Technical SEO audit checklist for enterprise sites.

Crawl budget audit before anything else

Start by pulling server logs and comparing what search engine crawlers actually request against what the sitemap claims exists. Enterprise sites routinely discover that bots spend most of their budget crawling faceted navigation, internal search results or expired inventory pages instead of the pages that drive revenue.

Fixing this is rarely about generating more content. It is about blocking or noindexing the low-value URL patterns that are eating crawl budget, and confirming with log data over the following weeks that crawl frequency shifts toward pages that matter.

Rendering parity between what users, bots and JavaScript frameworks see

Any enterprise site built on a heavy JavaScript framework needs a direct comparison between the rendered HTML search engines actually index and the DOM a browser shows a user. Gaps here, content that appears visually but is missing from the indexed HTML, quietly suppress rankings for pages that look complete to a human reviewer.

Run this check per template, not per page, since a rendering gap in a shared component affects every page that uses it simultaneously.

Canonical and pagination logic at scale

A single misconfigured canonical rule in a shared template can quietly canonicalize thousands of unique pages to a single parent URL, erasing them from search results without any error message. Audit canonical tags by sampling across every major template type, not just the homepage and a handful of top pages.

Faceted and paginated category pages need explicit rules for which parameter combinations are indexable and which consolidate elsewhere. Leaving this undefined lets the CMS generate its own inconsistent defaults, which is how enterprise sites accumulate index bloat.

Internal linking depth by template

On large sites, product or article pages that sit five or more clicks from the homepage receive a fraction of the crawl frequency and internal authority of pages closer to the surface. Map click depth by template and add contextual internal links from high-traffic pages to flatten the structure for the templates that matter most commercially.

Core Web Vitals segmented by template, not averaged site-wide

A site-wide Core Web Vitals average can look acceptable while one high-traffic template, often the one loaded with third-party scripts for personalization or ads, drags down user experience and rankings for its entire section. Segment performance data by template and fix the worst offender first rather than chasing a single blended number.
