seo tecnica
SEO is in the details. Those who they are not seen.
Even the best content and most authoritative backlinks produce partial results on a technically weak site. Authority doesn’t flow where it should, the crawl budget wears out on the wrong pages, slow pages lose positions regardless of what’s in them. Technical problems accumulate in silence and emerge when they have already caused damage that is difficult to quantify.
Bliss intervenes on the site’s technical infrastructure as the foundation of any organic visibility strategy. Diagnostic audit, prioritized interventions, continuous monitoring. Technical SEO isn’t a one-time intervention: it’s the maintenance of the most important asset a company has on the web.
Definition
What is Technical SEO and why it is the foundation
Technical SEO is the branch of Search Engine Optimization that deals with the infrastructure of a website: everything that is neither content nor link building, but which determines whether Google can crawl, index, and understand each page correctly. Without this foundation, the rest of SEO work produces less than it deserves.
We could call it the art of the invisible: as long as everything works, no one notices. When it fails, the positioning collapses in silence. Duplicate URLs automatically generated by the CMS consume crawl budgets without producing value. Incorrectly configured canons disperse authority between different versions of the same page. Unoptimized images lower Largest Contentful Paint below Google’s quality threshold. All problems that accumulate invisibly, and that emerge when they have already produced damage that is difficult to quantify.
Technical SEO steps in before this happens. And when it has already happened, it diagnoses and resolves precisely, not with generic interventions.

the areas of intervention
Technical SEO: The 6 Areas intervention
Technical SEO is divided into six distinct but interconnected areas. One problem in one often affects the others: a poorly managed budget crawl prevents indexing of optimized pages; missing structured data limits rich snippets even on excellent content. Bliss maps all six before deciding where to start.
01.
Crawling and indexing
Google needs to find the right pages. The crawl budget is optimized by excluding URLs without organic value.
- robots.txt and crawl directives
- Structured XML sitemap
- Indexing coverage (GSC)
- 404 Error Handling and Redirects
- Googlebot log file analysis
02.
URL and canonical structure
Each URL has a precise function. Authority is not dispersed among duplicates or non-canonicalized variants.
- Canonical tag configuration
- Parametric URL Management
- Consistent URL architecture
- Redirect chain and loop
- Versions www / non-www / HTTP
03.
Core Web Vitals and performance
LCP, INP, CLS: The three metrics Google uses as a direct ranking signal. Optimized page by page.
- Largest Contentful Paint (LCP)
- Interaction to Next Paint (INP)
- Cumulative Layout Shift (CLS)
- Image optimization and lazy loading
- Deleting render-blocking resources
04.
Structured data (Markup scheme)
JSON-LD schema.org for rich snippets, AI visibility, and semantic understanding by Google.
- Organization, LocalBusiness
- Product, Offer, Aggregate Rating
- Article, FAQPage, HowTo
BreadcrumbList, Event, Person - llms.txt for AI visibility
05.
Ottimizzazione on-page tecnica
H1 tags, meta titles, meta descriptions, ALT attributes: the on-page signals that Google reads to understand each page.
- Audit and normalization H1 tags
- Meta title and description for keyword
- ALT image attributes (SEO + WCAG)
- Internal linking and anchor text
- Security external links (noopener)
06.
Backlink profile and audit link
The external authority of the domain depends on the quality of the link profile. Toxic links should be identified and removed.
- Full backlink mapping
- Toxicity analysis by link
- Disavow via Google Search Console
- Monitoring new links acquired
- Anchor text distribution
Method
Audit, priority, intervention.
Then we start again.
Technical SEO is not addressed with a generic checklist applied to any site. It is approached with a domain-specific diagnosis, followed by a plan of interventions prioritized by expected impact on the ranking. Each site has its own hierarchy of problems. The order of interventions determines how quickly you see results.
Existing backlink profile audit
The mandatory starting point is the complete mapping of the existing backlink profile: active referring domains, anchor text distribution, link toxicity, and thematic coherence of sources. This audit yields two lists: links to disavow (toxic or artificial links risking penalties) and links to replicate (sources that transfer real authority and indicate the editorial territory where the brand already has a presence). Disavowing toxic links is often the first intervention — and produces effects in a few weeks.
Mapping authoritative sources
In every sector, there is a hierarchy of publications that Google and AI systems consider authoritative. National newspapers, industry verticals, thematic portals with real organic traffic, blogs with consolidated Domain Authority. Bliss builds the map of relevant sources for each client — based on the industry, geographic market, and the type of queries where ranking improvement is desired. This map guides all subsequent work.
Editorial strategy for acquisition
The key question is: what can we offer these publications that is genuinely relevant to their readers? Proprietary industry data, original research, expert opinion perspectives, verifiable case studies, authoritative commentary on emerging trends. Bliss builds the editorial plan for link acquisition starting from this question — not from a list of sites to buy space on. The result is content that publications choose to publish because it has autonomous value, generating natural editorial backlinks.
Editor relations and outreach
Authoritative publications don't publish every press release they receive. Building relationships with editors — understanding what they are looking for, pitching at the right time, offering angles their colleagues aren't covering — is the part of link building that cannot be automated. Bliss cultivates these relationships over time: not with mass emails, but with personalized approaches calibrated per publication and per journalist.
Profile monitoring and continuous oversight
A domain's backlink profile evolves continuously: new links acquired, lost links (the linking site changes or closes), new toxic links appearing spontaneously. Bliss monitors the profile on a monthly basis: verification of new referring domains, analysis of anchor text distribution, identification of any new toxic links to disavow, detection of strategic lost links to recover. The profile is presented in a monthly report with variations compared to the previous period and the expected impact on ranking.
Technical SEO and GEO are the same system, optimized on different fronts.
Correct structured data and llms.txt increase quotability in generative AI systems as well as ranking on Google.

Frequently Asked Questions SEO Technique
What is Technical SEO?
Technical SEO is the branch of Search Engine Optimization that deals with a website’s infrastructure-everything that isn’t content or link building, but determines whether Google can properly scan, index, and understand pages. Includes: budget crawl, URL and canonical, Core Web Vitals, structured data, H1 and meta title tags, ALT attributes, backlink profile.
Without a solid technical foundation, content and links do not produce the ranking they deserve. Technical SEO is the foundation upon which any other organic positioning activity is built.
What are the most important SEO techniques on a technical level?
The technical SEO techniques with the greatest impact on ranking are: budget crawl management (prevent Google from wasting resources on non-strategic pages), correct canonicals (prevent the dispersion of authority between duplicate pages), Core Web Vitals (LCP, INP, CLS below Google quality thresholds), schema.org structured data (for rich snippets and AI visibility), H1 normalization and meta titles, image ALT attributes, audit and backlink profile misavow.
The order of priority depends on the specific domain situation – there is no one-size-fits-all checklist.
What is crawl budget and why is it important for SEO?
The crawl budget is the amount of resources Googlebot devotes to crawling a site over a given period. If the site has many low-value pages-parametric URLs, filter variants, duplicate pages-Google scans them instead of strategy pages, which are indexed late or not updated.
Managing the crawl budget through robots.txt, canonical, sitemap, and URL architecture is one of the technical interventions with the greatest impact on ranking, especially for sites with large catalogs or complex legacy architectures.
What are Core Web Vitals and how do they affect positioning?
Core Web Vitals are the three user experience metrics used by Google as a ranking signal: Largest Contentful Paint (LCP – main content loading speed, threshold: <2.5s), Interaction to Next Paint (INP – responsiveness to interactions, threshold: <200ms), and Cumulative Layout Shift (CLS – visual stability, threshold: <0.1).
Pages that exceed these thresholds receive a ranking advantage over pages with equivalent content but worse performance. Bliss optimizes them page by page, starting with strategic URLs for positioning.
What is structured data and how does it improve technical SEO?
Structured data is schema.org markup in JSON-LD format that describes to Google the type of content present on a page: Organization, Service, Product, Article, FAQPage, BreadcrumbList, Event. They enable the activation of rich snippets in SERPs and improve readability by generative AI systems.
A site without structured data is a site that Google and language models read less accurately. The emerging standard llms.txt file adds a layer of direct communication with AI templates about the site’s structure and strategy pages.
How do you conduct a technical SEO audit?
A technical SEO audit maps domain status across six areas: crawling and indexing (robots.txt, sitemap, GSC coverage), URL and canonical structure, Core Web Vitals and performance (PageSpeed, CrUX), structured data, technical on-page optimization (H1, meta, ALT), and backlink profiling.
The output is a list of critical issues sorted by priority and expected impact – not an indistinct list of “to-dos.” Bliss produces the audit before any operational proposal: you can’t build a plan without knowing where to start.
How does ranking change with Google AI Overviews?
Google’s AI Overviews (powered by Gemini) appear above traditional organic results on many informational and transactional queries. A site cited in an AI Overview receives visibility even from low organic locations. Bliss works on organic ranking and quotability in AI Overviews as an integrated system: the semantic structure that improves organic ranking is the same as that that increases the likelihood of being cited in generative responses.
How much does a Google ranking agency cost?
The cost of an agency to rank on Google varies depending on the competitiveness of the industry, the current state of the domain, and the defined objectives. Bliss works with a monthly retainer model that includes initial audit, strategic plan, ongoing execution, and monthly reporting. The cost is defined after a free preliminary assessment of the domain and the competitive territory.
