Audit my website and give me a prioritized fix list

Audit my website [URL] as a first-time visitor who might become a customer, then as a search engine. Click through every main page on desktop and mobile widths. Check: does the homepage say what we do and for whom in five seconds; is the primary call to action obvious and working; are contact details, pricing, hours, and proof (reviews, logos, case studies) easy to find; do forms submit; are there broken links, slow pages, missing meta titles and descriptions, thin pages, or duplicate content. Compare the top search results for [my main keyword] and note what they do that I don't. Give me a fix list ranked by impact and effort, each with the page, what's wrong, what to change, and why it matters. Include the three changes I should make this week and the exact copy you would use for the headline and CTA. Do not submit forms with fake data or change anything on the site.
