Google Drops Submit URL to Google for Indexing
It seems Google officially declared that they have dropped the public submission feature called Submit URL to Google, but webmasters or site owners can still submit their individual page url’s Google Search Console tool.
How to Submit my URL to Google Search Engine?
Log into Google Search Console.
Select your website from the list you have.
On LHS navigation, click on Crawl & goto Fetch as Google option.
Now submit/paste the url that you want Google for indexing in the text box & click FETCH AND RENDER.
Official Announcement from Google Webmasters
We’ve had to drop the public submission feature, but we continue to welcome your submissions using the usual tool in Search Console and through sitemaps directly.
