yes, i am also agree with it that On page and Off page Both are equally important in SEO.

Both are very compulsory and both are different task.

Providing a perfect on-page, building quality backlinks and following the guidelines of Search Engine.

On page is very important for SEO because on page is first time so you can start strong on page after that go to off page and improve the website ranking.

Both are important & effective for a good marketing result purpose. But SEO strategy is a more important thing to get more organic traffic and keyword ranking in quick time.
