If no, then don't worry, I explained you that you just simply paste your website URL and submit it & next day you will see that Google crawled that link when you check your website backlinks. This is not only simple task, but highly beneficial to boost up your website in the Search Engine. All sites which I have mentioned high PA, DA sites, you can also check it out that. I also have Search Engine Submission Sites List. If you think these sites are beneficial, you can share your views with us & if you have other sites, please mention in the comment box.
