Submitting URL’s directly to search engines allow search engine bots to find your web pages faster, thus allowing your site to show up quicker on their search results. Otherwise, it may take awhile before major search engines find your website. Some search engines take months to release their spiders to find new pages. All this time, you could be missing out on massive amounts of traffic without even realizing it.
How often should you submit your website to search engines? You only need to submit your page once. Resubmitting your website will not allow your website to be crawled more frequently or improve your ranking. Google, being the number one search engine, should be your first priority. Ensure that your website is indexed and submit your URL today!
