I have 3 money sites. A = normal blog ( writing about everyting. fitness, fashion, health, etc. ) B = money site ( specific subject, keyword targeting ) C = money site ( specific subject, keyword targeting ) B, C backlinking strategy is ok. Because B, C have specific targeting subject and keyword. I have question about A blog's backlinking strategy. I want to improve search engine ranking on Google about A blog. A blog have 20 average search rank in google. ( google webmaster tools search console ) This situation I want to improve A blog's google ranking about every keyword and average rank. What am I supposed to do? Sorry for my poor enlish.... And I'm not live in English-speaking country. So, keyword competition is realatively low. Thank you.
