2. Off-page optimization: This involves building backlinks to the website in order to improve its visibility and ranking. This can involve creating content, such as blog posts, press releases, and infographics, that link back to the website. It can also involve building relationships with other websites and influencers who can link to the website.

3. Technical SEO: This involves optimizing the website from a technical perspective to ensure that search engine crawlers can access and index the website. This includes ensuring that the website is mobile-friendly, that URLs are optimized, and that the website is free from technical issues that could prevent it from being visible in search engine results.
