On-page optimization work you or someone add-website based details such as keywords, description, sitemap in your website.

This shared links to index your web page in various search engines via a master web page URL index. Off-page optimization is really useful to compete for another website in the search engine.

Both are the best. But my suggestion compares to others on-page optimization is most important and valuable for search engine optimization. Because major search engines such as Google, Bing, yahoo first look out your web page information via on-page optimization. Then they try to analysis social media shares, back-links etc.
