In classical SEO times (the late 1990's), search engines had
"submission" forms that were part of the optimization process.
Webmasters & site owners would tag their sites & pages with
keyword information, and "submit" them to the engines. Soon after
submission, a bot would crawl and include those resources in their
index. Simple SEO!
Unfortunately, this process didn't scale very well, the submissions
were often spam, and the practice eventually gave way to purely
crawl-based engines. Since 2001, not only has search engine submission
not been required, but it is actually virtually useless. The engines
all publicly note that they rarely use "submission" URLs , and that the
best practice is to earn links from other sites. This will
expose your content to the engines naturally.
You can still sometimes find submission pages (here's one for
Bing),
but these are remnants of time long past, and are essentially useless
to the practice of modern SEO. If you hear a pitch from an SEO offering
"search engine submission" services, run, don't walk, to a real SEO.
Even if the engines used the submission service to crawl your site,
you'd be unlikely to earn enough "link juice" to be included in their
indices or rank competitively for search queries.
