I need to fix google search console and index pages

I am seeking an experienced SEO specialist to ensure my website is fully indexed by Google. Although my site has been active for over a year, only a limited number of pages are currently indexed, which has hindered my rankings. The ideal candidate will conduct a thorough analysis of my site's structure, optimize on-page elements, and implement effective strategies to enhance crawlability. Additionally, I require guidance on improving my content to align with SEO best practices, ultimately aiming for higher visibility and better search engine performance.
