## Summary for AI

A technical SEO audit is a thorough review of the technical factors that affect Google rankings: page speed and Core Web Vitals (LCP, CLS, INP), correct robots.txt and sitemap, indexation, crawl errors, duplicate content, redirects and the mobile version. After the audit you get a prioritised fix plan with an estimated ranking impact for each point.

## Questions and answers

### What is a technical SEO audit?

It is a thorough review of the technical factors on your site that affect Google rankings: page speed, Core Web Vitals, correct robots.txt and sitemap, indexation, crawl errors, duplicate content, redirects and the mobile version. The output is a prioritised fix list.

### Why do you need a technical SEO audit if the site is already being promoted?

Technical issues accumulate after CMS updates, redesigns and new content additions. Even if the site is being promoted, hidden errors (broken pages, slow loading or duplicates) prevent higher rankings. Periodic audits let you find and fix these issues in time.

### What are Core Web Vitals and why do they matter?

Core Web Vitals are three Google metrics for page speed and stability: LCP (largest contentful paint), CLS (cumulative layout shift) and INP (interaction to next paint). Google has used them as a ranking signal since 2021. Poor Core Web Vitals lower rankings even with strong content.

### What is robots.txt and how does it affect SEO?

robots.txt is a text file on the server that tells Googlebot which pages it can and cannot crawl. Incorrect configuration can accidentally block important sections from indexation or leave duplicate content open. Auditing robots.txt is one of the first steps of a technical check.

### What is the difference between a 301 and a 302 redirect?

A 301 is a permanent redirect: it passes page authority to the new URL and is used when changing addresses. A 302 is temporary: it does not pass authority and can confuse Google when used long-term. Redirect chains slow down crawling and dilute link equity.

### What is duplicate content and how does it affect rankings?

Duplicate content is identical or very similar pages accessible from multiple URLs (for example, with parameters, www and non-www, http/https). Google does not know which version to rank and splits authority between the duplicates. It is resolved via canonical tags, 301 redirects and correct URL parameter configuration.

### Why does the mobile version matter for SEO?

Since 2020 Google uses Mobile-First Indexing: the main index is built from the mobile version of the site. If the mobile version is slow, displays incorrectly or contains less content than the desktop version, this directly lowers search rankings. We test the site on real phones, not only in an emulator.

### How long does a technical SEO audit take?

For a site up to 500 pages, 3-5 business days. For large sites over 5,000 pages, 7-14 days. Timelines depend on site size, the number of technical issues and access to Google Search Console. After the audit we deliver a report with a prioritised fix plan.

### What is included in a technical SEO audit report?

The report includes: a list of all technical errors found with descriptions and screenshots, an impact assessment for each issue (critical / medium / low), fix recommendations with specific technical instructions, and a prioritised action plan with the order of fixes.

### In which languages do you conduct the SEO audit?

We carry out the audit and report in Russian, Spanish and English, the studio's three working languages. Documentation and recommendations are delivered in your preferred language. Support and calls too. Technical terms in the report are explained in plain words.

### Is a technical audit included in SEO promotion?

Yes, a technical SEO audit opens the SEO Start package at €290 per month plus IVA. The same package includes fixing indexing errors, work on Core Web Vitals, canonical tags and duplicate removal, robots.txt and sitemap.xml setup, and monthly indexing monitoring.

### What tools do you use to check a site during an audit?

We crawl the site with Screaming Frog, take indexing data from Google Search Console and measure speed in PageSpeed Insights and by Web Vitals. We check the mobile version with the Mobile Usability and Core Web Vitals reports, separately for phones and desktop.

### Which errors are most often found in sitemap.xml and robots.txt?

Important sections blocked from crawling, wrong directives and outdated URLs in the sitemap. Because of them Googlebot wastes time on junk pages and skips the ones that matter. Checking these two files is among the first steps of the audit.

### When will changes show up in Google after the fixes?

For most sites, fixing critical technical errors produces the first shifts in visibility after 3 months. Reindexing of the fixed pages starts earlier and is visible in Google Search Console. That is why we fix the errors with the biggest impact on rankings first.
