What gets reviewed. Indexing and crawl: what search engines actually see, and where they see a generic shell instead of your page. Redirects, including the ones pointing at a homepage instead of the relevant page, which get read as soft 404s. Titles, descriptions, and headings across templates, not just the homepage. Structured data and whether it validates. Sitemap against reality. Core Web Vitals. Internal linking, usually the cheapest unused lever on an e-commerce site. And image alt text, which on CMS-driven sites is empty far more often than anyone expects.
