How To Check
To check, type site:yourdomain.com in the search box of your browser. You only type your naked domain.com. For example, my website is www.ngbrain.com, all I need to enter is the ngbrain.com (without the prefix www.).
So you now have site:ngbrain.com . Then hit Search.
You’ll see how many pages is being indexed at the moment, depending on the number of pages you have. If your static pages or any unwanted pages is being indexed, you can block it with your robots.txt file. Then check again after some days.
