Complete diagnosis
What is an SEO audit and why does it matter?
An SEO audit is not a generic checklist. It is a forensic analysis of your organic presence that cross-references business data, technical signals, content quality and authority profile to pinpoint with surgical precision what is limiting your visibility on Google.
We cross-reference data from Google Analytics 4 with Search Console, Sistrix and Screaming Frog to detect not only the obvious issues, but the invisible opportunities: keywords where you are about to break into the top 3, cannibalizations diluting your strength, or toxic backlinks eroding your authority without you even knowing.
Without this diagnosis, any SEO investment is a gamble. With it, every action has an estimated impact, a clear priority and a measurable outcome.
Key metrics we evaluate
- Visibility index (Sistrix) vs competition
- Revenue and traffic by organic channel
- Brand vs non-brand traffic ratio
- New vs returning users and engagement
- Indexed vs indexable URLs vs in sitemap
- Crawl depth and crawl budget
- Core Web Vitals and mobile performance
- Internal authority distribution (link juice)
- Keyword gap vs direct competitors
- Backlink profile: quality, toxicity and relevance

Deep dive
Technical analysis
The technical layer is the foundation on which everything else is built. If Google cannot crawl, interpret and index your website correctly, all other SEO efforts are useless.
We use Screaming Frog to crawl every URL as Googlebot would. We cross-reference that data with Search Console crawl statistics and the actual indexation status to detect the discrepancies that are killing your visibility.
Indexation and indexability
We compare the site: command with the sitemap and Screaming Frog to detect discrepancies between what Google has indexed, what you want indexed and what is actually indexable.
Crawlability
We analyze crawl statistics in Search Console: how many pages Google crawls per day, what responses it gets and where it wastes time on irrelevant URLs.
URL structure
We evaluate syntax, depth, chained redirects, unnecessary parameters and structural coherence with the site architecture.
Sitemap and robots.txt
We verify that the sitemap does not contain URLs with noindex, redirects or 404 errors. We audit the robots.txt to ensure it does not block critical resources.
Core Web Vitals
We measure LCP, INP and CLS with field data (CrUX) and lab data (PageSpeed Insights). We identify the specific resources degrading each metric.
Structured data
We audit the existing Schema.org markup, detect validation errors and identify Rich Snippet opportunities that increase organic CTR.
Mobile usability
We review the mobile device experience: touch elements, viewport, text size, intrusive interstitials and issues reported in Search Console.
Security and protocols
We verify correct HTTPS, mixed content, HSTS, HTTP-to-HTTPS redirects and certificates. Any security failure directly impacts Google's trust.
Content
Content analysis
Content is what Google evaluates to decide if you deserve to be on page one. We analyze every layer: from information architecture to perceived quality at the EEAT level.
Information architecture
We evaluate the menu structure, category hierarchy and click depth. A user (and Googlebot) should reach any important page in 3 clicks or fewer. We detect broken silos, confusing navigation and restructuring opportunities.
Cannibalizations
We use a proprietary methodology with Google Sheets that cross-references Search Console data with Semrush positions to identify when two or more URLs compete for the same keyword. Cannibalization is one of the most frequent and most ignored problems: it dilutes your ranking power and confuses Google about which page to show.
EEAT and AI content
We evaluate the Experience, Expertise, Authoritativeness and Trust signals that Google looks for. We detect AI-generated content that may be affecting perceived quality, pages without identifiable authorship, and the absence of first-hand experience signals that Google increasingly values.
Internal linking and link juice
We map internal authority distribution: which pages receive the most internal links, which are orphaned and how link juice flows through your architecture. Poor internal linking leaves your most important pages without the strength needed to compete.
Thin content and duplicates
We identify pages with insufficient content, excessive internal similarity (near-duplicates) and duplicate content that Google may be consolidating into URLs you do not want. Every page must provide unique value or it should not exist.
Images and multimedia
We audit alt text, formats (WebP/AVIF), dimensions, lazy loading and optimization for Google Images. Images represent an organic traffic source that most websites completely ignore.
Off-page
Authority analysis
Domain authority determines your ability to compete for high-difficulty keywords. We analyze your backlink profile with the same rigor we apply to every technical dimension.
We cross-reference data from Ahrefs and Semrush for a complete picture: who links to you, from what type of page, with what anchor text, and whether those links add or subtract. We also look at what your competition is doing and where the opportunities are that you are not leveraging.
Domain authority (DA)
Direct comparison with your top 5 competitors. The absolute number does not matter: your relative position does.
Referring domains
Quantity, quality and diversity of domains pointing to your site. One link from a national newspaper is not worth the same as 100 from directories.
Dofollow/nofollow distribution
A natural profile has both types. An imbalanced ratio can signal manipulation or missed opportunities.
Anchor text
We analyze anchor text distribution to detect over-optimization (penalizable) or under-optimization (wasted potential).
Toxic links
We identify low-quality backlinks, spam or link farms that may require a disavow file in Search Console.
Link gap
Who links to your competition but not to you. Each link is a documented outreach opportunity in the deliverable.
