Three elements of SEO.

[Ashique Raheem]

Your answers are partly correct. SEO is not really easy as you think and in the same time not so hard as well. Well it depends on targeted keyword. Sometimes a keyword with no competition could be ranked with On page optimization alone it requires you to have a good On Page structure. If you targeting a very competitive keyword it requires both On Page and Off page optimization..

I think it is not only about content or keyword or link...It is mix of all as for seo everything is related to each other..only one technique can not give success in seo...

Yes, right but you only be success when you do your competitor analysis what they doing what type of links they are getting etc.

Yeah I agree but of course even though you already done the 3 elements that you said, you still need to do all the aspect of SEO process or any strategy that you know its effective. Just be sure your following the right process and not doing some ethical ways.

Keywords, Content, Links all three are important.
But i think to become good seo analysis is also important.
