Unless your website gets thousands of visitors a day and is very popular, your new blog post or page takes time (sometimes a few hours to a few days) to get indexed in the Google search engine.
Here, I will show you a method to get your page indexed almost immediately. You can do it with the ‘Fetch as Google’ option in Google Webmaster Tools.
It is recommended that you get your page indexed as soon as you publish it. This is important because someone else could copy your content, publish it on their website and get them indexed first.
The search engines could consider that page as the original or authoritative one and rank it higher than your page. This is only a theory, but many SEO experts agree that search engines do give weight to the page that is indexed first.
