Why WordPress needs its own SEO work
WordPress generates URLs on your behalf. Author archives, date archives, tag pages, attachment pages, paginated comment threads — all indexable by default, all near-empty, all competing with the pages you actually wrote. Layer on a page builder and a caching plugin fighting each other and you get a site that is slow for reasons no generic audit surfaces. None of that exists on a hand-built site, which is why this is scoped separately rather than folded into a general SEO retainer.
