When responding, please send references of past work (websites, etc)
People references are a plus!

I have a website since 2012. I have a facebook, instagram, and google page. I dont need help with social media because we do that inhouse. Basically I need the following:

Installation of Google Analytics for Site Tracking
Google Search Console Setup
Basic Keyword Research
Optimization of Head Tag
Title Tag Optimization
Optimize Page Description for Click Through
Addition of Text Links
Image Optimization
Duplicate Content Scan
Broken Internal Text Link Scan
Quarterly Site Maintenance Check (email/review phone call)
