Is it Worth Making The Search Engine Submission?
The simple answer is yes – search engine submission is necessary because it will help your web url’s search engine results. Most search engines nowadays (most notably Google) will index and crawl pages by following the links that were posted. A single inbound link from any already-indexed page will be identified as your page to the search engines. That is definitely what you want.
Linking is very important. In fact, it may be the most important aspect of SEO. If the optimized content is relevant, and engaging, then that will trigger social sharing, linking, retweets, etc. This is the basis for the Google PageRank algorithm and how these searches become relevant to rank with Google in the search engines.
