What an enterprise SEO audit should include
What an enterprise SEO audit should include: eight areas to check, how to rank the fixes, and a worked example with 99% error-free URLs.
An enterprise SEO audit should cover crawling and indexing, content and domain consolidation, redirects, site structure, page speed, on-page signals, links and measurement. It should end with a short list of fixes ranked by business impact, not a long list of errors.
The difference from a standard audit is scale and decision-making. A large organisation often has thousands of URLs, several domains and many teams who publish content. This article sets out what to include, how to rank the findings, and how one audit helped a US B2B manufacturer reach 99% error-free URLs.
How an enterprise SEO audit differs from a standard audit
A standard audit checks a site against a list of known issues. An enterprise audit has to do more, because the site is larger and more people depend on it.
Three things set it apart.
First, the volume of URLs makes crawling and indexing a real constraint. Second, content is often spread across several domains, brands or regional sites. Third, every fix needs an owner, a budget and a place in a development schedule.
Google’s guidance on crawl budget is aimed at large sites. It names sites with more than one million unique pages that change weekly, and sites with more than 10,000 pages that change daily. Many enterprise sites fall into one of those groups, or have many URLs marked “Discovered, currently not indexed” in Search Console.
For the AI side of an audit, use our tool to check how visible your site is to AI. It shows whether AI crawlers can read your site and how often AI answers cite it.

The chart shows how many S&P 500 websites block each AI crawler from their whole site in their robots.txt file. Few do: ChatGPT’s training crawler is blocked most often, by 11 of 400 sites. An audit should still check your own robots.txt file, because a single line can stop an AI tool from reading every page on your site.
What an enterprise SEO audit should include
We cover eight areas in every enterprise SEO audit. The table gives a summary, and each area is explained below.
| Area | What to check | Main sources |
|---|---|---|
| 1. Crawling and indexing | Blocked pages, indexing status, duplicate URLs, sitemaps | Google Search Console, a site crawler |
| 2. Content inventory | Value of each URL by clicks, depth and relevance | Google Search Console, Google Analytics |
| 3. Redirects and migrations | Redirect chains, broken redirects, mapping of old URLs | Site crawler, server logs |
| 4. Site structure | Navigation, menus, internal links, page depth | Site crawler |
| 5. Page experience | Load times, mobile usability, Core Web Vitals | Search Console, page speed tools |
| 6. On-page signals | Titles, meta descriptions, headings, structured data | Site crawler, Search Console |
| 7. Links | Broken links, irrelevant outbound links, links between your own brands | Site crawler, Ahrefs |
| 8. Access and measurement | AI crawler access, analytics and tracking setup | robots.txt, Google Analytics |
1. Crawling and indexing
Check which pages search engines can reach, which they index, and which they skip. Compare the pages you want indexed with what Search Console reports. Large gaps usually point to duplicate content, weak internal links or pages blocked by mistake.
Google’s crawl budget guidance recommends removing duplicate content and returning a 404 or 410 status for pages that are gone for good. It also recommends keeping sitemaps current and avoiding long redirect chains.
2. Content inventory and consolidation
List every URL and judge its value. We look at clicks, content depth and relevance to the business. Each page is then marked to keep, improve, merge or remove.
This step matters most when content is spread across several domains. Pages that compete with each other split authority and confuse search engines about which page should rank.
3. Redirects and migrations
Check every redirect for chains, loops and broken targets. If a migration is planned, map each old URL to its new address before launch.
Google’s guidance on site moves recommends permanent server-side redirects, such as 301s. It says to keep redirects for as long as possible, generally at least a year, and to expect temporary changes in rankings during a move.
4. Site structure and internal links
Review how pages connect. Important commercial pages should be reachable within a few clicks from the homepage, and linked from related content.
Header and footer menus are often overlooked. On enterprise sites they carry links on every page, so small changes can affect how authority is shared across the whole site.
5. Page experience
Measure load times and mobile usability on the templates that matter most, such as product, category and contact pages. Google’s Core Web Vitals set clear targets.
| Core Web Vitals metric | What it measures | Google’s target |
|---|---|---|
| Largest Contentful Paint | Loading performance | Within 2.5 seconds |
| Interaction to Next Paint | Responsiveness | Less than 200 milliseconds |
| Cumulative Layout Shift | Visual stability | Less than 0.1 |
Audit by template, not page by page. One fix to a template can improve thousands of URLs at once.
6. On-page signals and structured data
Check titles, meta descriptions and headings for gaps, duplicates and pages that target the same terms. Then check structured data. Google describes structured data as a standard format that gives explicit clues about the meaning of a page.
Structured data does not promise rich results in search. It does help search engines understand products, organisations and articles, which supports accurate listings.
7. Links
Find and fix broken internal and external links. Review outbound links too: links to irrelevant or low-quality sites add no value and can weaken trust.
Many enterprise groups own several brand websites. Links between those sites, where relevant, can send authority to the main domain. The audit should map them.
8. Access and measurement
Check that robots.txt and security settings allow the crawlers you want, including AI crawlers. OpenAI’s publishers and developers FAQ says sites that block OAI-SearchBot are left out of summaries and snippets in ChatGPT search.
Finally, confirm that Google Analytics, Google Search Console and your rank tracking are set up correctly. Without reliable data, nobody can measure whether the fixes worked.

Worked example: 71 URLs, three domains, one core site
The client was a US B2B heating and insulation manufacturer, in its market since 2000. When the work began in October 2024, its content was spread across three domains. Ahrefs showed a domain rating of 3 and 5 organic visits a month on the main domain.
The audit and the fixes that followed are summarised below.
| Audit step | What we did |
|---|---|
| Content inventory | Analysed 71 URLs across three domains by clicks, content depth and relevance |
| Consolidation | Relaunched the best content on one core domain; removed outdated URLs |
| Redirects | Added 301 redirects from old URLs to their new addresses |
| Site quality | Fixed broken links, slow pages and indexing issues; improved structure, mobile usability and load times |
| Navigation | Improved header and footer menus |
| On-page signals | Added structured data; improved meta titles and descriptions; improved internal links |
| Links | Removed irrelevant outbound links; used the company’s other brand websites to link to the main site |
| Measurement | Set up tracking in Google Analytics, Ahrefs and Google Search Console |
After the work, 99% of the site’s URLs were error-free. The two secondary domains stayed live and now generate leads through pay per click advertising.
The audit was one part of a wider campaign that also included link building.
By September 2026, Ahrefs showed a domain rating of 61 and 2,762 organic visits a month. Client reporting showed more than 50 qualifying leads a month from organic search. You can read the full story on our case study page.
How to rank the findings
An enterprise audit can produce hundreds of issues. A board or development team needs a short, ranked list.
We score each finding on business impact and effort. Impact asks whether the issue affects pages that bring in leads or revenue. Effort asks how much development time the fix needs.
| Priority | Business impact | Effort | Example |
|---|---|---|---|
| Fix now | High | Low | Broken redirects on product pages |
| Plan next | High | High | Template changes to improve load times |
| Batch together | Low | Low | Missing meta descriptions on old blog posts |
| Review later | Low | High | Rebuilding low-traffic archive sections |
Give each finding an owner and a date. An audit that is not tied to a development schedule is rarely acted on.
Who should be involved
An enterprise audit touches many teams, so agree the people involved before it starts. Findings that reach the wrong team, or no team, are rarely fixed.
| Team | Role in the audit |
|---|---|
| Marketing | Sets business priorities and owns the content decisions |
| Development | Confirms effort, schedules fixes and owns templates and redirects |
| Product or brand teams | Approve changes to product pages and to secondary brand sites |
| Analytics | Confirms tracking is accurate before and after changes |
| Legal or compliance | Reviews changes to regulated content, where relevant |
Name one person as the overall owner. That person keeps the ranked list current, reports progress monthly and decides when a finding is closed.
Share findings in plain language. A development team needs the affected URLs, the expected behaviour and how to test the fix. A board needs the business impact and the date.
How often to run an enterprise SEO audit
Run a full audit once a year, and before and after any major change. Migrations, redesigns, new content management systems and mergers all carry risk. A pre-change audit sets the baseline, and a post-change audit confirms nothing was lost.
Between full audits, monitor the most important signals monthly. These include indexing status in Search Console, crawl errors, Core Web Vitals and broken links on commercial pages.
Our enterprise SEO service includes a technical audit at the start of every engagement, followed by monthly monitoring.

Frequently asked questions
How long does an enterprise SEO audit take?
It depends on the number of URLs, domains and templates. A focused audit of one large site can take several weeks, while a multi-domain audit with a migration plan takes longer.
What is the difference between an SEO audit and a technical SEO audit?
A technical audit covers crawling, indexing, speed and code. A full enterprise SEO audit also covers content value, site structure, links and measurement, and ranks fixes by business impact.
Should we merge several domains into one?
Often, but not always. In our worked example, merging content from three domains into one core site helped focus authority. Analyse each URL’s value before deciding, and plan redirects carefully.
Do AI crawlers need to be part of an SEO audit?
Yes. OpenAI says sites that block OAI-SearchBot are left out of summaries and snippets in ChatGPT search, so check AI crawler access during the audit.
What tools are used for an enterprise SEO audit?
We use Google Search Console, Google Analytics, Ahrefs and a site crawler. Server logs help on very large sites, because they show what search engines actually crawl.
