Submit URLs for Indexing from Google Search Page
Google just made it a whole lot easier to submit URLs to its search index. In the past, Web developers had to use the Google Search Console or the submit URL form to request that Google begin indexing their sites. Now, however, they can just search for "submit URL to Google" from the main Google search page. That brings up a form that allows you to submit the site right from the page.
The page does use reCAPTCHA technology to make it difficult for bots to submit URLs to the service.
