Technical SEO health is critical for rank leadership & therefore new visitors.
"Technical SEO can win or lose the game for your business right out of the gate. It can easily be the determination between position 10 on 1st page search results or position 11 on the second page.
As of August 2021 Google has fully rolled out their core algorithm update more heavily valuing Web Vitals, Page Experience, Speed & Mobile... ergo Passing Web Vitals (get a thorough technical seo audit to see) should be Priority #1 in a competitive landscape."
