Google now let's you submit URLs in Google's search results

Google search result
Google now lets you submit your URLs to their index directly from their Google search results page as seen in the image above. To get this done, 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 is exactly same as the functionality of the public submit URL form tool but places it directly as a smart interactive answer directly in the search results.

With this tool, you can submit any URL you want to the Google index. Google will then review and see if they want to index the URL and show it in their search results. Of course, submitting a URL to Google for inclusion in their search index does not assure you that it will be included in the index.
