About SEO Instrumenti

Checks with clearly stated methods and sources

SEO Instrumenti brings together checks for technical SEO, content, domains, performance and security. It was built for the Bulgarian market and is fully available in English.

Submitted data URL, domain or text Only what the check needs

Check Validation and analysis With stated limitations

Result Evidence, explanation, next step With stated sources and method

Each tool states how it turns submitted data into a result.

Desk with printed website wireframes, review notes and a magnifying glass for a manual audit — Before a check is published, its input, result and explanatory content are reviewed as one workflow.

Purpose

Why the platform exists

Our aim is to keep frequently used checks in one place and make their results easy to understand. We distinguish measured data, likely causes and matters that an automated check cannot establish.

Core tools work without registration. An account adds only features with a clear purpose: favourites, history and reports you explicitly save.

Shared technical foundation

Shared engines, purpose-built tools

Related tools reuse the same analysis engines. Validation, network safety and result structure therefore remain consistent.

Page analysis

A controlled HTTP fetch provides the HTML used to inspect metadata, headings, links, images, canonical URLs, robots directives and structured data.

Domain and network

DNS, RDAP, IP and TLS requests share validation and are limited to permitted public addresses.

Text analysis

Word counts, frequency, phrase sequences, readability and text transformations use shared rules and run locally whenever possible.

Operating principles

What every result should make clear

Traceable evidence: each report identifies its data source, method and practical limits.
Bounded network access: unsafe protocols, private addresses, excessive redirects, response sizes and timeouts are blocked.
Minimal retention: submitted data is not stored as a report unless the user explicitly saves it.
Accessible interface: forms, navigation and results support keyboard use, screen readers and small screens.
