The simple answer is no – search engine submission isn’t necessary. The majority of search engines nowadays (most notably Google) crawl and index pages by following links. Using that logic, a single inbound link from any already-indexed page will identify your page to the engine.
For this reason, inbound linking is very important. In fact, acquiring back-links may be the most important of SEO. In theory, though, a website owner shouldn’t have to ’scout’ or ‘hunt’ for links. Further, this is the basis for the Google PageRank algorithm.
With all due respect, submitting your site to the search engines can’t hurt. Most importantly, don’t try Search Engine Submission of your website more than once. It doesn’t help or get your site rank any quicker or more often.
It should be noted that submitting your site to Google, Yahoo, MSN, and many others doesn’t cost a fee.
Tip – Choose a targeted market
The biggest mistake most people make when starting a business is that they choose a product and then try to find people who want to buy it. Don’t even consider starting a business until you know exactly where you are going to get your leads from. Think of targeted customers first.
Then, you can come up with a product for those individuals. Would you rather have 1,000 hits a day at your site of a general audience OR 10 hits a day of people who are desperate and willing to pay any price to buy your products? If you are smart, you will choose the people who are ready to buy!
