some search engines have also reached out to the industry, and are frequent sponsors and guests at SEO conferences and seminars.
Many SEOs and other agencies and consultants provide useful services for website owners, from writing copy to giving advice on site architecture and helping to find relevant directories to which a site can be submitted. You should never have to link to an searche engine. Avoid marketers that talk about the power of "free-for-all" links, link popularity schemes, or submitting your site to thousands of search engines. Some marketers may try to sell you the ability to type keywords directly into the browser address bar.
The objective of Search Engine Optimization is to increase web visitor counts by ranking very high in the organic results of searches using the most appropriate keywords describing the content of your site.
Search engine can also target different kinds of search, including image search, local search, and industry-specific vertical search engines. They look for sites that employ these techniques and may remove them from their indexes.
Webmasters and content providers began optimizing sites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Search Engine Marketing (SEM) involves a combination of free website submissions and paid search engine listings, to ensure your website reaches customers using search engines to research purchase decisions. Search engines work for you non-stop 24/7. The answer is entirely dependent upon your web site's visibility amongst the search engines. The goal of web optimization is to create consistent and targeted traffic through search engines and directories to your web site. Search engine optimization is not just to rank in search engines but mainly to achieve a good click through rate from the targeted visitors. This means that your web site should come up in the search results of the search-engines with targeted keywords that are related to your content or theme of your site. If your web pages are dynamically created from the database, it's likely that many search engines have difficulty to crawl and index them. Disadvantage of dynamically created pages are that many search engines like Google for example don't like dynamically created pages because the crawlers might get in an infinite loop on your server if they follow dynamically created web pages with a query string in it.
