The simple answer is no, a search engine submission isn’t necessary. The majority of search engines, notably Google, crawl and index pages by following links. By that logic, a single inbound link from any previously indexed page will identify your page to the engine.

The answer is clear and simple: No, inbound linking cannot hurt your search ranking. If inbound were to hurt your rank, your competitors would continually link to your site from link farms. Such a scenario is beyond your control. For this reason, Google cannot penalize your site for any inbound linking.

The best way to make your site more search engine friendly is often to simply add more text. The content must add value and be on topic, but the addition will create a new set of keywords and phrases for the search engines to crawl. Think of these terms as new ‘gateways’ for the engines - the injection of text will provide new doorways for traffic.

Whether blogs are good for SEO purposes is actually irrelevant--the content is key. Blogs are simply publishing platforms. Having said that, the ability to produce high quality content on an ongoing basis can be made much easier by leveraging blog software - especially for the for non-technical user.

Inbound linking is very important. In fact, acquiring back-links may be the most important thing in SEO. Nonetheless, a website owner shouldn’t have to “scout” or “hunt” for links. If the presented content is interesting, useful, and/or important, there is a natural tendency among web users to share information.
