What is SEO ?
Search Engine Optimization is the process of getting your website to rank high in Google or other search engine results pages. This chart, from Marketing Sherpa, evaluates how companies think about their goals and objectives for SEO. It also sheds some light on the metrics that gauge success.
Optimizing a site for search engines and creating keyword targeted content produces direct traffic from the engines, which typically expands into content sharing, direct traffic and referring links as more and more people find, use and enjoy the work you've produced. There are thousands of sites on the web that leverage this traffic to serve advertising, directly monetizing the traffic sent from the engines.
To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots. When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed, and will instruct the robot as to which pages are not to be crawled.
