Key takeaways
- Audit in order: crawl access and indexing, then on-page templates, then performance, then structured data and AI readiness.
- Template-level issues affect thousands of pages at once, so fix them before one-off page issues.
- Log files and crawl data together show what neither shows alone.
- Titles still count: Google said in 2021 it uses the HTML title element about 87% of the time, though an Ahrefs study of 953,276 pages measured closer to 67%.
- Tie every finding to estimated traffic impact and effort so developers know what to do first.
A technical SEO audit for an enterprise website is a different job from auditing a 50-page small business site. Scale turns small issues into site-wide problems, and fixes compete with every other request on the development backlog. This Emulent checklist covers what to check, in what order, and how to turn findings into a plan.
Can Google reach and index your content?
Confirm access first, because nothing else counts if Googlebot cannot crawl the pages you want to rank.
- Robots.txt: make sure it does not block important sections or the CSS and JavaScript Google needs to render pages.
- XML sitemaps: confirm they load, parse and list only 200-status, indexable, self-canonical URLs.
- Page indexing report in Search Console: review excluded pages, paying close attention to “Crawled – currently not indexed” and “Discovered – currently not indexed.”
- Server logs: extract verified Googlebot requests to see which URLs are crawled, how often and with what status codes.
- Redirect chains: collapse chains to a single hop. Googlebot follows up to 10 hops, but each one slows crawling and adds failure points.
Are your page templates sending the right on-page signals?
Check patterns by template rather than page by page.
| Template element | What to check |
|---|---|
| Titles | find missing, duplicate and overly long titles. Google measures display width in pixels, not characters, and rewrites titles it finds unhelpful. Google said in 2021 that HTML title elements are used around 87% of the time, while an Ahrefs study of 953,276 pages found titles used as written 66.6% of the time. |
| Meta descriptions | flag missing, duplicate and auto-generated ones. They are not a ranking factor but can shape the snippet and clicks. |
| Headings | make sure each page has a clear main heading that matches its topic and a logical H2/H3 structure. Google has said multiple H1s are not a problem in themselves. |
| Canonicals | confirm self-referencing canonicals and no targets that redirect or return errors. |
| Internal links | find orphaned pages and important pages buried deep in the click path. |
One template change can fix titles on 50,000 product pages at once, which is where enterprise audits pay off.
Does your site meet Core Web Vitals thresholds?
Use field data, and check mobile first. Google completed the move to mobile-first indexing in 2024, and INP replaced FID as a Core Web Vital in March 2024.
- Review LCP (2.5 s), INP (200 ms) and CLS (0.1) at the 75th percentile using Chrome UX Report data in Search Console or PageSpeed Insights.
- Measure Time to First Byte from several regions; Google’s guidance treats 800 ms or less as good.
- Inventory third-party scripts and measure what each costs.
- Check image formats, sizing and lazy loading below the fold, but never lazy-load the main hero image.
Performance is cross-functional: developers own the code, but marketing and ad teams add scripts.
Is your structured data accurate and your content machine-readable?
Validate markup for rich results and make entities clear for AI systems.
- Extract JSON-LD across the site and validate each type against Google’s required and recommended properties.
- Confirm coverage by template, such as Product on product pages and Article on articles.
- Check that Organization, Person and content markup connect authors, brand and pages for AI search systems.
- Review content structure: clear headings, answer-first paragraphs and server-rendered HTML that crawlers without JavaScript can read.
Expect change. Google retired HowTo rich results in 2023 and stopped showing FAQ rich results for all sites on May 7, 2026, and its AI features require no special schema.
How do you turn audit findings into an action plan?
Rank findings by traffic impact and effort, then batch them into sprints.
- Score each item: a template fix on 50,000 product pages outranks alt text on one blog post.
- Group fixes by the system they touch. Robots.txt and sitemap changes often ship without development sprints; template changes need them.
- Set a four- to six-week measurement window after each sprint and track indexed pages, crawl stats, rankings and traffic for affected templates.
An audit is only worth what gets implemented, so build the report around a ranked fix list rather than a long document.
How can the Emulent team help?
Emulent runs enterprise technical audits and delivers implementation-ready fix lists as part of enterprise SEO programs. A caveat: an audit is a snapshot, and sites change weekly, so schedule follow-up checks after major releases. Contact the Emulent team to plan your audit.
