Is there necessary to submit the sitemap into Goggle, Yahoo and Bing? All these while, I just submitted to Google. Please help if you know what is the reason behind. Thanks
I believe that if you submit your sitemap your website will be crawled faster, if not you'll have to wait for them to find you and discover all your pages. It doesn't take a lot of time to submit, you can do it in a few minutes. There are no reasons why you shouldn't submit your sitemap to top 5 search engines
it helps google find your pages and it's really only for indexing purposes. It should be one of the first things that you do after creating a site.
Sitemap help your site's every post to crawl within a short period of time by search engine. Submit your sitemap at all of the major search engine & see how fast index all of your post.
Submitting your sitemap is not necessary if it's located in your robots.txt by adding a line that looks something like: Doing this will allow it to be discovered by most spiders. (I know it works with Google.) Submitting your sitemap only changes how soon spiders will use it to crawl your website.
