Hi Friends,
First of all, you should build a sitemap.
When it’s ready, go to Google Search Console and click on "Start Now." You'll be brought to your new dashboard where you can add properties (domains) or view the current properties you have. Click the dropdown in the menu pane for "Search Property" and select your domain. If you don’t have any properties, you should create it.
Once you add the domain, Google will need verification of ownership. When you verify your domain, you'll be brought back to your dashboard with an overview of your website. Using your menu panel, select "Sitemaps" to proceed to the next step.
