On-page SEO and off-page SEO have different challenges. On-page SEO is easier to control because you handle it directly on your website. You should focus on optimizing keywords, titles, and meta descriptions. You must ensure your site has quality content and fast loading times. Off-page SEO is harder because it depends on external factors. You need to build backlinks from high-authority sites. You must engage with others to improve your online reputation. Both require consistent effort and strategy. You should balance both for the best results. The difficulty depends on your experience and the resources you have available.
