I would highly recommend manually submitting your web pages to the search engines. It is being said that search engines gives no guarantee of ranking your web page because you have manually submitted. It is a tool that let search engines know that we have new information or update to share.
I would definitely suggest to submit your web pages manually to Google, Bing, Yandex and Baidu as in light of the fact that they have made it clear that it is the thing that they incline toward. Search engines have implemented manual submission as a best practice to shield themselves from great levels of spam.
It is imperative to submit your web pages to all of major search engines because even though the other engines have less traffic than Google, still they have millions of users. When you submit a URL or domain name to the search engines, it can take about 2-4 weeks to get indexed. Sometimes your page will not get indexed after you submit it, if that occurs, wait 4 weeks and then resubmit the page again.
If you are not happy with your web page's ranking results, take a glance at what your competition is doing. Make sure twice that you are following the basic rules of search engine optimization. Accordingly make changes to the page and resubmit it to the search engines. You can submit your web pages twice per month until you are listed in the major search engines' results.
There are two basic techniques still being used today that would permit a webmaster to submit their web page to a search engine. They can either submit only one web page at once or they can submit their entire site at one time with a Sitemap. In short webmaster needs to do is to submit just the Home page of a website. With just Home page, most search engines are able to crawl a website, provided that it is well designed.
How websites are submitted
Most of the website want to be listed in popular search engines because that's how many people start their search for a product. User seeks information on the web with the help of search engine. Websites that show up on the first page are usually called as Top 10.
In order to acquire good placement on search results in various search engines, webmasters must optimize their web pages. This process is called as Search Engine Optimization. Many variables come into play such as placement and destiny of desired keywords, hierarchy structure of web page and the number of web pages that link to a given web page. The Google search engine also uses a concept known as Page Rank.
Page Rank depends on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at considerably more than the sheer volume of votes or links a page receives.
For Example: It also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important." Using these and other factors, Google provides its views on pages' relative importance.
