Suppose I have a new website about cars and I had created a page about something completely not-related - like cupcakes. However, I found that it was very easy to get high quality sites to link to the cupcakes page where as it was very difficult to get people to link to the homepage about cars.
If my goal is to increase the SEO for the homepage (which again is related to cars), is there a point where additional high quality links to my cupcakes page is not useful for it anymore? What if I created another page - about frosted cupcakes - which was also easy to get high quality links to?
