Let’s just say that people today know what they are searching for – and their specific demands are being met by the engines. They don’t have time to sift through pages and pages of results for a search. Most of the time they are not even willing to go beyond that first page. They want a quick fix and if you are not found at the first click, you are out. Finito.
The web continues to grow at staggering rates. Automated search engines are increasingly unable to turn up useful results to search queries. The small paid editorial staffs at commercial directory sites can't keep up with submissions, and the quality and comprehensiveness of their directories has suffered. Link rot is setting in and they can't keep pace with the growth of the Internet.
To please search engines, you need to be using the keywords you want to be found for. However, you also need to write in a way that pleases human visitors. Learn how to do both, a winning combination that brings you visitors and converts them into customers. More and more site owners are concerned that they might get penalized accidentally or overtly because of duplicate content. If you run mirror sites, will search engines ban you? If you have listings that are similar in nature, is that an issue?
It's important to make a distinction between search engine submission and search engine optimization. These terms, along with others, are sometimes used synonymously to discuss different efforts to promote sites on search engines. "Search engine submission" refers to the act of getting your web site listed with search engines.
