Initial efforts from the first SEO were good, but the bigger issue here is that google is having a hard time finding our pages. Because React is a SPA SEO becomes a little more tricky, because of how client side rendering works.

The main focus of SEO V2 will be google bot discoverability, which means

• Creating a site map so google can find all our feed pages ex: feeds/mdb-125
• Adding canonical link references in the head so google knows these pages are distinct
• Preventing google from crawling DEV / QA environments
• Improving the HTML structure on Mobile (since thats how google crawls)
• Link the MobilityDatabase from Mobilitydata.org
