A technical SEO audit is a structured review of how search engines crawl, render and index a website, with every issue documented and ranked by impact. Busca Orgânica delivers the audit remotely from Brazil, with evidence for each finding and fixes written so your developers can estimate and ship them.
A technical SEO audit answers a basic question that comes before any content or link work: can Google find, render and keep your pages, and does it understand which version of each page counts? On many websites the honest answer is "partly". Pages are left out of the index, duplicates compete with originals, JavaScript hides content from crawlers, and redirects chain through old URLs. Content and links achieve little until those problems are fixed.
What We Check in a technical SEO audit
| Area | What we look at | Main sources |
|---|---|---|
| Crawlability | robots.txt rules, crawl depth, orphan pages, server errors, redirect chains | Full site crawl, Search Console crawl stats |
| Indexing | Excluded pages and the reason for each, canonical tags, noindex, duplicate versions of the domain | Search Console page indexing report, URL Inspection |
| Rendering | Content and links that only appear after JavaScript runs | Rendered HTML compared with source HTML |
| Performance | Core Web Vitals measured on real users: LCP, INP and CLS | Chrome UX Report, PageSpeed Insights |
| Site structure | Internal links, URL patterns, pagination, faceted navigation | Crawl data, analytics |
| Structured data | Valid schema.org markup that matches the visible content | Rich Results Test, Schema Markup Validator |
| International setup | hreflang and targeting when one site serves the US, Ireland or other markets | Crawl, Search Console |
| AI crawler access | Whether robots.txt allows or blocks the crawlers of AI search tools, according to your decision | robots.txt, server logs |
One detail shows how quickly this field changes: INP (Interaction to Next Paint) replaced FID as a Core Web Vital in March 2024, and checklists written before then often still measure the retired metric. We keep our checklist current with Google documentation rather than with tool defaults.
How the Audit Is Delivered
The deliverable is a prioritized list, not a raw export from a crawler. Every finding includes:
- The problem in one sentence of plain English.
- The URLs or templates affected, with a count.
- The evidence: a Search Console report, crawl data or a screenshot.
- The fix, written so a developer can estimate it.
- Severity and effort, so quick wins can be scheduled first.
We present the findings on a video call, walk your team through the critical items and answer questions from developers. Issues that look alarming in tool dashboards but have no real impact are labeled as such, so no one spends a sprint on them. The report is in English and the call happens in your business hours: Brazil is 1 to 2 hours ahead of the US East Coast and 3 to 4 hours behind Ireland, depending on daylight saving time.
How We Rank Each Finding
Severity is decided by what the issue does to search visibility, not by how many warnings a tool shows. We use four levels, and every finding in the report carries one of them.
| Level | Meaning | Example |
|---|---|---|
| Critical | Stops important pages from being crawled, indexed or understood | A noindex tag on all service pages after a release |
| High | Weakens rankings for pages with commercial value | Canonical tags pointing product pages to their category |
| Medium | Wastes crawl resources or splits signals across duplicates | Filter combinations open to crawling on a large catalog |
| Low | Good practice with limited effect on its own | Missing alt text on decorative images |
Effort is rated separately, after a conversation with your developers when possible, because the same fix can be a setting in one CMS and a sprint of work in another.
Our Audit Process
- Access: read access to Search Console and analytics and, when possible, server logs.
- Crawl: a full crawl of the site, with and without JavaScript rendering, compared with the XML sitemaps.
- Index comparison: what Google has indexed against what you want indexed.
- Template review: we test each page template once instead of reporting the same issue on a thousand URLs.
- Prioritization: findings sorted by severity, number of pages affected and effort.
- Presentation and handover: the report, the walkthrough call and follow-up questions from your team.
Findings We See Again and Again
Some problems appear on site after site. Staging environments or old domains left open to indexing. Every page canonicalized to the home page by a theme setting. XML sitemaps listing redirected or deleted URLs. Category filters generating thousands of crawlable combinations. Contact forms that fail on mobile, which is not strictly an SEO problem but costs leads all the same. These patterns, gathered across more than 700 clients served in Brazil since 2021, shape the order in which we check things.
Websites built for both the United States and Ireland add their own layer. A single English site serving both markets may need hreflang for en-us and en-ie when prices, spelling or legal information differ, and no hreflang at all when the pages are identical. Getting that decision wrong can lead Google to show the Irish page to American searchers or to treat the two versions as duplicates. The audit states which setup fits your case and why.
When a Technical Review Is Worth Running
A technical SEO audit pays off most in these situations:
- Before or after a redesign, a CMS change or a domain migration.
- When organic traffic drops and there is no obvious cause.
- When Search Console shows a growing number of pages that are not indexed.
- Before investing in content or links, to confirm the foundation is sound.
- When you change hosting, add a language or open the website to a new country.
What the audit does not do is equally clear. It does not rewrite content, build links or fix the code itself. A technical SEO audit is a diagnosis with a treatment plan, and its value depends on the fixes being implemented.
What Happens After the Audit
Some clients implement the fixes with their own developers and use our SEO consulting services to review tickets and validate deployments. Others hand the full roadmap to us as part of an ongoing SEO agency engagement. Once the technical base is sound, off-page work such as our link building services starts to pay off, and the same structural fixes help AI systems read your pages, which is where our AI SEO agency work continues.
