I have a very odd problem. I have done SEO on my website. I have improved my onsite SEO grade to over 85% and it is considered very good. I have submitted my website to several search engines. My site is not penalized from what I know. The problem is when someone types in my target keyword in google, my website does not show on any page at all. What could be the reason for this? This has been going on for two months now.
