i try to got my homepage top 10 for nartuo manga and naruto . but i heard of someone tell me, the two keywords are relevant but conflict. if you put many naruto on homepage, which will reduce relevance of naruto manga. right? another question, if i put more naruto manga on homepage, reduce naruto, is hompage more relevant to naruto manga , less relevant to naruto, right?
You can choose one and try to optimize for it, and possibly create another page for the other one. Or you can try to do both on the same page. It's hard to know beforehand which will work best.
I'm not sure what Naruto or Manga is. Maybe I'm not with the times, who knows but if both those terms are about similar things you should be able to rank that page for both with enough content supporting each. However if those two terms are unrelated then they should each get their own page.
if the two keywords is highly competitive, is it better to create two page for them? do you mean the two kws are conflict ,right? if you guys not know what the two mean, consider these two: red widget and widget.
Definately use them both on your homepage, they will compliment each other and it will be easy to rank for either word or combinations of these words. For instance i rank for "SEO" and "SEO Company" which are alot more competative and havnt used seperate pages for each. Just include both in your page title, description and on your page then get backlinks with these terms as anchor text.
Yes you can rank for both, especially if they are related. I would create a page for each as well and include both terms together (if they are related) as anchor text through out your site and anywhere else.
