Without optimization, you may be flogging a very dead horse with search engines rejecting your submissions again and again.
Much emphasis is placed in effective and regular submissions of web sites to search engines.
But, good search engine rankings and listings and the resultant high visitor traffic are not just a matter of hard and sustained work. It is just as important to ensure that you submit a fully optimized web site. Good title, headings, description, meta tags and page content, for example. Imagine, for example, submitting a blank web site page to search engines. Other search engines analyse the text on your page.
