Google now allows you to submit newly created URLs on your website to their index directly from the Google search results page.
All you need to do is search for "Submit URL to Google", and Google will display a box at the top of the search results that enables you to submit a URL to Google’s index.
This new feature is similar to the one available on the Google Search Console https://www.google.com/webmasters/tools/submit-url.
Recently, I have written about migrating your website to a new domain, so if you're a newbie, you can use this tool to have your new domain or set of pages indexed fast.
You will have to keep in mind though that submitting a URL to Google - whether with this toolor Search Console - does not mean that I will actually be included or it will be shown on their ranking Of course, submitting a URL to Google for inclusion in their search index does not mean (a) it will be included in the index, and (b) it will be shown in their rankings.
