I recently optimized the homepage of a website for a certain easy keyword. The homepage received an A grade on Moz and SEOPressor and was well optimized for the keyword. I also spent money on buying a backlink package on the homepage for that keyword. The rankings then dropped a little after a while. When I searched manually for that keyword I saw that the website is actually showing up for that keyword but a sub-page of the website shows (not the homepage). The sub-page contains the keyword a few more times and even has the keyword in the URL. So what should I do in this scenario? 1) Delete the sub-page so that Google might show more precedence to the homepage? (Since Google usually only likes to show an instance of a website only once in the first 10 pages). Sounds stupid but the pros of doing this is that the homepage is stronger, older, and has more links than this inner page. It is risky though because I'm banking on the homepage to "take over" in the SERPs if I delete the inner page. or 2) Stay with the inner page. Build links to this inner page instead. Optimize it even more than it is. Any advice?
