In the situation that you have an old website registered under wordpress (for example aaa.wordpress.com). It became quite successful and you decided to purchase "aaa.com".
On aaa.com, you continued talking about the same topic same from "aaa.wordpress.com", and we put links from "aaa.wordpress.com" to "aaa.com". but because "aaa.wordpress.com" was so successful before, that your keyword ranking for "aaa.com" is always behind.
How can we increase the keyword ranking for "aaa.com"?
