SEO for My Simple PHP Website

I need On-Page & brief Off-Page SEO done for my 6-page blog website. It’s made with custom PHP. • Generate keywords • Title & meta tags & meta description • Tighten internal linking - You’ll be working directly in Laravel PHP so u need to be comfortable editing raw code...
