Search engine submission for an existing website may be viewed as redundant,
though there are still a variety of new engines and directories
surfacing each day, ensuring that your site is found on all reputable
engines and directories is highly recommended (with our without
NOFOLLOW).
If on the other hand you have recently purchased a domain and have developed the
site, I recommend you do complete a variety of submissions to both search engines and directories. Submitting these by hand, though just as effective, can be time consuming, which is why a submission program or service is practical.
Submission programs or services not only speed the process up, but also help
you manage your submissions and what engines/directories are pending, thus avoiding submission spam (repeated submissions to one site).
So, in short – search engine submissions are not dead, they are alive and well and should be completed on a regular basis, helping promote your website.
Taking all this into consideration let’s not forget that a submission program is just one element of SEO, there are many other factors i.e. content, internal and external links, social bookmarking, meta data, website architecture, content formatting, image optimization etc that make up a full search engine optimization campaign.
